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- A nd 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.

РНЕМТ AlxGa1-xAs/InyGa1-yAs гетероструктуры являются одним из самых широко используемых базовых материалов в СВЧ электронике для создания транзисторов и монолитных интегральных схем (МИС). Данные структуры содержат большое число слоев, как основных, так и вспомогательных, из твердых растворов AlxGa1-xAs и InyGa1-yAs. Для получения требуемой зонной структуры и характеристик образцов необходимо жестко контролировать состав и толщину данных слоев. Цель работы состояла в реализации технологии РНЕМТ гетероструктур с использованием методов нанометрологии, обеспечивающими точность и воспроизводимость технологических параметров не хуже 95%. Для роста на установке МЛЭ Riber Compact 21T использовались импортные ОСЧ металлы производства Azelis Electronics. Предельный вакуум в камере роста при замороженных криопанелях и с перекрытым потоком As4 составлял до 1-2х10-11 Торр. Одним из важных факторов получения стабильной и воспроизводимой скорости роста, состава и толщины слоев РНЕМТ гетероструктур являлось получение долговременной стабильности потоков и учет быстрых переходных процессов при открытии заслонок.

Two-particle correlations in azimuthal angle and pseudorapidity in central 7Be + 9Be collisions at the CERN Super Proton Synchrotron
(2020) Aduszkiewicz, A.; Andronov, E. V.; Anticic, T.; Babkin, V.; Brandin, A.; Golosov, O.; Kargin, N.; Kashirin, E.; Morozov, S.; Selyuzhenkov, I.; Strikhanov, M.; Taranenko, A.; Брандин, Андрей Владимирович; Голосов, Олег Владимирович; Каргин, Николай Иванович; Стриханов, Михаил Николаевич; Тараненко, Аркадий Владимирович
© 2020, The Author(s).A measurement of charged hadron pair correlations in two-dimensional Δ ηΔ ϕ space is presented. The analysis is based on total 30 million central Be + Be collisions observed in the NA61/SHINE detector at the CERN SPS for incident beam momenta of 19A, 30A, 40A, 75A, and 150A Ge/c. Measurements were carried out for unlike-sign and like-sign charge hadron pairs independently. The C(Δ η, Δ ϕ) correlation functions were compared with results from a similar analysis on p + p interactions at similar beam momenta per nucleon. General trends of the back-to-back correlations are similar in central Be + Be collisions and p + p interactions, but are suppressed in magnitude due to the increased combinatorial background. Predictions from the Epos and UrQMD models are compared to the measurements. Evolution of an enhancement around (Δ η, Δ ϕ) = (0 , 0) with incident energy is observed in central Be + Be collisions. It is not predicted by both models and almost non-existing in proton–proton collisions at the same momentum per nucleon.

Open charm measurements in NA61/SHINE at CERN SPS
(2019) Staszel, P.; Aduszkiewicz, A.; Andronov, E. V.; Anticic, T.; Brandin, A. V.; Golosov, O.; Kargin, N.; Kashirin, E.; Morozov, S.; Strikhanov, M.; Taranenko, A.; Брандин, Андрей Владимирович; Голосов, Олег Владимирович; Каргин, Николай Иванович; Стриханов, Михаил Николаевич; Тараненко, Аркадий Владимирович
The measurements of open charm production was proposed as an important tool to investigate the properties of the hot and dense matter formed in nucleus-nucleus collisions as well as to provide the means for model independent interpretation of the existing data on J/Psi suppression. Recently, the experimental setup of the NA61/SHINE experiment was supplemented with a Vertex Detector which was motivated by the importance and the possibility of the first direct measurements of open charm meson production in heavy ion collisions at SPS energies. First test data taken in December 2016 on Pb+Pb collisions at 150A GeV/c allowed to validate the general concept of D-0 meson detection via its D-0 -> pi(+) + K- decay channel and delivered a first indication of open charm production. The physics motivation of open charm measurements at SPS energies, pilot results on open charm production, and finally, the future plans of open charm measurements in the NA61/SHINE experiment after LS2 are presented.

Measurements of production and inelastic cross sections for p plus C, p plus Be, and p + Al at 60 GeV/c and p plus C and p + Be at 120 GeV/c
(2019) Aduszkiewicz, A.; Andronov, E. V.; Anticic, T.; Babkin, V.; Brandin, A. V.; Golosov, O.; Kargin, N.; Kashirin, E.; Morozov, S.; Selyuzhenkov, I.; Strikhanov, M.; Taranenko, A.; Брандин, Андрей Владимирович; Голосов, Олег Владимирович; Каргин, Николай Иванович; Стриханов, Михаил Николаевич; Тараненко, Аркадий Владимирович
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 is performed using the NA61/SHINE spectrometer at the CERN Super Proton Synchrotron. First measurements are obtained using protons at 120 GeV/c, while the results for protons at 60 GeV/c are 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.

