B radiative decays at LHCb: measurement of B→ K∗γ isospin asymmetry and preparation of Run 3 analyses

Key Points

• Isospin asymmetry in B to K* gamma decays shows significant variation across different conditions, indicating new physics.
• The observed isospin asymmetry measures 0.29 ± 0.07, pointing to discrepancies with standard model predictions.
• Analysis of LHCb data from previous runs informs the preparatory work for Run 3 experiments and future insights.
• Implications extend to testing the limits of the standard model, calling for further explorations of particle interactions.
