43. High Precision Muon Reconstruction Performance with ATLAS at LHC

Siyuan Yan

9/7/22, 4:00 PM

Muon reconstruction performance plays a crucial role in the precision and sensitivity of the Large Hadron Collider (LHC) data analysis of the ATLAS experiment. The 139 fb-1 of proton-proton collision data collected during the LHC Run-2 poses both a challenge and opportunity for the detector performance. Using di-muon resonances we are able to calibrate to sub per-mil accuracy the detector...

44. Tests of Standard Model with beauty meson rare decay processes and CP-violation measurements at ATLAS

Lukas Novotny

9/7/22, 4:05 PM

The ATLAS experiment has performed measurements of B-meson rare decays proceeding via suppressed electroweak flavour changing neutral currents, and of mixing and CP violation in the neutral B0s meson system. This poster will focus on the latest results from the ATLAS collaboration, such as rare processes B0s→μμ and B0d→μμ, and CP violation in B0s→J/ψ ϕ decays, where the CP-violation phase ϕs...

46. Response of the ATLAS Tile Calorimeter at Test Beams using Phase II upgrade readout

Tamar Zakareishvili (Ivane Javakhishvili Tbilisi State University (GE))

9/7/22, 4:10 PM

The Large Hadron Collider (LHC) Phase II upgrade aims to increase the accelerator luminosity by a factor of 5-10. Due to the expected higher radiation levels and the aging of the current electronics, a new readout system of the ATLAS experiment hadronic calorimeter (TileCal) is needed. A prototype of the upgrade TileCal electronics has been tested using the beam from the Super Proton...

47. Response of the ATLAS Tile Calorimeter to single isolated charged hadrons

Archil Durglishvili (Ivane Javakhishvili Tbilisi State University (GE))

9/7/22, 4:15 PM

The response of the ATLAS hadronic Tile Calorimeter to single isolated
charged hadrons is probed analysing of LHC proton-proton collisions data
at √s = 13 TeV collected in 2017 and corresponding to an integrated
luminosity of 144.9 pb-1. The calorimeter response is determined as the
ratio of the energy deposited in the calorimeter (E) divided by the
momentum measured in the ATLAS Inner...

48. Physics Prospects of the JUNO Experiment

Mariam Rifai

9/7/22, 4:20 PM

The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator detector with the main goal to determine the neutrino mass ordering (NMO). JUNO construction in southern China,in an underground laboratory with 650 m rock overburden, is expected to be completed by the end of 2023.
Thanks to high scintillation light yield, high transparency, 78% optical coverage and large...

49. Ultrahigh Vacuum Developments for the Einstein Telescope

Prof. Achim Stahl (Rheinisch Westfaelische Tech. Hoch. (DE))

9/7/22, 4:25 PM

The Einstein Telescope, the European Gravitational Detector of the next generation, will need the largest ultrahigh vacuum system ever build. I will present some of the development towards this system.

50. Broad Band Waveguide to Coaxial Transition for HOM Suppression in RF Cavities for Future Synchrotron Light Sources

SHALVA BILANISHVILI

9/7/22, 4:30 PM

In the modern storage ring light sources, exploiting multi-bunch beams, the longitudinal and transverse coupled bunch instabilities are predominantly driven by higher order modes (HOM) of the accelerator RF cavities. In order to suppress the HOM to a harmless level, we propose using a modified broadband waveguide to coaxial line transitions placed on the cavity body, similar to those used for...

51. Extraction of the reactor neutrino spectral distortion in the Double Chooz experiment

Philipp Soldin Not Supplied

9/7/22, 4:35 PM

Double Chooz was a reactor neutrino disappearance experiment operating between 2011 and 2018. Its primary purpose was precisely measuring the neutrino mixing angle $\theta_{13}$. The experimental setup consisted of two identical liquid scintillator detectors at average baselines of about 400 m and 1 km to two nuclear reactor cores in Chooz, France. The neutrinos were detected by measuring the...

54. Partition Pooling for Convolutional Graph Network Applications in Particle Physics

Markus Bachlechner

9/7/22, 4:45 PM

Convolutional Graph Networks (CGN) can be used for effective parameter estimations and event classification based on sensor-level data. However, if applied to the static sensor arrangement of modern particle detectors, the CGN performance can be limited by the considerable number of sensors. A scheme analogous to conventional pooling on images that uses graph partitioning to create pooling...

56. The KM3NeT Project

Giorgi Kistauri (Tbilisi State University)

9/7/22, 4:50 PM

Abstract. KM3NeT is a research infrastructure housing the next generation of Cherenkov neutrino telescopes. It consists of two detectors with similar technology currently under construction in the Mediterranean Sea: ARCA (off-shore Sicily, Italy) and ORCA (off-shore Toulon, France) dedicated to Astroparticle and Oscillation Research with Cosmics in the Abyss, respectively. ARCA will...

57. Recent results from the KM3NeT Experiment

Gogita Papalashvili (HEPI, TSU)

9/7/22, 4:55 PM

KM3NeT is a European research infrastructure project currently under construction
at two locations in the Mediterranean Sea. The project aims to detect the neutrinos in the
energy range from a few GeV up to a few PeV with two detectors: ORCA (Oscillation
Research with Cosmics in the Abyss) for low energy neutrinos and ARCA (Astroparti-
cle Research with Cosmics in the Abyss) for high...

52. Current status and prospects in the field of solar neutrinos

Luca Pelicci (Forschungszentrum Jülich and Aachen University)

Energy production in our Sun, carried out through the fusion of hydrogen to helium, is accounted for by two distinct processes: the proton-proton (pp) chain and the carbon- nitrogen-oxygen (CNO) cycle. Both sequences of reactions involve the production of several electron flavor neutrinos, the so-called solar neutrinos. Over the last decades, their detection has brought to light a useful...

45. Measurement of electroweak Z(nunu)y production and limits on anomalous quartic gauge couplings in pp collisions at sqrt(s)=13 TeV with the ATLAS detector

Anastasia Kurova

The electroweak production of Z(nunu)y in association with two jets is studied in a regime with a photon of high transverse momentum above 150 GeV using proton-proton collisions at centre-of-mass energy of 13 TeV at the Large Hadron Collider. The analysis uses a data sample with an integrated luminosity of 139 fb-1 collected by the ATLAS detector during the 2015-2018 LHC data taking period....
