Measurement of the charge asymmetry in $B^{\pm }\to \varphi K^{\pm }$ and search for $B^{\pm }\to \varphi {\pi }^{\pm }$ decays

LHCb collaboration, R. Aaij, B. Adeva +655

The \CP-violating charge asymmetry in $B^{\pm }\to \varphi K^{\pm }$ decays is measured in a sample of $pp$ collisions at 7 TeV centre-of-mass energy, corresponding to an integrated…
