B anomalies and the tauphilic leptoquark model
Year: 2026
Type: article
Abstract: We suggest three scalar leptoquarks, S 1 , R ˜ 2 , and S 3 which couple exclusively to the 3rd generation of leptons to explain the B anomalies. The scalar singlet S 1 can explain R ( D (*) ), while the doublet R ˜ 2 is needed to fit the branching ratio B r ( B → K ( * ) ν ν ¯ ) via the right-handed Wilson coefficients C R ν . A strong constraint from Δ m B s requires triplet S 3 where the mixing term between S 1 and S 3 is important. Our analysis suggests subdominant C V L < 0 and dominant C S L > 0 and lepton-flavor universality violating C 9 L Q ≈ + 1 . The masses are expected to be M S 1 ∼ M R ˜ 2 < M S 3 ≲ 3 TeV, which can be probed in future colliders.
