The soaring demand for intelligent mobile applications calls for deploying powerful deep neural networks (DNNs) on mobile devices. However, the outstanding performance of DNNs notoriously relies on increasingly complex models, which in turn is associated with an increase in computational expense far surpassing mobile devices' capacity. What is worse, app service providers need to collect and utilize a large volume of users' data, which contain sensitive information, to build the sophisticated DNN models. Directly deploying these models on public mobile devices presents prohibitive privacy risk. To benefit from the on-device deep learning without the capacity and privacy concerns, we design a private model compression framework RONA. Following the knowledge distillation paradigm, we jointly use hint learning, distillation learning, and self learning to train a compact and fast neural network. The knowledge distilled from the cumbersome model is adaptively bounded and carefully perturbed to enforce differential privacy. We further propose an elegant query sample selection method to reduce the number of queries and control the privacy loss. A series of empirical evaluations as well as the implementation on an Android mobile device show that RONA can not only compress cumbersome models efficiently but also provide a strong privacy guarantee. For example, on SVHN, when a meaningful (9:83;10-6)-differential privacy is guaranteed, the compact model trained by RONA can obtain 20× compression ratio and 19× speed-up with merely 0.97% accuracy loss.

A search for direct CP violation in the Cabibbo-suppressed decay Ds+ → K−K+K+ and in the doubly Cabibbo-suppressed decay D+ → K−K+K+ is reported. The analysis is performed with data collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 5.6 fb−1. The search is conducted by comparing the D(s)+ and D(s)- Dalitz-plot distributions through a model-independent binned technique, based on fits to the K−K+K+ invariant-mass distributions, with a total of 0.97 (1.27) million Ds+ (D+) signal candidates. The results are given as p-values for the hypothesis of CP conservation and are found to be 13.3% for the Ds+ → K−K+K+ decay and 31.6% for the D+ → K−K+K+ decay. No evidence for CP violation is observed in these decays. © 2023, CC BY.

The measurement of charmonium states produced in proton-neon ( $$p\text {Ne}$$ ) collisions by the LHCb experiment in its fixed-target configuration is presented. The production of $${{J} \hspace{-1.66656pt}/\hspace{-1.111pt}\psi }$$ and $$\psi {(2S)}$$ mesons is studied with a beam of 2.5 $$\mathrm{\,Te\hspace{-1.00006pt}V}$$ protons colliding on gaseous neon targets at rest, corresponding to a nucleon-nucleon centre-of-mass energy $$\sqrt{s_{\scriptscriptstyle \text {NN}}} =68.5\mathrm{\,Ge\hspace{-1.00006pt}V} $$ . The data sample corresponds to an integrated luminosity of $$21.7\pm 1.4 $$ nb $$^{-1}$$ . The $${{J} \hspace{-1.66656pt}/\hspace{-1.111pt}\psi }$$ and $$\psi {(2S)}$$ hadrons are reconstructed in $$\mu ^+$$ $$\mu ^-$$ final states. The $${{J} \hspace{-1.66656pt}/\hspace{-1.111pt}\psi }$$ production cross-section per target nucleon in the centre-of-mass rapidity range $$y^\star \in [-2.29, 0]$$ is found to be $$506 \pm 8 \pm 46 \text { nb/nucleon}$$ . The ratio of $${{J} \hspace{-1.66656pt}/\hspace{-1.111pt}\psi }$$ and $$D^0$$ cross-sections is evaluated to $$(1.06 \pm 0.02 \pm 0.09)\%$$ . The $$\psi {(2S)}$$ to $${{J} \hspace{-1.66656pt}/\hspace{-1.111pt}\psi }$$ relative production rate is found to be $$(1.67 \pm 0.27\pm 0.10)\%$$ in good agreement with other measurements involving beam and target nuclei of similar sizes.

