Around the 125 GeV light Higgs boson mass in the MSSM: predictions for the W boson mass
ABSTRACT: In the present work, we shall expose a general overview of the Standard Model (SM) and a brief introduction of Supersymmetry (SUSY). With these ideas, we shall set the bases on which the Minimal Supersymmetric Standard Model (MSSM) is developed. The MSSM parameter space has more than 100 f...

| Sumario: | ABSTRACT: In the present work, we shall expose a general overview of the Standard Model (SM) and a brief introduction of Supersymmetry (SUSY). With these ideas, we shall set the bases on which the Minimal Supersymmetric Standard Model (MSSM) is developed. The MSSM parameter space has more than 100 free parameters but it can be constrained according to experimental evidences. In order to do so, we shall a numerical analysis of the dependence of the mass of the Higgs boson and W boson in that supersymmetric model. First, we find ranges of free MSSM parameters that provide the mass of the light Higgs boson in the MSSM h0 about 125 GeV i.e. that are in agreement with the mass of the Higgs boson discovered by CMS and ATLAS in 2012. Afterwards, we study the effect of these free MSSM parameters in the prediction of the W boson mass mW. In particular, large dfferences between the MSSM and the SM prediction of the mass of W boson are sought in these ranges of free parameters. Finally, in agreement with these differences, we discuss how the MSSM parameter space could be constrained by (future) precision measurements of mW. |
