Abstract: We explore a scenario in which strong gravity could be responsible for modifying the cross sections of leptons produced in semi-leptonic B meson decays, thus breaking lepton universality. This is achieved by considering the effect of long-range interactions on the scattering cross section of particles, which is referred to as the Sommerfeld factor. We also place upper limits on strong gravity based on its potential contribution to the measured cross-section of W bosons near the production threshold. Strong gravity is parameterized with a Yukawa potential reproducing usual gravity in the macroscopic world, but with much stronger coupling at short distances.

Advisor: Professor Roberto Onofrio
