Search for rare B Meson Decay and Missing Energy at Belle II

Abstract

B-Mesogenesis is a model proposed to simultaneously explain Baryogenesis and Dark mat ter. CP violation in the B meson system and rare decays in the early Universe can simultaneously explain the matter anti-matter asymmetry and dark matter in our Universe This thesis is a search for B meson decay into 2 baryon and yox, a new dark anti-baryon. We generate events, simulate detector responses and reconstruct the particle decay using various software at Belle II.
