• Abstract:

  The most successful achievement in recent years in particle physics has been the discovery of the Higgs boson in 2012 at the Large Hadron Collider (LHC). So far, all measurements related with the Higgs are in good agreement with the standard model (SM) with one Higgs doublet. From theoretical arguments, it is expected that new physics addressing some of the shortcomings of the SM can indeed be at the reach of the LHC. And, at present, there are some hints pointing to possible deviations from the SM predictions. These signals will either be confirmed with upcoming data, therefore providing irrefutable signals of new physics beyond the SM) or disproved, in which case we will also learn about the possible form of new physics beyond the SM. The present proposal aims at investigating possible evidences of new physics in the framework of theoretical scenarios with extended scalar and/or lepton sectors, in the light of experimental information obtained by experiments operating at the energy and intensity frontiers, like the LHC (or future colliders) and flavour physics facilities. Besides acquiring a strong background in theoretical particle physics and a capability of designing new observables and developing new methods, the student will master several simulation and data analysis techniques. The research programme will be carried out under the supervision of F.R. Joaquim from IST and J. A. Aguilar-Saavedra from the University of Granada. Although the host institution will be IST, the candidate will spend periods of time at the University of Granada during the course of the PhD programme. The results obtained from the candidate’s research will be published in high-impact peer-review journals and presented in international scientific events.
