The $\hat{I}{›}_c\to \hat{I}›l^{+}\hat{I}{½}_{\ell }$ weak decay including new physics

Fernando Alvarado, Luis Alvarez-Ruso, Eliecer Hernandez +2

We investigate the $\hat{I}{›}_c\to \hat{I}›{\ell }^{+}\hat{I}{½}_{\ell }$ decay with a focus on potential new physics (NP) effects in the $\ell =\hat{I}¼$ channel. We employ an effective Hamiltonian within the…
