Polarized ${\Lambda }_b\to {\Lambda }_{c}l\bar{\nu }$ decay in perturbative QCD

Hsien-Hung Shih, Shih-Chang Lee, Hsiang-nan Li

We study the polarized ${\Lambda }_b$ baryon semileptonic decay ${\Lambda }_b\to {\Lambda }_{c}l\bar{\nu }$ using perturbative QCD factorization theorem. In this approach heavy baryon transition form factors are…
