Description

When dealing with effective Lagrangians it is often convenient to work with a basis, i.e., a complete set of independent operators. I will present BasisGen, a Python package for the automatic generation of operator bases in a general setting: it accepts any semisimple symmetry group and fields in any of its finite dimensional irreducible representations. It takes into account integration by parts redundancy and, optionally, the use of equations of motion. BasisGen is also fast: this is achieved with an implementation based on the classical representation-theoretic methods involving roots and weights.
