Measurement of the mass difference and relative production rate of the $I^c ◯_{b}^{-}$ and $I^_{b}^{-}$ baryons

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1050

The mass difference between the $I^c ◯_{b}^{-}$ and $I^_{b}^{-}$ baryons is measured using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated lumino…

Multidifferential study of identified charged hadron distributions in $Z$ -tagged jets in proton-proton collisions at $s =$ 13 TeV

LHCb Collaboration

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged…
