| heal.abstract | This thesis presents a measurement of specific branching functions for the decay of the B0 meson. The blinded measurement of the relative branching ratio đ đž0đ(đ) of the đĩ0 â đđđž0đ Flavor Changing Neutral Current (FCNC) decay with respect to the tree-level resonant decay đĩ0 â đŊ/đ(đđ)đž0đ , as well as the tree-level decay đĩ0 â đ(2đ) (đđ)đž0đ relative to the tree-level decay đĩ0 â đŊ/đ(đđ)đž0đ is also measured. FCNC processes are forbidden at tree-level in the Standard Model with branching functions at the order of magnitude of 10^â7 compared to resonant tree-level processes at the order of magnitude of 10^â4. FCNC decays are an important aspect in searching for New Physics beyond the Standard Model whose effects can affect the value of the đ đž0đ(đ) observable that is measured in this thesis. The data provided for the analysis of this thesis have been recorded by the CMS experiment at CERN LHC during Run 3 at 2022 with center of mass energy âđ = 13.4TeV and nominal integrated luminosity of L = 39.7 đđ^â1. This analysis is part of a bigger ongoing project which aims to probe Lepton Flavor Universality by studying đ â đ đ transitions at the CMS experiment at CERN LHC. | en |
