Study of charm mixing and CP violation with $D^{0} \to K^{\pm} π^{\mp} π^{\pm} π^{\mp}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1188

A study of charm mixing and CP violation in $D^{0} \to K^{\pm} π^{\mp} π^{\pm} π^{\mp}$ decays is performed using data collected by the LHCb experiment in proton-proton collisions from 2015 to 2…

Inclusive $B$ -meson flavour-tagging algorithm at LHCb

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1179

A new algorithm is developed to identify the flavour of neutral $B$ mesons at production in $pp$ collisions by utilising all tracks from the hadronisation process. The algorithm is…

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/ $c$ . This is achie…

Measurement of transverse $Λ$ and $Λ ˉ$ hyperon polarization in $p$ Pb collisions at $s_{N N} = 5.02$ TeV

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1131

The transverse polarization of $Λ$ and $Λ ˉ$ hyperons is measured in $p$ Pb collisions collected by the LHCb experiment at a nucleon-nucleon center-of-mass energy of $5.02$ TeV. T…
