Evidence for $B^-\rightarrow D^{**0}\tau^-\overline{\nu}_{\tau}$ decays / LHCb Collaboration
The first evidence for the decay $B^-\rightarrow D^{**0}\tau^-\overline{\nu}_{\tau}$ is obtained using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb$^{-1}$ , at centre-of-mass energies of 7, 8 and 13 Tev. Here, the $D^{**0}$ meson represents any of the three excited charm mesons $D_{1}(2420)^{0}$, $D_{2}^{*}(2460)^{0}$, and $D_{1}^{'}(2400)^{0}$. [...]
