The implementation of this model is based on a work in collaboration with Genevieve Bélanger, Aoife Bharucha, Andreas Goudelis, Jan Heisige, Adil Jueid, Andre Lessa, Kirtimaan A. Mohan, Giacomo Polesello, Priscilla Pani, Alexander Pukhov, Dipan Sengupta and José Zurita. Please cite https://arxiv.org/abs/2002.12220 and ... if you use the attached model files.
The model
This model minimally extends the Standard Model with three extra states: a scalar leptoquark, a Dirac fermion and a Majorana fermion. The
The most general and renormalizable Lagrangian invariant under SU(3)c x SU(2)L x U(1)Y is given by
This model involves, in addition to the SM parameters, 22 parameters (18 corresponding to the left-handed and right-handed LQ couplings to the SM fermions, and 1 for the LQ coupling to the dark sector in addition to 3 masses)
