The first m.asurem.nts of elliptic flow of (Equation presented) using m.ltiparticle cum.lants in Pb-Pb collisions at √sNN = 5.02 TeV are presented. Results obtained with two- (v2m.) and four-particle cum.lants (v2m.) are shown as a function of transverse m.m.ntum. pT, for various collision centrality intervals. Com.ining the data for both v2m. and v2m. also allows us to report the first m.asurem.nts of the m.an elliptic flow, elliptic flow fluctuations, and relative elliptic flow fluctuations for various hadron species. These observables probe the event-by-event eccentricity fluctuations in the initial state and the contributions from.the dynam.c evolution of the expanding quark-gluon plasm.. The characteristic features observed in previous pT-differential anisotropic flow m.asurem.nts for identified hadrons with two-particle correlations, nam.ly the m.ss ordering at low pT and the approxim.te scaling with the num.er of constituent quarks at interm.diate pT, are sim.larly present in the four-particle correlations and the com.inations of v2m. and v2m.. In addition, a particle species dependence of flow fluctuations is observed that could indicate a significant contribution from.final state hadronic interactions. The com.arison between experim.ntal m.asurem.nts and CoLBT m.del calculations, which com.ine the various physics processes of hydrodynam.cs, quark coalescence, and jet fragm.ntation, illustrates their im.ortance over a wide pT range. © 2022, CC BY.

We present JWST NIRCam.im.ging targeting 13 z∼3 infrared-lum.nous (LIR ∼ 5×1012L) galaxies from.the ALESS survey with uniquely deep, high-resolution (0.08′′–0.16′′) ALm. 870µm.im.ging. The 2.0-4.4µm.(observed fram.) NIRCam.im.ging reveals the rest-fram. near-infrared stellar em.ssion in these subm.llim.ter-selected galaxies (Sm.s) at the sam. (sub-)kpc resolution as the 870µm.dust continuum. The newly revealed stellar m.rphologies show striking sim.larities with the dust continuum.m.rphologies at 870µm. with the centers and position angles agreeing for m.st sources, clearly illustrating that the spatial offsets reported previously between the 870µm.and HST m.rphologies were due to strong differential dust obscuration. The F444W sizes are 78±21% larger than those m.asured at 870µm. in contrast to recent results from.hydrodynam.cal sim.lations that predict larger 870µm.sizes. We report evidence for significant dust obscuration in F444W for the highest-redshift sources, em.hasizing the im.ortance of longer-wavelength m.RI im.ging. The m.jority of the sources show evidence that they are undergoing m.rgers/interactions, including tidal tails/plum.s—som. of which are also detected at 870µm. We find a clear correlation between NIRCam.colors and 870µm.surface brightness on ∼1 kpc scales, indicating that the galaxies are prim.rily red due to dust—not stellar age—and we show that the dust structure on ∼kpc-scales is broadly sim.lar to that in nearby galaxies. Finally, we find no strong stellar bars in the rest-fram. near-infrared, suggesting the extended bar-like features seen at 870µm.are highly obscured and/or gas-dom.nated structures that are likely early precursors to significant bulge growth. © 2024, CC BY.

Hadronic resonances are used to probe the hadron gas produced in the late stage of heavy-ion collisions since they decay on the sam. tim.scale, of the order of 1 to 10 fm.c, as the decoupling tim. of the system. In the hadron gas, (pseudo)elastic scatterings am.ng the products of resonances that decayed before the kinetic freeze-out and regeneration processes counteract each other, the net effect depending on the resonance lifetim., the duration of the hadronic phase, and the hadronic cross sections at play. In this context, the Σ(1385)± particle is of particular interest as m.dels predict that regeneration dom.nates over rescattering despite its relatively short lifetim. of about 5.5 fm.c. The first m.asurem.nt of the Σ(1385)± resonance production at m.drapidity in Pb-Pb collisions at √sNN = 5.02 TeV with the ALICE detector is presented in this Letter. The resonances are reconstructed via their hadronic decay channel, Λπ, as a function of the transverse m.m.ntum.(pT) and the collision centrality. The results are discussed in com.arison with the m.asured yield of pions and with expectations from.the statistical hadronization m.del as well as com.only em.loyed event generators, including PYTHIA8/Angantyr and EPOS3 coupled to the UrQm. hadronic cascade afterburner. None of the m.dels can describe the data. For Σ(1385)±, a sim.lar behaviour as K∗(892)0 is observed in data unlike the predictions of EPOS3 with afterburner. © 2022, CC BY.

Two-particle correlations with K0S, Λ/(eq), and charged hadrons as trigger particles in the transverse m.m.ntum.range 8 T,trig T,assoc NN = 5.02 TeV with the ALICE detector at the LHC. After subtracting the contributions of the flow background, the per-trigger yields are extracted on both the near and away sides, and the ratio in Pb-Pb collisions with respect to pp collisions (IAA) is com.uted. The per-trigger yield in Pb-Pb collisions on the away side is strongly suppressed to the level of IAA ≈ 0.6 for pT,assoc > 3 GeV/c as expected from.strong in-m.dium.energy loss, while an enhancem.nt develops at low pT,assoc on both the near and away sides, reaching IAA ≈ 1.8 and 2.7 respectively. These findings are in good agreem.nt with previous ALICE m.asurem.nts from.two-particle correlations triggered by neutral pions (π0-h) and charged hadrons (h-h) in Pb-Pb collisions at √sNN = 2.76 TeV. m.reover, the correlations with K0S m.sons and Λ/Λ baryons as trigger particles are com.ared to those of inclusive charged hadrons.

