Physics Beyond the Standard Model
There is reason to believe that the Standard Model (SM) of particle physics, the theory describing all particles and interactions of the subatomic realm, might have its validity limit at energies close to the TeV scale. CERN´s Large Hadron Collider (LHC) was built to explore that energy scale and has been releasing results for a few years. The scientific community has been making great effort, both on the theoretical and experimental fronts, to direct searches and understand the results produced by the LHC and other experiments that test the limits of the SM. I have been focusing on model building and phenomenology of extensions of the SM at the TeV scale.

Hadronic Spectroscopy
One of the most challenging aspects of Quantum Chromodynamics (QCD) consists in understanding its low energy regime, where confinement, whose origin and dynamics are obscure to us, has a main role. We would like to understand how quarks and gluons, the main actors of QCD, coalesce into hadrons. One of the places where we can look for clues about the inner workings of confinement is in hadronic spectroscopy. The mass spectrum of hadrons can be seen as empirical information on the relevant degrees of freedom and has been used for the construction of many models. I have been interested in heavy states recently discovered in this spectrum and whose structure is still under dispute, the so called “exotic states” which are not easily described as usual baryons or mesons. The main tool used so far is the QCD Sum Rules (QCDSR), a well known method of non-perturbative QCD calculation.
