In connection with planned experiments devoted to investigation of semileptonic decays of beauty baryons Isgur-Wise function and observables of Λb baryon (decay rates and distributions, leptonic spectra and asymmetry parameters) are calculated in the framework of diquark model with taking into account of infrared regime for heavy quark.
