Investigation of Effects of New Physics in ${\Lambda }_b\to {\Lambda }_c\tau {\bar{\nu }}_{\tau }$ Decay

Xiao-Long Mu, Ying Li, Zhi-Tian Zou +1

Recent experimental results of $\mathcal{R}(D^{(\ast )})$ deviate from the standard model (SM) by $3.1\sigma$, suggesting a new physics (NP) that affects the $b\to c\tau {\bar{\nu }}_{\tau }$ transition. Moti…
