Workshop on radiative leptonic B decays

28 févr. 2024, 14:00 → 1 mars 2024, 13:30 Europe/Paris

Hexagon Amphitheatre (Campus de Luminy)

Due to increasing interest in both the theoretical and experimental community, we are organising a workshop on radiative leptonic B decays in Marseille the 28th February to 1st March 2024. This will be an opportunity to unite the LHCb, Belle-II and theoretical teams working on the subject. The programme will consist of theoretical and experimental talks and discussions on charged B⁺ to ɣℓν and ℓℓℓ'ν and neutral B_s to ɣℓℓ and ℓℓℓ'ℓ'.

The workshop will be held at the amphitheatre of the Hexagon, the University library at the Luminy campus, starting at 2pm on the 28th February and finishing by midday on the 1st March. Lunch will be provided on the 29th and the same evening an informal workshop dinner will be organised at the restaurant Sepia. We will have a limited number of talks to leave sufficient room for discussion, so if you would like to give a talk please contact the organisers as soon as possible.

The organizers are grateful for the financial support from the University of Milan-Bicocca, the network GDR Intensity Frontier and the Institute of the physics of the Universe (IPhU).
