ATLAS Measurements of CP-Violation and Rare Decays Processes with Beauty Mesons / Reznicek, Pavel (Charles University (CZ)) /ATLAS Collaboration
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 $B_s$ meson system. This talk will focus on the latest results from the ATLAS collaboration, such as rare processes $B^0_s \to \mu\mu$ and $B^0_d \to \mu\mu$, and CP violation in $B^0_s \to J/\psi\phi$ decays. [...]

Study of $\Xi _{b}^{ - }$ Baryons Reconstruction on CMS Data / Ivanov, K M (Moscow, MIPT)
This paper is dedicated to the experimental study of $\Xi _{b}^{ - }$ baryons reconstruction using the data collected by the CMS experiment at the LHC in 2016–2018 in proton–proton collisions with center-of-mass energy $\sqrt s = 13$ TeV, corresponding to an integrated luminosity of 140 fb$^{–1}$. The obtained signal yield of $\Xi _{b}^{ - } \to J{\text{/}}\psi {{\Xi }^{ - }}$ decay mode is more than 900 events, where $J{\text{/}}\psi \to {{\mu }^{ + }}{{\mu }^{ - }}$,${{\Xi }^{ - }} \to \Lambda {{\pi }^{ - }}$, $\Lambda \to p{{\pi }^{ - }}$.

CP violation in Bs to J/psi phi : update from ATLAS / Simsek, Sinem (Istanbul Bilgi University) /ATLAS Collaboration
In this talk, the measurement of the Bs → J/psi phi decay parameters using 80.5 fb−1 of integrated luminosity collected with the ATLAS detector from 13 TeV proton–proton collisions at the LHC is presented. The measured parameters include the CP-violating phase phi_s, the width difference DeltaGamma_s between the Bs meson mass eigenstates and the average decay width Gamma_s. [...]
