Chiral Perturbation Theory Predictions for $η \to π^{+} π^{-} π^{0} γ$

A. Bramon, P. Gosdzinsky, S. Tortosa

The $η \to π^{+} π^{-} π^{0} γ$ decay is discussed in the general context of Chiral Perturbation Theory (ChPT), assuming that the low--energy constants (counter--terms) are saturated by v…

Residual long-range pseudoscalar forces between unpolarised macroscopic bodies

J. A. Grifols, S. Tortosa

In this paper we survey the effects of residual long-range forces associated to $γ_{5}$ -spin dependent-couplings of fermions to massless bosons exerted by unpolarised bulk matter ove…
