Abstract

New methods for calculation of a mass of J/{Psi} and K{sub S}{sup 0} necessery for determination of B{sub d}{sup 0} mass in a new approach to the measurement of CP-violation in B decays are presented. These methods have high speed of calculation and can be adapted simply for a new condition of experiment and can be applied for a set-up with complicated magnetic fields. A new method for analysis of K{sub S}{sup 0} events (noncomplete topology case) is presented, this method reconstructs vertex coordinates and kinematic parameters of pions in K{sub S}{sup 0} decays concurently. The precision of calculation of a mass of B{sub d}{sup 0} - 117 MeV, J/{Psi} -286 MeV, K{sub s}{sup 0} (complete topology) - 9 MeV, K{sub S}{sup 0} (noncomplete topology) - 14 MeV. 16 refs.; 8 figs.
