KORALB — an upgrade to version 2.4

Abstract
An upgrade of the Monte Carlo program for τ pair production including τ mass, spin and QED O(α) effects is presented. Its main feature is the interface to the new τ decay Monte Carlo library TAUOLA, new coding of the final states and implementation of the Z exchange at the Born level.

Title of program: KORALB, version: 2.4
Catalogue Id: AABH_v3_0 [ACVS]

Nature of problem
Comparison with the previous version and reasons for the new version The tau decay library [2] is now updated. The physics content of the tau production part of the program is enriched. Convenient for certain tests, the possibility to use the program at the Born level including Z exchange is introduced.
