I am involved in the following research direction:

Custodial symmetry and top mass

We try to lower the bound on the first new physics states in the toy model proposed in arxiv:1009.2477 by adding extra custodial symmetry breaking term that are also require to obtain a realistic mass spectrum. The model is based on custodial and L-R symmetry in order to protect the Zbbar coupling.

Effective theory in the SM in ChPT

Computation of one loop corrections in ChPT for the nonet of pseudoscalars mesons. In particular, corrections to the Formula: 0 mixing angle and to their masses and also to the vev of Formula: 1. The last quantity could contribute to the neutron EDM.
