First measurement of the charge asymmetry in beauty-quark pair production at a hadron collider

R. Aaij, B. Adeva, M. Adinolfi +700

The difference in the angular distributions between beauty quarks and antiquarks, referred to as the charge asymmetry, is measured for the first time in $b b ˉ$ pair production…

Precision measurement of $CP$ violation in the penguin-mediated decay $B_{s}^{0} \to I ¨ I ¨ $

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1044

A flavor-tagged time-dependent angular analysis of the decay $B_{s}^{0} \to I ¨ I ¨ $ is performed using $pp$ collision data collected by the LHCb experiment at $s = 13$ TeV,…

Three-pion Bose-Einstein correlations measured in proton-proton collisions

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1128

A study on the Bose-Einstein correlations for triplets of same-sign pions is presented. The analysis is performed using proton-proton collisions at a centre-of-mass energy of $\sqr…

ChPT tests at the NA48 and NA62 experiments at CERN

NA48/2, NA62 Collaborations, : +159

The NA48/2 Collaboration at CERN has accumulated unprecedented statistics of rare kaon decays in the Ke4 modes: Ke4(+-) ( $K^{\pm} \to I ¨ ^{+} I ¨ ^{-} e^{\pm} I^½$ ) and Ke4(00) ($K^\pm \to Ï^…

Determination of f_s/f_d for 7 TeV pp collisions and a measurement of the branching fraction of the decay Bd->D-K+

LHCb Collaboration, R. Aaij, B. Adeva +548

The relative abundance of the three decay modes $B_{d} \to D^{-} K^{+}$ , $B_{d} \to D^{-} I ¨ ^{+}$ and $B_{s} \to D_{s}^{-} I ¨ ^{+}$ produced in 7 TeV $pp$ collisions at the LHC is determined from data…

Evidence for the decay $B_{s}^{0} \to K^{* 0} I^¼^{+} I^¼^{-}$

LHCb collaboration, R. Aaij, B. Adeva +788

A search for the decay $B_{s}^{0} \to K^{* 0} I^¼^{+} I^¼^{-}$ is presented using data sets corresponding to 1.0, 2.0 and 1.6 $fb^{- 1}$ of integrated luminosity co…
