Measurement of the $K^{\pm} \to \pi^{+}\pi^{-}e^{\pm} \overset{(-)}{\nu_{e}}$ form factors and of the $\pi \pi$ scattering length $a^{0}_{0}$

The quark condensate is a fundamental free parameter of Chiral Perturbation Theory (PT), since it determines the relative size of the mass and momentum terms in the power expansion. In order to confirm or contradict the assumption of a large quark condensate, on which PT is based, experimental tests...