Evidence for the decays B0→ D̅(∗)0 and updated measurements of the branching fractions of the Bs0→ D̅(∗)0 decays

arXiv

引用

arXiv 2023年

Evidence for the decays B0→ D̅0 and B0→ D̅∗0 is reported with a significance of 3.6 σ and 4.3 σ, respectively. The analysis employs pp collision data at centreof-mass energies √s = 7, 8 and 13 TeV collected by the LHCb detector and corresponding to an integrated luminosity of 9 fb−1. The branching fractions are measured to be B(B0→ D̅0) = (7.7 ± 2.1 ± 0.7 ± 0.7) × 10−7, B(B0→ D̅∗0) = (2.2 ± 0.5 ± 0.2 ± 0.2) × 10−6. In these results, the first uncertainty is statistical, the second systematic, and the third is related to the branching fraction of the B0→ D̅0K+K−decay, used for normalisation. By combining the branching fractions of the decays B0→ D̅(∗)0 and B0→ D̅(∗)0ω, the ω- mixing angle δ is constrained to be tan2δ = (3.6 ± 0.7 ± 0.4) × 10−3, where the first uncertainty is statistical and the second systematic. An updated measurement of the branching fractions of the Bs0→ D̅(∗)0 decays, which can be used to determine the CKM angle γ, leads to B(Bs0→ D̅0) = (2.30 ± 0.10 ± 0.11 ± 0.20) × 10−5, B(Bs0→ D̅∗0) = (3.17 ± 0.16 ± 0.17 ± 0.27) × 10−5 © 2023, CC BY.

A search is presented for high-mass exclusive diphoton production via photon-photon fusion in proton-proton collisions at s=13 TeV in events where both protons survive the interaction. The analysis utilizes data corresponding to an integrated luminosity of 103 fb−1 collected in 2016–2018 with the central CMS detector and the CMS and TOTEM precision proton spectrometer (PPS). Events that have two photons with high transverse momenta (pTγ>100 GeV), back-to-back in azimuth, and with a large diphoton invariant mass (mγγ>350 GeV) are selected. To remove the dominant inclusive diphoton backgrounds, the kinematic properties of the protons detected in PPS are required to match those of the central diphoton system. Only events having opposite-side forward protons detected with a fractional momentum loss between 0.035 and 0.15 (0.18) for the detectors on the negative (positive) side of CMS are considered. One exclusive diphoton candidate is observed for an expected background of 1.1 events. Limits at 95% confidence level are derived for the four-photon anomalous coupling parameters |ζ1|<0.073 TeV−4 and |ζ2|<0.15 TeV−4, using an effective field theory. Additionally, upper limits are placed on the production of axionlike particles with coupling strength to photons f−1 that varies from 0.03 TeV−1 to 1 TeV−1 over the mass range from 500 to 2000 GeV.

This paper presents an energy resolution study of the JUNO experiment, incorporating the latest knowledge acquired during the detector construction phase. The determination of neutrino mass ordering in JUNO requires an exceptional energy resolution better than 3% at 1 MeV. To achieve this ambitious goal, significant efforts have been undertaken in the design and production of the key components of the JUNO detector. Various factors affecting the detection of inverse beta decay signals have an impact on the energy resolution, extending beyond the statistical fluctuations of the detected number of photons, such as the properties of the liquid scintillator, performance of photomultiplier tubes, and the energy reconstruction algorithm. To account for these effects, a full JUNO simulation and reconstruction approach is employed. This enables the modeling of all relevant effects and the evaluation of associated inputs to accurately estimate the energy resolution. The results of study reveal an energy resolution of 2.95% at 1 MeV. Furthermore, this study assesses the contribution of major effects to the overall energy resolution budget. This analysis serves as a reference for interpreting future measurements of energy resolution during JUNO data collection. Moreover, it provides a guideline for comprehending the energy resolution characteristics of liquid scintillator-based detectors. © 2024, CC BY.

The central exclusive production of charged-hadron pairs in pp collisions at a center-of-mass energy of 13 TeV is examined, based on data collected in a special high-β* run of the LHC. The nonresonant continuum processes are studied with the invariant mass of the centrally produced two-pion system in the resonance-free region, mπ+π−<0.7 or mπ+π−>1.8 GeV. Differential cross sections as functions of the azimuthal angle between the surviving protons, squared exchanged four-momenta, and mπ+π− are measured in a wide region of scattered proton transverse momenta, between 0.2 and 0.8 GeV, and for pion rapidities |y|<2. A rich structure of interactions related to double-pomeron exchange is observed. A parabolic minimum in the distribution of the two-proton azimuthal angle is observed for the first time. It can be interpreted as an effect of additional pomeron exchanges between the protons from the interference between the bare and the rescattered amplitudes. After model tuning, various physical quantities are determined that are related to the pomeron cross section, proton-pomeron and meson-pomeron form factors, pomeron trajectory and intercept, and coefficients of diffractive eigenstates of the proton.
