Abstract

We use distribution amplitudes of the light Σ\Sigma baryon and the most general form of the interpolating current for heavy Σb\Sigma_b baryon to investigate the semileptonic ΣbΣl+l\Sigma_b\rightarrow \Sigma l^+l^- transition in light cone QCD sum rules. We calculate all twelve form factors responsible for this transition and use them to evaluate the branching ratio of the considered channel. The order of branching fraction shows that this channel can be detected at LHC.
