Abstract

We present here a new package to automatically generate a complete library of 2 to 2 squared amplitudes at leading order in any New Physics models. The package is written in C++ and based on the MARTY software. The numerical library generated allows for the computation of relic density by embedding the algorithms of SuperIso Relic.
