Model-independent measurement of charm mixing parameters in $\bar{B} \rightarrow D^0 ( \rightarrow K_S^0 \pi^+ \pi^-) \mu^- \bar{\nu}_\mu X$
A measurement of charm mixing and $CP$-violating parameters is reported, using $\bar{B} \rightarrow D^0 ( \rightarrow K_S^0 \pi^+ \pi^-) \mu^-\bar{\nu}_\mu X$ decays reconstructed in proton-proton collisions collected by the LHCb experiment during the years 2016 to 2018, corresponding to an integrated luminosity of 5.4 fb$^{-1}$.

Top quark mass and properties in ATLAS and CMS / Wuchterl, Sebastian (DESY)
For standard model (SM) processes involving top quarks, such as top quark-antiquark pair production or single top quark production, the theoretical predictions depend on fundamental parameters of the SM like the top quark mass. [...]

Field-dependent surface resistance for superconducting niobium accelerating cavities-condensed overview / Weingarten, Wolfgang (CERN)
Small (compared to coherence length) weak superconducting defects when located at the surface, combined with the proximity and percolation effects, are claimed responsible for various observations with superconducting rf accelerating cavities with non-constant Q-value..

Measurements of charge-dependent correlations with CMS / Behera, Subash Chandra (Indian Inst. Tech., Madras) /CMS Collaboration
Charge-dependent azimuthal anisotropy Fourier coefficients are measured with two- and three-particle correlations in pPb and PbPb collisions. The difference between positively and negatively charged particles for the second-order two-particle $(v_2\{2\})$ and three-particle $(v_2\{3\})$ coefficients for both pPb and PbPb, and third order two-particle coefficient $(v_3\{2\})$ for PbPb, are presented.

The DAQ and clock distribution system of CMS MIP Timing Detector / Simkina, Polina (IRFU, Saclay) /CMS Collaboration
The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase-II upgrade program to cope with the challenging conditions of the High-Luminosity LHC (HL-LHC). A new timing detector is designed to measure minimum ionizing particles (MIPs) with a time resolution of 30-60 ps during the entire HL-LHC phase. [...]
