Screened potential and quarkonia properties at high temperatures
(Springer, 2009-04-01)
We perform a quark model calculation of the quarkonia b (b) over bar and c (c) over bar spectra using smooth and sudden string breaking potentials. The screening parameter is scale dependent and can be related to an effective ...

psi ` to J/psi ratio measurements in PHENIX at RHIC
(INDIAN ASSOC CULTIVATION SCIENCE, 2011)
The ratio of the psi` over the J psi production cross section in the dielectron channel has been measured in root s = 200 GeV p + p collisions with the PHENIX detector at RHIC. The analysis is based on fitting of the ...
The J/ψΦ decay channel of the Y(4140) Molecular State
(2015-01-01)
Using the QCD sum rule approach we study the Y(4140) state assuming that it can be described by a D* sD* s molecular state with JPC = 0++ quantum numbers. We evaluate the decay width into the channel Y J/ψΦ and we find the ...
Distribution amplitudes of heavy mesons and quarkonia on the light front
(Springer, 2020-10-15)
The ladder kernel of the Bethe-Salpeter equation is amended by introducing a different flavor dependence of the dressing functions in the heavy-quark sector. Compared with earlier work this allows for the simultaneous ...
Nuclear-bound quarkonia and heavy-flavor hadrons
(Elsevier B.V., 2018-05-01)
In our quest to win a deeper understanding of how QCD actually works, the study of the binding of heavy quarkonia and heavy-flavor hadrons to atomic nuclei offers enormous promise. Modern experimental facilities such as ...
Relation between Tcc,bb and Xc,b from QCD.
(W. HaxtonHolanda do Norte, 2011-07-28)
We have studied, using double ratio of QCD (spectral) sum rules, the ratio between the masses of Tcc and
X(3872) assuming that they are respectively described by the D−D∗ and D− ¯D∗ molecular currents. We
found (within ...
