Deskripsi
Abstract We investigate the implications of scalar and tensor operators proposed to accommodate the hints of lepton flavor universality violation in charged-current B-meson decays. We show that these scenarios unavoidably induce chirality enhanced contributions to charged lepton magnetic moments and Yukawa couplings. By using an effective field theory approach we quantify in a model independent way the connection of the R D ∗ $$ {R}_{D^{\left(\ast \right)}} $$ anomaly with the tau g − 2 and the Higgs decay h → τ τ , which can offer an alternative to test these scenarios. Concrete New Physics models giving rise to our setup will be illustrated.
