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