An updated analysis of New Physics violating Lepton Flavour Universality, by using the Standard Model Effective Field Lagrangian with semileptonic dimension six operators at $\Lambda = 1\,\mathrm{TeV}$ is presented. We perform a global fit, by discus

Supersymmetric effects on heavy charged Higgs boson production in hadron colliders

The production of a heavy supersymmetric charged Higgs boson (M_{H^{\pm}}> 200 GeV) at the Tevatron and at the LHC is studied. We include the leading one-loop quantum effects within the MSSM in the relevant high \tan\beta region. Whereas the chances

Observing a heavy charged Higgs boson produced in the near future at the Tevatron or at the LHC would be instant evidence of physics beyond the Standard Model. Whether such a Higgs boson would be supersymmetric or not it could only be decided after a

Supersymmetric QCD corrections to the charged Higgs boson decay of the top quark

Autor: Jaume Guasch, Ricardo A. Jimenez, Joan Sola

Publikováno v: Physics Letters B. 360:47-56

The one-loop supersymmetric QCD quantum effects on the width of the unconventional top quark decay mode $t\rightarrow H^{+}\, b$ are evaluated within the MSSM. The study of this process is useful to hint at the supersymmetric nature of the charged Hi

Production of single top-quark final states at the LHC from supersymmetric FCNC interactions

Autor: Joan Sola, Jaume Guasch, David Lopez-Val

Publikováno v: Scopus-Elsevier

We discuss the production of single top-quark final states by direct supersymmetric flavor-changing interactions at the LHC. The total cross section pp(gg)->t\bar{c}+\bar{t}c is computed at the 1-loop order within the unconstrained MSSM. We prove tha
