Research on the electromagnetic and weak dipole moments of the tau-lepton at the Bestest Little Higgs Model

Abstract

AbstractIn this paper, using the Bestest Little Higgs Model (BLHM) we calculate at the one-loop level the contributions to the Anomalous Magnetic Dipole Moment (AMDM) and Anomalous Weak Magnetic Dipole Moment (AWMDM) of the tau-lepton. The implications from this model are studied, emphasizing the contributions of the new physics induced by the new scalar and vector bosons of the BLHM: $$S_i=H_0, A_0, \phi ^{0}, \eta ^{0}, \sigma , H^{\pm }, \phi ^{\pm }, \eta ^{\pm }$$ S i = H 0 , A 0 , ϕ 0 , η 0 , σ , H ± , ϕ ± , η ± , and $$V_i=Z', W'^{\pm }$$ V i = Z ′ , W ′ ± because these quantify the new physics. With these new contributions, we estimated bounds on the real and imaginary parts of the AMDM and AWMDM of the tau-lepton. Our study complements other one-loop-level research performed on models beyond the Standard Model.
