Measurement of lepton universality parameters in $B^{+} \to K^{+} ℓ^{+} ℓ^{-}$ and $B^{0} \to K^{* 0} ℓ^{+} ℓ^{-}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1047

A simultaneous analysis of the $B^{+} \to K^{+} ℓ^{+} ℓ^{-}$ and $B^{0} \to K^{* 0} ℓ^{+} ℓ^{-}$ decays is performed to test muon-electron universality in two ranges of the square of the di…

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…
