Radiative decays of polarized Λb baryons represent an attractive possibility to measure the helicity of the photon emitted in the b → sγ quark transition and thus to subject the Standard Model to a stringent test at existing and future hadron colliders. The most abundant mode, Λ(1116)γ, is experimentally very challenging because of the long decay length of the Λ(1116). We show that the experime...
