Detector resolution correction for width of intermediate states in three particle decays

Abstract

We propose a method that allows to take into account detector resolution in the partial wave analysis event-by-event fit as a special case. Implementation of the method is discussed and the applicability of the method is studied for the $J/\psi \to K^{*\pm}K^{\mp} \to K^+K^-\pi^0$ and $J/\psi \to K_2(1430)^\pm K^{\mp} \to K^+K^-\pi^0$ decays.
