Semileptonic Decays of Heavy Baryons

Semileptonic decays of heavy baryons are studied within the relativistic quark model based on the quasi-potential approach and quantum chromodynamics. Form factors parametrizing the matrix elements of weak transitions are calculated in the entire available kinematic interval with consistent consideration of relativistic effects. The results on the probabilities of semileptonic decays and other observable quantities are in good agreement with the available experimental data.
