Observation of new baryons in the $I^_{b}^{-} I ¨ ^{+} I ¨ ^{-}$ and $I^_{b}^{0} I ¨ ^{+} I ¨ ^{-}$ systems

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1052

The first observation and study of two new baryonic structures in the final state $I^_{b}^{0} I ¨ ^{+} I ¨ ^{-}$ and the confirmation of the $I^_{b} (6100)^{-}$ state in the $I^_{b}^{-} I ¨ ^{+} I ¨ ^{-}$ decay mo…

Observation of a $J / I ¨ I^$ resonance consistent with a strange pentaquark candidate in $B^{-} \to J / I ¨ I^ p ˉ$ decays

LHCb collaboration

An amplitude analysis of $B^{-} \to J / I ¨ I^ p ˉ$ decays is performed using about 4400 signal candidates selected on a data sample of $pp$ collisions recorded at center-of-mass energ…

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…

Measurement of the ratios of branching fractions $R (D^{*})$ and $R (D^{0})$

LHCb Collaboration

The ratios of branching fractions $R (D^{*}) \equiv B (B ˉ \to D^{*} I ¨ ^{-} I^ˉ ½_{I ¨} ) / B (B ˉ \to D^{*} I^¼^{-} I^ˉ ½_{I^} ¼)$ and $\mathcal{R}(D^{0})\equiv\…
