Isospin breaking in K -> 3 pi decays I: strong isospin breaking

Research output: Contribution to journal › Article › peer-review

Abstract

The CP conserving amplitudes for the decays K --> 3pi are calculated in Chiral Perturbation Theory. The calculation is made at the next-to-leading order including strong and local electromagnetic isospin breaking. A comparison is made between the squared amplitudes with and without isospin violation to estimate the size of the effect. We find corrections of order five percent in the amplitudes.
