Algorithms of Bd0 effective mass determination in investigation of CP-violation

New methods for calculation of a mass of J/Ψ and KS0 necessery for determination of Bd0 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 KS0 events (noncomplete topology case) is presented, this method reconstructs vertex coordinates and kinematic parameters of pions in KS0 decays concurently. The precision of calculation of a mass of Bd0 - 117 MeV, J/Ψ -286 MeV, Ks0 (complete topology) - 9 MeV, KS0 (noncomplete topology) - 14 MeV. 16 refs.; 8 figs
