Mass and magnetic moments of the heavy flavored baryons with J=32 in light cone QCD sum rules

Magnetic moments of heavy barions in the bag model reexamined

“…We see immediately that our predictions are compatible with the light cone sum rules [29], while the agreement between nonrelativistic model predictions and light cone sum rules is not so good. The results obtained using a hypercentral model [22,23] are, as a rule, somewhere between naive nonrelativistic predictions and ours.…”

“…• Light cone QCD sum rules [27][28][29]. Care must be taken when one tries to compare various expressions and results of the calculations with earlier works because of some mess-up in the notations of primed and unprimed states for the single heavy baryons Ξ Q and Ξ Q Q ʹ Usually [1] the physical Ξ Q state is assumed to be that which contains a pair of light quarks mostly in S = 0 (antisymmetric) state |Ξ Q 〉~|[q 1 q 2 ]Q〉 where q i denotes the light and Q the heavy quarks.…”

Interpretation of the new $$\Omega _c^{0}$$ Ω c 0 states via their mass and width

“…In fact, the masses of the ground-state and radially/orbitally excited heavy baryons including the 0 c particles were calculated using the relativistic quark models [3,9,10], the QCD sum rule method [4,5,7,8,[14][15][16]21,22,24,25], the heavy-quark effective theory (HQET) [6], various quark models [11][12][13]17,18,23], and lattice simulations [19,20]. The strong couplings and transitions of the heavy flavored baryons, their magnetic moments and radiative decays also attracted interest of physicists [24][25][26][27][28][29][30][31][32][33][34]. It is worth noting that in some of these theoretical studies different assumptions were made on the structure of the heavy baryons.…”

StrongΛbNBandΛcNDvertices

“…This progress has stimulated theoretical interest on the spectroscopy of these baryons via various methods (for some of them see [1][2][3][4][5][6][7][8][9][10][11] and references therein). For a better understanding of the heavy flavor physics, it is also necessary to gain deeper insight into the radiative, strong, and weak decays of the baryons containing a heavy quark.…”
