Description

We present a model-independent study of $c\to d{\mu }^{+}{\nu }_{\mu }$ transitions to search new physics in the presence of right-handed neutrinos. We have adopted the effective field theory approach for the low-energy effective Hamiltonian comprising the dimension-six operators. The New Physics Wilson coefficients are determined through a ${\chi }^2$ fit by using the Miniut package to available experimental data of leptonic $D^{+}\to \overline{\mu }\nu$ and semileptonic decays $D^0\to {\pi }^{-}\overline{\mu }\nu$, $D^{+}\to {\pi }^0\overline{\mu }\nu$, $D^0\to {\rho }^{-}\overline{\mu }\nu$, $D^{+}\to {\rho }^0\overline{\mu }\nu$. The differential decay width is derived to study the $B_c^{+}\to B_d\overline{\mu }{\nu }_{\mu }$ decay for the effect of right-handed neutrinos. We also make the predictions of $q^2$ spectra and forward-backward asymmetry ($A_{FB}$) for the mode $B_c^{+}\to B_d\overline{\mu }{\nu }_{\mu }$ to inspect the effect of the allowed new physics in $c\to d$ sector through right-handed neutrinos to motivate the future measurements.
