Isospin-breaking in the ππ scattering amplitude. Part I. Effects due to the pion mass difference
Abstract This is the first of a series of papers devoted to a detailed analysis of isospin-breaking effects in the ππ scattering amplitude and the vector form factor of the pion. Isospin breaking originates from the mass difference between up and down quarks and from electromagnetic effects. The lat...