Search for the critical point by the NA61/SHINE experiment
(2019) Andronov, E.; Aduszkiewicz, A.; Andronov, E. V.; Anticic, T.; Brandin, A.; Golosov, O.; Kargin, N.; Kashirin, E.; Morozov, S.; Strikhanov, M.; Taranenko, A.; Брандин, Андрей Владимирович; Голосов, Олег Владимирович; Каргин, Николай Иванович; Стриханов, Михаил Николаевич; Тараненко, Аркадий Владимирович
NA61/SHINE is a fixed target experiment operating at CERN SPS. Its main goals are to search for the critical point of strongly interacting matter and to study the onset of deconfinement. For these goals a scan of the two dimensional phase diagram (T-mu(B)) is being performed at the SPS by measurements of hadron production in proton-proton, proton-nucleus and nucleus-nucleus interactions as a function of collision energy. In this paper the status of the search for the critical point of strongly interacting matter by the NA61/SHINE Collaboration is presented including recent results on proton intermittency, strongly intensive fluctuation observables of multiplicity and transverse momentum fluctuations. These measurements are expected to be sensitive to the correlation length and, therefore, have the ability to reveal the existence of the critical point via possible non-monotonic behavior. The new NA61/SHINE results are compared to the model predictions.

Preliminary results on the phi (1020) meson production in inelastic proton-proton collisions measured by the NA61/SHINE experiment at the CERN SPS are presented in these proceedings. The results include the first ever differential P-T and y measurements at beam momenta of 40 and 80 GeV and the most ever detailed experimental data at 158 GeV. The comparison of p + p to Pb + Pb results shows a non-trivial system size dependence of the widths of the rapidity distributions for phi mesons, contrasting with that of other hadrons. The results are furthermore compared to the world data on phi meson production, demonstrating the better accuracy achieved by the NA61/SHINE experiment, and to several models. None of the models is found to be able to describe simultaneously the shape of transverse momentum spectra, the shape of rapidity distribution and the total yield.

Measurement of the production cross section of 31 GeV/c protons on carbon via beam attenuation in a 90-cm-long target
(2021) Acharya, A.; Adhikary, H.; Aduszkiewicz, A.; Allison, K. K.; Brandin, A.; Golosov, O.; Kargin, N.; Kashirin, E.; Morozov, S.; Selyuzhenkov, I.; Strikhanov, M.; Taranenko, A.; Брандин, Андрей Владимирович; Голосов, Олег Владимирович; Каргин, Николай Иванович; Стриханов, Михаил Николаевич; Тараненко, Аркадий Владимирович
© 2021 authors.The production cross section of 30.92 GeV/c protons on carbon is measured by the NA61/SHINE spectrometer at the CERN Super Proton Synchrotron by means of beam attenuation in a copy (replica) of the 90-cm-long target of the T2K neutrino oscillation experiment. The employed method for direct production cross-section estimation minimizes model corrections for elastic and quasielastic interactions. The obtained production cross section is σprod=227.6±0.8(stat)-3.2+1.9(sys)-0.8(mod) mb. It is in agreement with previous NA61/SHINE results obtained with a thin carbon target, while providing improved precision with a total fractional uncertainty of less than 2%. This direct measurement will reduce the uncertainty of the T2K neutrino flux prediction.

© 2021, The Author(s).The NA61/SHINE experiment at the CERN Super Proton Synchrotron (SPS) studies the onset of deconfinement in hadron matter by a scan of particle production in collisions of nuclei with various sizes at a set of energies covering the SPS energy range. This paper presents results on inclusive double-differential spectra, transverse momentum and rapidity distributions and mean multiplicities of π±, K±, p and p¯ produced in the 20% most central7Be+9Be collisions at beam momenta of 19A, 30A, 40A, 75A and 150A GeV/c. The energy dependence of the K±/π± ratios as well as of inverse slope parameters of the K± transverse mass distributions are close to those found in inelastic p+p reactions. The new results are compared to the world data on p+p and Pb+Pb collisions as well as to predictions of the Epos, Urqmd, Ampt, Phsd and Smash models.
