Constraints on the photon polarisation in $b\to s\gamma$ transitions using $B_s^0\to \varphi e^{+}{e}^{-}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1124

An angular analysis of the $B_s^0\to \varphi e^{+}{e}^{-}$ decay is performed using the proton-proton collision dataset collected between 2011 and 2018 by the LHCb experiment, correspo…
