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. The implementation is based on well-known methods to generate and decompose representations using roots and weights, which allow for fast calculations, even with large numbers of fields and high-dimensional operators. BasisGen can also be used to do some representation-theoretic operations, such as finding the weight system of an irreducible representation from its highest weight or decomposing a tensor product of representations.}, organization = {This work has been supported by the Spanish MINECO project FPA2016-78220-C3-1-P (Fondos FEDER), the Junta de AndalucĂ­a Grant FQM101 and the Spanish MECD Grant FPU14.}, publisher = {Springer Nature}, title = {BasisGen: automatic generation of operator bases}, doi = {10.1140/epjc/s10052-019-6769-5}, author = {Criado, Juan Carlos}, }