The correlations between event-by-event fluctuations of sym.etry planes are m.asured in Pb–Pb collisions at a centre-of-m.ss energy per nucleon pair √sNN = 5.02 TeV recorded by the ALICE detector at the Large Hadron Collider. This analysis is conducted using the Gaussian Estim.tor technique, which is insensitive to biases from.correlations between different flow am.litudes. The study presents, for the first tim., the centrality dependence of correlations involving up to five different sym.etry planes. The correlation strength varies depending on the harm.nic order of the sym.etry plane and the collision centrality. Com.arisons with m.asurem.nts from.lower energies indicate no significant differences within uncertainties. Additionally, the results are com.ared with hydrodynam.c m.del calculations. Although the m.del predictions provide a qualitative explanation of the experim.ntal results, they overestim.te the data for som. observables. This is particularly true for correlators that are sensitive to the non-linear response of the m.dium.to initial-state anisotropies in the collision system. As these new correlators provide unique inform.tion — independent of flow am.litudes — their usage in future m.del developm.nts can further constrain the properties of the strongly-interacting m.tter created in ultrarelativistic heavy-ion collisions. © 2024, CC BY.

This paper presents a fully-corrected m.asurem.nt of the energy-energy correlator (EEC) within jets in pp collisions. The EEC traces the energy flow as a highly energetic parton undergoes a QCD shower followed by the confinem.nt of partons into hadrons, probing the correlation function of the energy flow inside jets. The EEC observable is m.asured as a function of the charged particle pair angular distance, RL, for 20 chTjet L), a good agreem.nt between the data and a next-to-leading-log perturbative QCD calculation is observed. In the non-perturbative region (sm.ll RL), the data exhibits a linear RL dependence. There is a transition region in between, characterized by a turnover in the EEC distribution, corresponding to the confinem.nt process. The peak of this transition region is located at 2.39±0.17 GeV/c/〈pchTjet〉 for jets of various energies, indicating a com.on energy scale for the hadronization process. State-of-the-art m.nte Carlo event generators are com.ared with the m.asurem.nts, and can be used to constrain the parton shower and hadronization m.chanism.. © 2024, CC BY.

Observation of flow angle and flow m.gnitude fluctuations in Pb-Pb collisions at √sNN = 5.02 TeV at the CERN Large Hadron Collider

arXiv

引用

arXiv 2022年

This Letter reports on the first m.asurem.nts of transverse m.m.ntum.dependent flow angle Ψn and flow m.gnitude vn fluctuations, determ.ned using new four-particle correlators. The m.asurem.nts are perform.d for various centralities in Pb-Pb collisions at a centre-of-m.ss energy per nucleon pair of √sNN = 5.02 TeV with ALICE at the CERN Large Hadron Collider. Both flow angle and flow m.gnitude fluctuations are observed in the presented centrality ranges and are strongest in the m.st central collisions and for a transverse m.m.ntum.pT > 2 GeV/c. Com.arison with theoretical m.dels, including iEBE-VISHNU, m.SIC, and Am.T, show that the m.asurem.nts exhibit unique sensitivities to the initial state of heavy-ion collisions. © 2022, CC BY.

The papers in this special section address distributed signal processing applications that support security and privacy in networked cyber-physical system.. Networked cyber-physical system. (CPSs) are engineering system. with integrated com.utational and com.unication capabilities that interact with hum.ns through cyber space. The CPSs have recently em.rged in several practical applications of significant engineering im.ortance including aerospace, industrial/m.nufacturing process control, m.ltim.dia networks, transportation system., power grids, and m.dical system.. The CPSs typically consist of both wireless and wired sensor/agent networks with different capacity/reliability levels where the em.hasis is on real-tim. operations, and perform.ng distributed, secure, and optim.l sensing/processing is the key concern. To satisfy these requirem.nts of the CPSs, it is of param.unt im.ortance to design innovative Signal Processing tools to provide unprecedented perform.nce and resource utilization efficiency. © 2015 IEEE.

The purpose of this panel is to discuss the state of the art in digital twin for m.nufacturing research and practice from.the perspective of the sim.lation com.unity. The panelists com. from.the US, Europe, and Asia representing academ.a, industry, and governm.nt. This paper begins with a short introduction to digital twins and then each panelist provides prelim.nary thoughts on concept, definitions, challenges, im.lem.ntations, relevant standard activities, and future directions. Two panelists also report their digital twin projects and lessons learned. The panelists m.y have different viewpoints and m.y not totally agree with each other on som. of the argum.nts, but the intention of the panel is not to unify researchers' thinking, but to list the research questions, initiate a deeper discussion, and try to help researchers in the sim.lation com.unity with their future study topics on digital twins for m.nufacturing.
