Search of decays of the Higgs Boson into Muons in p-p collisions with CMS detector

The H$\rightarrow\mu^+\mu^-$ branching fraction is very small ($2.4\times10^{-4}$) however it is very important because it involves fermionic coupling (Yukawa coupling), and the mass of the final state fermions is small, which allows to study the dependence of the Higgs couplings on the mass of the different states. Therefore in the experimental studies of the Higgs properties being able to observe H$\rightarrow\mu^+\mu^-$ and measure the branching fraction is a necessary step. For the second run of the LHC, the CMS collaboration has made an emphasis on this an other similar channels. For my dissertation I have focused on the search of H$\rightarrow\mu^+\mu^-$ events, and specially in the optimization of the search through the recovery of events lost due to the emission of photons by the muons (final state radiation, FSR). In this thesis I present results of the methods that I have implemented to recover Higgs events (FSR Recovery) and the latest results of the CMS search of the evidences of the H$\rightarrow\mu^+\mu^-$ decay.\\
