Form Factors and Decay Rates for Heavy $\Lambda$ Semileptonic Decays from QCD Sum Rules

R. S. Marques de Carvalho, F. S. Navarra, M. Nielsen +2

QCD sum rules for the determination of form factors of ${\Lambda }_b$ and ${\Lambda }_c$ semileptonic decays are investigated. With a form for the baryonic current appropriate for the limits of the…
