Recent results on exclusive production at HERA

38th International Conference on High Energy physics, ICHEP 2016

作者： Przybycien, Mariusz AGH University of Science and Technology Faculty of Physics and Applied Computer Science Al. Mickiewicza 30 Cracow30-059 Poland

Exclusive processes at HERA can lead to a deeper insight into production mechanisms in QCD. A series of processes is presented here. A first measurement is presented of exclusive photoproduction of ρ0 mesons associated with leading neutrons at HERA. The H1 data are interpreted in terms of a double peripheral process, involving pion exchange at the proton vertex followed by elastic photoproduction of a ρ0 meson on the virtual pion. The value of the elastic cross section indicates significant absorptive corrections for the exclusive reaction. Production of exclusive dijets in diffractive deep inelastic e±p scattering has been measured by ZEUS. The results are compared to predictions from models based on different assumptions about the nature of the diffractive exchange. The exclusive deep inelastic electroproduction and photoproduction of Φ(2S) and J/Φ(lS) has been studied by ZEUS. The cross-section ratio σ(Φ(2S))/σ(J/Φ(lS)) has been measured as a function of Q2, W and t. The results are compared to many predictions of QCD-inspired models of exclusive vector-meson production. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).

Artificial molecular states of double quantum dots defined in bilayer graphene are studied with the atomistic tight-binding and its low-energy continuum approximation. We indicate that the extended electron wave functions have opposite parities on sublattices of the layers and that the ground-state wave function components change from bonding to antibonding with the interdot distance. In the weak coupling limit { the most relevant for the quantum dots defined electrostatically { the signatures of the interdot coupling include { for the two-electron ground state formation of states with symmetric or antisymmetric spatial wave functions split by the exchange energy. In the high energy part of the spectrum the states with both electrons in the same dot are found with the splitting of energy levels corresponding to simultaneous tunneling of the electron pair from one dot to the other.

Hardness of Permutation Pattern Matching

Annual ACM-Society for Industrial and applied Mathmatics Symposium on Discrete Algorithms

Permutation Pattern Matching (or PPM) is a decision problem whose input is a pair of permutations π and τ, represented as sequences of integers, and the task is to determine whether τ contains a subsequence order-isomorphic to π. Bose, Buss and Lubiw proved that PPM is NP-complete on general inputs. We show that PPM is NP-complete even when π has no decreasing subsequence of length 3 and τ has no decreasing subsequence of length 4. This provides the first known example of PPM being hard when one or both of π and σ are restricted to a proper hereditary class of permutations. This hardness result is tight in the sense that PPM is known to be polynomial when both π and τ avoid a decreasing subsequence of length 3, as well as when π avoids a decreasing subsequence of length 2. The result is also tight in another sense: we will show that for any hereditary proper subclass C of the class of permutations avoiding a decreasing sequence of length 3, there is a polynomial algorithm solving PPM instances where π is from C and τ is arbitrary. We also obtain analogous hardness and tractability results for the class of so-called skew-merged patterns. From these results, we deduce a complexity dichotomy for the PPM problem restricted to π belonging to Av(α), where Av(α) denotes the class of permutations avoiding a permutation α. Specifically, we show that the problem is polynomial when α is in the set {1, 12, 21,132, 213, 231, 312}, and it is NP-complete for any other α.

This paper presents a microwave gas sensor based on interdigital resonator structure coating with gas sensing material of poly (styrene-co-maleic acid) partial isobutyl/methyl mixed ester (PSE). This sensor was designed on the center of coplanar waveguide (CPW) to operate at 4 GHz with rejection characteristic. The measured results for five samples of ammonia hydroxide concentration (50, 200, 500, 1000, and 2000 ppm) under a static system in the closed chamber at room temperature were obtained. The levels of gas concentration can be impressively detected by measuring the transmission coefficient changes. The proposed sensor can be employed for several applications such as sensing the gas generating from agricultural products.

This paper presents measurements of production cross sections and inelastic cross sections for the following reactions: 60 GeV/c protons with C, Be, Al targets and 120 GeV/c protons with C and Be targets. The analysis was performed using the NA61/SHINE spectrometer at the CERN SPS. First measurements were obtained using protons at 120 GeV/c, while the results for protons at 60 GeV/c were compared with previously published measurements. These interaction cross section measurements are critical inputs for neutrino flux prediction in current and future accelerator-based long-baseline neutrino experiments.

The long-term dependence of Bitcoin (BTC), manifesting itself through a Hurst exponent H > 0.5, is exploited in order to predict future BTC/USD price. A Monte Carlo simulation with 104 geometric fractional Brownian motion realisations is performed as extensions of historical data. The accuracy of statistical inferences is 10%. The most probable Bitcoin price at the beginning of 2018 is 6358 USD. Copyright © 2017, The Authors. All rights reserved.

Precise knowledge of hadron production rates in the generation of neutrino beams is necessary for accelerator-based neutrino experiments to achieve their physics goals. NA61/SHINE, a large-acceptance hadron spectrometer, has recorded hadron+nucleus interactions relevant to ongoing and future long-baseline neutrino experiments at Fermi National Accelerator Laboratory. This paper presents three analyses of interactions of 60 GeV/c π+ with thin, fixed carbon and beryllium targets. Integrated production and inelastic cross sections were measured for both of these reactions. In an analysis of strange, neutral hadron production, differential production multiplicities of KS0, Λ and Λ were measured. Lastly, in an analysis of charged hadron production, differential production multiplicities of π+, π−, K+, K− and protons were measured. These measurements will enable long-baseline neutrino experiments to better constrain predictions of their neutrino flux in order to achieve better precision on their neutrino cross section and oscillation measurements.
