  We use distribution amplitudes of the light $\Sigma$ baryon and the most
general form of the interpolating current for heavy $\Sigma_b$ baryon to
investigate the semileptonic $\Sigma_b\rightarrow \Sigma l^+l^-$ 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.
