# About HepLib **HepLib** is a C++ library for computations in *High Energy Physics* with the help of **GiNaC** language which is a C++ library used to perform symbolic computations. **HepLib** combines several well-known packages to get high efficiency, including * **Fermat** to perform multivariate polynomial simplification, matrix operators, ... * **FORM** to perform *Dirac* and *Color* matrix related computations, polynomial factorization, ... * **Qgraf** to generate the Feynman aptitudes/diagrams. * **FIRE** or **KIRA** for the *IBP* reduction. Another core feature of **HepLib** is the numerical evaluation of *Master Integrals* using *Sector Decomposition* with a customizable numerical integrator including the arbitrary precision supported by **MPFR**.
