Study of Exclusive $B\to \pi e^{+}{\nu }_e$ Decays with Hadronic Full-event-interpretation Tagging in 189.3 fb${}^{-1}$ of Belle II Data

Belle II Collaboration, F. Abudinén, I. Adachi +590

We present a reconstruction of the semileptonic decays $B^0\to {\pi }^{-}{e}^{+}{\nu }_e$ and $B^{+}\to {\pi }^0{e}^{+}{\nu }_e$ in a sample corresponding to 189.3 fb${}^{-1}$ of Belle II data, using events w…
