The ${\Lambda }_c\to \Lambda l^{+}{\nu }_{\ell }$ weak decay including new physics

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

We investigate the ${\Lambda }_c\to \Lambda {\ell }^{+}{\nu }_{\ell }$ decay with a focus on potential new physics (NP) effects in the $\ell =\mu$ channel. We employ an effective Hamiltonian within the fram…
