“…The studies predict a hidden charm/bottom structure together with two or three light quarks for the tetraquark or pentaquark states newly discovered by experiments. However, there are many contradictory suggestions on the quark organizations of these states in the literature (for more information see for example [16][17][18] and references therein). Hence, we need more study on the spectroscopic and decay properties of the newly founded exotic and heavy baryonic states.…”

“…Up to now, studies of hadrons with light and one heavy quark have well covered (see for instance Refs. [18][19][20][21][22][23][24][25][26][27][28][29][30][31] and references therein) but investigations of hadrons with two or more heavy flavour quarks are still rare (see for example Refs. [32][33][34][35][36][38][39][40][41] and references therein).…”

In most non-perturbative methods in hadron physics the calculations are started with a correlation function in terms of some interpolating and transition currents in x-space. For simplicity, the calculations are then transformed to the momentum space by a Fourier transformation. To suppress the contributions of the higher states and continuum; and enhance the ground state contribution, Borel transformation as well as continuum subtraction are applied by the help of quark-hadron duality assumption. In the present study we work out the mathematics required for these processes in the case of light and multiheavy hadrons. We address a well-known problem in subtraction of the effects of the higher states and continuum and discuss how we find finite results without any divergence by using an appropriate representation of the modified Bessel functions, appearing in the heavy quark propagator, and successive applications of the Borel transformations, which lead to more suppression of the higher states and continuum contributions. The results obtained can be used in determination of the spectroscopic and decay properties of the multi-heavy standard and non-conventional (exotic) systems in many non-perturbative methods, specially the QCD sum rules. *

The magnetic dipole moments of the spin-1 2 doubly heavy baryons are extracted in the framework of light-cone QCD sum rule using the photon distribution amplitudes. The electromagnetic properties of the doubly heavy baryons encodes important information of their internal structure and geometric shape. The results for the magnetic dipole moments of doubly heavy baryons acquired in this work are compared with the predictions of the other theoretical approaches. The agreement of the estimations with some (but not all) theoretical estimations is good.

The electromagnetic multipole moments of the open-flavor Zcq states are investigated by assuming a diquark-antidiquark picture for their internal structure and quantum numbers J P C = 1 +− for their spin-parity. In particular, their magnetic and quadrupole moments are extracted in the framework of light-cone QCD sum rule by the help of the photon distribution amplitudes. The electromagnetic multipole moments of the open-flavor Zcq states are important dynamical observables, which encode valuable information on their underlying structure. The results obtained for the magnetic moments of different structures are considerably large and can be measured in future experiments. We obtain very small values for the quadrupole moments of Zcq states indicating a nonspherical charge distribution.
