Abstract
The first search for the rare radiative decay $\Xi_b^- \to \Xi^- \gamma$ 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 $\Xi_b- \to \Xi^- J/\psi$ channel is used as
normalization. No $\Xi_b^- \to \Xi^- \gamma$ signal is found and an upper limit
of $\mathcal{B}(\Xi_b^- \to \Xi^- \gamma) < 1.3 \times 10^{-4}$ at 95%
confidence level is obtained.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported. We recognise the importance of recommender services in supporting research discovery and are evaluating offerings from other service providers.
