Almost all baryons containing a single heavy quark are discovered in experiments. The quark model predicts the existence of many baryons with double heavy quarks. Among the possible double heavy baryons, only Xi(+)(cc) and Xi(++)(cc) have been experimentally observed in LHCb. Flavor-changing neutral current (FCNC) processes represent a promising platform for precise testing of SM and looking for new physics beyond the SM. In this study, the weak decays of spin-1/2 double heavy baryons to spin3/2 single heavy baryons induced by FCNC are studied within the light cone QCD sum rules method. First, the transition form factors of Xi(0,-)(bb) -> Xi(*0,(l) over bar l)(b), Xi(0,-)(bb) -> Sigma(*0,(l) over bar l)(b), Omega(-)(bb) -> Sigma(b)*(-(l) over barl), Omega(-)(bb) -> Sigma(*0,(l) over bar l)(b) decays are calculated. Then, the corresponding decay widths are estimated using the results for the form factors.eninfo:eu-repo/semantics/openAccessConference ObjectN/AN/A314WOS:001417436200004
