The aim is to construct simplified models for EW spin-1 resonances arising from strongly-coupled EWSB dynamics which can be used by the experimental collaborations to report their results.
Quantum numbers considered: rhoL (3,1) ; rhoR (1,3) of SO(4)~SU(2)_L x SU(2)_R
Models
We will consider two simplified models, corresponding to two broad interesting theoretical scenarios:
(A) Model with universal rho couplings to SM fermions (through A-rho mixing) + direct couplings to top/bottom Parameters: { grho (L/R), mrho (L/R), g_top }
(B) Model with MFV fermion couplings Parameters: { grho (L/R), mrho (L/R), theta_u , theta_d }
Tasks
1) Rotating the Lagrangian into mass eigestate basis (expanding in powers of H/f) [ Roberto C., C. Grojean, Jamison G., Veronica S., Andreas W. … ]
Notes on rotation for model (A)
2) Implementation of the models into FeynRules [ Veronica S., Andreas W. … ]
3) Derive combined bounds from the existing searches (ll, lnu, VV, Vh, tt, tb) + EWPT [ Gustaaf B., R. Rosenfeld … ]
4) Mapping into popular models [ Seung L. … ]
5) Extensions (e.g. SO(6)) [ Aldo D. … ]
6) Implementation in CalcHEP [ R. Rosenfeld … ]
