Measurement of the branching fraction of the $I^_{b}^{0} \to J / I ¨ I^$ decay and isospin asymmetry of $B \to J / I ¨ K$ decays

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

This paper describes a measurement of the $I^_{b}^{0} \to J / I ¨ I^$ branching fraction using data collected with the LHCb experiment in proton-proton collisions from 2016 to 2018. The dat…

Measurement of the Lund plane for light- and beauty-quark jets

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1136

The substructure of jets in quantum chromodynamics (QCD) has garnered significant attention with the advent of infrared- and collinear-safe clustering algorithms and observables. A…

Search for low-mass dijet resonances using trigger-level jets with the ATLAS detector in $pp$ collisions at $s = 13$ TeV

ATLAS Collaboration

Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-…
