We present a study on the impact of scalar leptoquarks on the semileptonic decays of Lambda(b) , Sigma(b) , and Xi(b) . To this end, we calculate the differential branching ratio and lepton forward-backward asymmetry ...

We calculate the mass and residue of the heavy spin-3/2 negative-parity baryons with single heavy bottom or charm quark by use of a two-point correlation function. We use the obtained results to investigate the diagonal ...

To better understand the nature and internal structure of the exotic states discovered by many collaborations, more information on their electromagnetic properties and their strong and weak interactions with other hadrons ...

The mass and meson- current coupling of the diquark- antidiquark states with the quantum numbers J(P) = 0(+) and quark contents Z(q) = [cq] [(b) over bar (q) over bar] and Z(s) = [cs] [(b) over bar(s) over bar] are calculated ...

The charged axial-vector J (P) = 1(+) tetraquarks Z(q) = [cq][ (b) over bar(q) over bar] and Z(s) = [cs][ (b) over ar(s) over bar] with the open charm-bottom contents are studied in the diquark-antidiquark model. The masses ...

The in-medium sum rules are employed to calculate the shifts in the mass and residue as well as the calar and vector self-energies of the heavy Lambda(Q), Sigma(Q) and Xi(Q) baryons, with Q being b or c quark. The maximum ...

The ground and first excited states of the decuplet baryons are studied using the two-point QCD sum rule approach. The mass and residue of these states are computed and compared with the existing experimental data and other ...

Exploration of the resonances Z(c)(3900) and Z(4430) are performed by assuming that they are the ground state and first radial excitation of the same tetraquark with J(P) = 1(+). The mass and current coupling of the Zc(3900) ...

The masses and pole residues of the ground and first radially excited Omega(0)(c) states with spin-parities J(P) = 1/2(+), 3/2(+), as well as P-wave Omega(0)(c) with J(P) = 1/2(-), 3/27(-) are calculated by means of the ...

The mass and residue of the ground-state, as well as the first orbital and radial excitations of the heavy Omega(Q) baryons with Q being b or c quark, for both J = 1/2 and J = 3/2 are calculated by means of the QCD two-point ...
