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 ...
1(--) and 0(++) heavy four-quark and molecule states in QCD
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We estimate the masses of the 1(--) heavy four-quark and molecule states by combining exponential Laplace (LSR) and finite energy (FESR) sum rules known perturbatively to lowest order (LO) in alpha(s) but including ...
Dynamical gluon mass corrections in heavy quarkonia decays

Dynamical gluon mass corrections in heavy quarkonia decays
(Elsevier B.V., 2000-06-08)
Using the expression of the dynamical gluon mass obtained through the operator product expansion we discuss the relevance of gluon mass effects in the decays V --> hadrons (V = J/psi, Y), Relativistic and radiative corrections ...

Description of Heavy Quark Mass by Lippmann-Schwinger Equation
(Springer/plenum Publishers, 2012-09-01)
Quark masses are of great prominence in high-energy physics. In this paper, we have studied the heavy meson systems via solving the Lippmann-Schwinger equation by using the Martin potential for heavy quark masses. We have ...
