Probing the nature of the state using radiative decays
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1097
The radiative decays and are used to probe the~nature of the~ state using proton-proton collisio…
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…
Coherent photoproduction of and excited vector mesons in ultraperipheral PbPb collisions
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1132
The invariant-mass distribution for the coherent photoproduction of dipions in ultraperipheral PbPb collisions is measured using data, corresponding to an integrated luminosity of…
Deuteron identification via time of flight with LHCb
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1183
It is shown that the timing capabilities of the LHCb detector operated during the LHC Run 2 can be used to identify light ion particles with momenta of a few GeV/. This is achie…
First measurement of -jet mass with and without grooming
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1138
The LHCb collaboration presents a novel suite of heavy-flavour jet substructure measurements at forward rapidity in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}…
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…
