Radiative corrections to the Dalitz plot of Kl30 decays

A model-independent expression for the Dalitz plot of semileptonic decays of neutral kaons, Kl30, including radiative corrections to order (α/π)(q/M1), where q is the momentum transfer and M1 is the mass of the kaon, is presented. The model dependence of radiative corrections is kept in a general form within this approximation, which is suitable for model-independent experimental analyses. Expressions for bremsstrahlung radiative corrections are presented in two forms: one with the triple integral over the kinematical variables of the photon ready to be performed numerically and the other one in a fully analytical form. The final result is restricted to the so-called three-body region of the Dalitz plot and it is not compromised to fixing the values of the form factors at predetermined values. © 2015 American Physical Society. © 2015 American Physical Society.
