Abstract

The first search for the rare radiative decay Ξ−b → Ξ−γ is performed using data collected by the LHCb experiment in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb−1. The Ξ−b → Ξ−J/ψ channel is used as normalization. No Ξ−
b → Ξ−γ signal is found and an upper limit of B(Ξ−b → Ξ−γ) < 1.3 × 10−4 at 95% confidence level is obtained.
