Description
It is well known that thanks to its mass tau lepton provide interesting signatures of new physics at LHC experiments. It can be thought of as `detector extension'. That is why it is profitable to organize simmulations following that principle. New interface of tau decay library based on present day standard of event record C++ HepMC is now available, it features all properties of the older one, but also effect of electroweak corrections and transverse spin effects can be included that way. Program is prepared to produce statistically correlated samples where such effects like QED bremsstrahlung in decays transverse spin effects or effects of new physics, can be simultaneously taken and excluded all in a single simulated sample. New organization is oriented on functionality necessary for studies of lepton universality and for simulation of SM background in tau channels with the help of measured electron and muon data. Significant part of the code is written in C++, but other ones are left in FORTRAN. In this way, once available, upgrades with the help of new data from Belle and BaBar experiments will be straightforward.
