${\Lambda }_b\to {\Lambda }_c^{\ast }$ at $1/m_c^2$ heavy quark order

Vigilante Di Risi, Davide Iacobacci, Francesco Sannino

We systematically compute the ${\Lambda }_b(p,s_b)\to {\Lambda }_c(2595{)}^{+}$ and ${\Lambda }_b(p,s_b)\to {\Lambda }_c(2625{)}^{+}$ form factors within the Heavy Quark Effective Theory (HQET) framework including $\math…
