Jet radius dependence of dijet momentum balance and suppression in Pb+Pb collisions at 5.02 TeV with the ATLAS detector
This paper describes a measurement of the jet radius dependence of the dijet momentum balance between leading back-to-back jets in 1.72 $nb^{-1}$ of Pb+Pb collisions collected in 2018 and 255 pb$^{-1}$ of $pp$ collisions collected in 2017 by the ATLAS detector at the LHC. [...]

Simultaneous determination of the CKM angle $\gamma$ and parameters related to mixing and $C\!P$ violation in the charm sector /LHCb Collaboration
A combination of measurements sensitive to the $C\!P$-violation angle $\gamma$ of the Cabibbo-Kobayashi-Maskawa unitarity triangle, to the charm mixing parameters that describe oscillations between $D^0$ and $\bar{D}^0$ mesons, and to the $C\!P$ asymmetries in the $D^0 \!\to K^+ K^-$ and $D^0 \!\to \pi^+ \pi^-$ decays is performed. All relevant beauty and charm results obtained with the data collected with the LHCb detector at CERN's Large Hadron Collider to date are included. [...]

(IISER, Pune) ; Giacalone, Giuliano (CERN ; Heidelberg U.) ; Kirchner, Andreas (Heidelberg U.) ; Ollitrault, Jean-Yves (IPhT, Saclay)
Peculiar phenomena have been observed in analyses of anisotropic flow ($v_n$) fluctuations in ultracentral nucleus-nucleus collisions: The fourth-order cumulant of the elliptic flow ($v_2$) distribution changes sign. [...]
