Implementation of scalar and vector resonances into FeynRules and LanHEP

Description

In this summary report we discuss the implementation of a set of operators in FEYNRULES and LANHEP that can be used to study in a bottom-up approach new scalar and vector resonances coupling to quarks. The outline of this contribution is as follows: In Section 2 we review the operators and the spectrum of the resonances we implemented. In Sections 3 and 4 we discuss the implementation of all these operators into the FEYNRULES and LANHEP packages. We compare the two implementations in Section 5 by computing a selection of decay rates and 2-to-2 cross section with MADGRAPH 5 and CALCHEP. The set of operators is relevant to study in a bottom-up approach the possible BSM contributions to the anomaly in the forward-backward asymmetry in top pair production measured by the CDF and DO experiments. The implementation was done in a modular way, allowing the user to decide which resonances to consider, and gives the possibility to include all possible flavor and or CP-violating effects
