In this work, we focus on interactions with the primordial plasma, particularly scattering processes involving particles in the early Universe, that could affect the efficiency of this mechanism. These interactions can induce decoherence in neutral B-meson oscillations, potentially suppressing baryogenesis before the mechanism reaches the temperature window in which it is most efficient. We also investigate the constraints imposed by Big Bang nucleosynthesis (BBN) on the viability of this scenario.
