Nature of problem:
The code of Monte Carlo generators often has to be tuned to the needs of large HEP Collaborations and experiments. In particular τ lepton decays need to be added (or modified) to the previously generated (or measured) events encapsulated in an event record.
The new algorithm, the universal interface of TAUOLA which works with the HepMC event record of C++ applications is documented. It uses the τ decay generator as described in  with the updates explained in . For the new interface spin treatment was improved. For example it features complete spin effects in processes mediated by Z/γ* interactions. The effects of electroweak corrections can be taken into account in this case as well. In general, the program superseeds its FORTRAN predecessor . The event record analysis as well as initialization is also modernized.
The input event record must meet the requirements described in Section 2.3.1 of the documentation.
Two sets of installation scripts; an additional tool for calculating tables for electroweak corrections.
Depends on the size and complexity of the events. Small events (<50 particles), require 1 to 7 minutes for processing 1M events on PC/Linux with a 2.4GHz processor.
