$K\to3\pi$ Decays in Chiral Perturbation Theory
Johan Bijnens, Pierre Dhonte, Fredrik Persson
The CP conserving amplitudes for the decays $K\to3\pi$ are
calculated in Chiral Perturbation Theory at the next-to-leading order.
We present the expressions in a compact form with single parameter
functions only. These expressions are then fitted to all available
$K\to2\pi$ and $K\to3\pi$ data to obtain a fit of the parameters that
occur. We compare with the work of Kambor, Missimer and Wyler.
