Scalar quarkonia at finite temperature
(American Physical Society, 2010-09-28)
Masses and decay constants of the scalar quarkonia, chi(Q0)(Q = b, c) with quantum numbers I-G (J(PC)) = 0(+)(0(++)), are calculated in the framework of the QCD sum rules approach both in vacuum and finite temperature. The ...
Radial excitations of the decuplet baryons
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 ...
