Abstract Pion mass difference has been calculated in the renormalizable gauge model of Bars-Halpern-Yoshimura. It is found that the soft pion mass difference is finite in the lowest order perturbative calculation, similar to the result obtained in the unified model of Salam-Weinberg. The mass difference of Kaon has also been discussed.

The Moment

We present a general strategy aimed at generating Nf = 2+1+1 configurations with quarks at their physical mass using maximally twisted mass fermions to ensure automatic O(a) improvement, in the presence of a clover term tuned to reduce the charged to neutral pion mass difference. The target system, for the moment, is a lattice of size 643 × 128 with a lattice spacing a ~ 0:08 fm. We show preliminary results on the pion and kaon mass and decay constants.
