Branching ratio estimates of τ− → π−η(′)vτ decays
We study the rare τ− → π− η(′)vτ decays. These processes occur via isospin violation and belong to the so-called second-class currents unseen in Nature so far. Our analysis is based on the framework of resonance chiral theory supplemented by dispersion relations. In this contribution we discuss the...
