The LHCb upgrade I

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1305

The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger th…

Measurement of $C P$ -averaged observables in the $B^{0} \to K^{* 0} μ^{+} μ^{-}$ decay

LHCb collaboration, R. Aaij, C. Abellán Beteta +902

An angular analysis of the $B^{0} \to K^{* 0} (\to K^{+} π^{-}) μ^{+} μ^{-}$ decay is presented using a data set corresponding to an integrated luminosity of 4.7 fb $^{- 1}$ of $pp…

Measurement of charged hadron production in $Z$ -tagged jets in proton-proton collisions at $s = 8$ TeV

LHCb Collaboration, R. Aaij, C. Abellán Beteta +851

The production of charged hadrons within jets recoiling against a $Z$ boson is measured in proton-proton collision data at $s = 8$ TeV recorded by the LHCb experiment. The cha…

Measurements of $C P$ asymmetries in charmless four-body $Λ_{b}$ and $Ξ_{b}^{0}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +841

A search for $C P$ violation in charmless four-body decays of $Λ_{b}$ and $Ξ_{b}^{0}$ baryons with a proton and three charged mesons in the final state is performed. To cancel out product…

LHCb Collaboration, R. Aaij, C. Abellán Beteta +843

The production fractions of $B_{s}^{0}$ and $Λ_{b}^{0}$ hadrons, normalized to the sum of $B^{-}$ and $B^{0}$ fractions, are measured in 13 TeV pp collisions using data c…
