An introduction to the minimal supersymmetric Standard Model (MSSM) is given. The motivation for “low-energy” supersymmetry is reviewed, and the structure of the MSSM is outlined. In its most general form, the MSSM can be viewed as a low-energy effective theory parametrized by a set of arbitrary soft-supersymmetry-breaking parameters. A variety of techniques for reducing the parameter freedom o...
The excluded tanβ range and Higgs boson mass regions in the framework of the Minimal Supersymmetric extension of the Standard Model (MSSM) depend on several parameters. The Higgs boson masses, cross-sections and branching fractions have been determined including two-loop diagrammatic calculations. The limits obtained with a more general scan over the parameter space of the MSSM are compared wit...
Search for Minimal Supersymmetric Standard Model Higgs bosons H/ A and for a Z boson in the τ τ final state produced in pp collisions at √ s = 13 TeV with the ATLAS Detector Abstract A search for neutral Higgs bosons of the minimal supersymmetric standard model (MSSM) and for a heavneu-tral Z boson is performed using a data sample corresponding to an integrated luminosity of 3.2 fb −1 from prot...
We provide a short account of the effects one expects on meson-antimeson oscillations in the context of the Minimal Supersymmetric Standard Model (MSSM). This issue is largely dependent on the assumptions made on the MSSM parameter space. In this respect, we consider in closer detail the cases of the general MSSM, with completely free soft terms, and the Minimal Flavor Violating limit of the MS...
We review the currently most accurate evaluation of the W boson mass, MW , in the Minimal Supersymmetric Standard Model (MSSM). It consists of a full one-loop calculation, including the complex phase dependence, all available MSSM two-loop corrections as well as the full Standard Model result. We analyse the impact of the phases in the scalar quark sector on MW and compare the prediction for MW...
We consider the leptonic and semileptonic (SL) lepton flavour violating (LFV) decays of the charged leptons in the minimal supersymmetric standard model (MSSM). The formalism for evaluation of branching fractions for the SL LFV charged-lepton decays with one or two pseudoscalar mesons, or one vector meson in the final state, is given. Previous amplitudes for the SL LFV charged-lepton decays in ...
Motivated by the di-photon excess at 750 GeV reported by the ATLAS and CMS experiments, we present an F-theory inspired flipped SO(10) model embedded in E6. The low energy spectrum includes the three MSSM chiral families, vector-like colour triplets, several pairs of charged SU(2)L singlet fields (Ec, Ēc), as well as MSSM singlets, one or more of which could contribute to the di-photon resonanc...
