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 $J/\psi \to K^{\ast \pm }{K}^{\mp }\to K^{+}{K}^{-}{\pi }^0$ and $J/\psi \to K_2(1430{)}^{\pm }{K}^{\mp }\to K^{+}{K}^{-}{\pi }^0$ decays.
