Observation of violation in decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1172

The LHCb collaboration measures the time‑dependent CP asymmetry in B⁰ → J/ψ ρ⁰ decays, reporting the first observation of CP violation in this channel and determining the effective…

Measurement of the branching fraction of the decay and isospin asymmetry of decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1193

This paper describes a measurement of the branching fraction using data collected with the LHCb experiment in proton-proton collisions from 2016 to 2018. The dat…

Polarization measurement of and baryons in Ne collisions at GeV

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1174

The first measurement of the polarization of charm baryons by the LHCb experiment recorded in fixed-target mode is presented. The polarization of baryons is studied in colli…

A method for luminosity determination based on real-time hit reconstruction with the LHCb silicon pixel detector

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1177

The data acquisition system of the upgraded LHCb experiment includes the fast reconstruction of all hits in the vertex locator (VELO) pixel detector at the beam-crossing rate of 40…
