$B_c\to D^{(\ast )}\tau {\bar{\nu }}_{\tau }$ processes in an effective field theory approach

Anupama Bhol, Suchismita Sahoo, Soram Robertson Singh

We present a compressive study on rare semileptonic $B_c\to D^{(\ast )}\tau {\bar{\nu }}_{\tau }$ decays involving $b\to u\tau {\bar{\nu }}_{\tau }$ quark level transitions in an effective field theory approach. W…
