Diquarks and the Semi-Leptonic Decay of ${\Lambda }_b$ in the Hybrid Scheme

Peng Guo, Hong-Wei Ke, Xue-Qian Li +2

In this work we use the heavy-quark-light-diquark picture to study the semileptonic decay ${\Lambda }_b\to {\Lambda }_c+l+{\bar{\nu }}_l$ in the so-called hybrid scheme. Namely, we apply the heavy quark e…
