It’s all right(-handed neutrinos): a new W ′ model for the RD∗ $$ {R}_{D^{{}_{\left(\ast \right)}}} $$ anomaly
Abstract The measured B-meson semi-leptonic branching ratios R D and RD* $$ {R}_{D^{*}} $$ have long-standing deviations between theory and experiment. We introduce a model which explains both anomalies through a single interaction by introducing a right-handed neutrino as the missing energy particl...

| description | Abstract The measured B-meson semi-leptonic branching ratios R D and RD* $$ {R}_{D^{*}} $$ have long-standing deviations between theory and experiment. We introduce a model which explains both anomalies through a single interaction by introducing a right-handed neutrino as the missing energy particle. This interaction is mediated by a heavy charged vector boson (W ′) which couples only to right-handed quarks and leptons of the Standard Model through the mixing of these particles with new vector-like fermions. Previous W ′ models for the RD* $$ {R}_{D^{\left(*\right)}} $$ anomaly were strongly constrained from flavor changing neutral currents and direct collider searches for Z ′ → τ τ resonances. We show that relying on right-handed fermion mixing enables us to avoid these constraints, as well as other severe bounds from electroweak precision tests and neutrino mixing. |
