Particle physics is a formidable endeavour to understand the four known fundamental forces: gravity, electromagnetism, weak and strong interactions. Both, theoretical and experimental efforts, represent one of the most ambitious research goals around the globe. The branches are many and the approaches quite rich. Our theory group focus mainly on the following aspects:

  • Cosmic rays
  • Precision Tests of the Standard Model
  • Effective Lagrangians for Strong and Electroweak interactions
  • Neutrino physics
  • Heavy Flavor Physics
  • Supersymmetry
  • Extra Dimensions
  • Strings

The experimental members of our group are part of the D0 and E-831 Collaborations at Fermilab, H1 Collaboration of HERA at DESY, the CMS and ALICE Collaborations at the LHC and the Pierre Auger and HAWC Collaborations for detection of ultrahigh energy cosmic rays. Some members also develop instrumentation and detector techniques with potential applications in Medical Physics.

Today the Standard Model of Particle Physics (SM) is acknowledged to be an incredible good description of particle physics processes below the electro-weak (EW) scale (around 100 GeV). In the pursue of reaffirmation as such, the particle physics community thrives to compute radiative corrections in order to propose all sorts of precision tests. Additionally, in the search of sources of physics that cannot be described by the SM, and as a way of parameterizing physics above the EW scale, Effective Lagrangians are applied to processes that may be subject to measurement in the near future in available or planned experimental facilities.
