Description

Please find here below the FeynRules implementations of the Left-Right model.

The ​mlrsm-1.1 zip file contains the latest, complete, and fully NLO consistent implementation of the whole minimal Left-Right model.

This implementation also expresses model couplings in terms of physical parameters like particle masses and mixing angles, in the fermion as well as scalar sector.

We report here below the model physical particles:

and external input parameters with their default values:

The zip archive contains in addition:

• A number of UFO files at LO and NLO, please see ​arXiv:2403.07756 for explanations.
• Patched versions of Feynrules-2.3.49 and MoGRe_v1.1, with enhanced parallelization.
• The Mathematica and Python packages for checking perturbativity of the couplings derived from physical inputs.
