Charmed-meson scattering on nucleons in a QCD Coulomb gauge quark model
The scattering of charmed mesons on nucleons is investigated within a chiral quark model inspired on the QCD Hamiltonian in Coulomb gauge. The microscopic model incorporates a longitudinal Coulomb confining interaction ...
The charmed pentaquark Θc(3250) from QCD sum rules.
(World Scientific Publishing Company, 2014-01-22)
We study, using the QCD sum rule framework, the possible existence of a charmed pentaquark that we call Θc(3250). In the QCD side we work at leading order in αs and consider condensates up to dimension 10. The mass ...
Heavy flavor relaxation in a hadronic medium
Diffusion of hidden charm mesons in hadronic medium
(Elsevier B.V., 2016-07-01)
The drag and diffusion coefficients of a hot hadronic medium have been evaluated by using hidden charm mesons as probes. The scattering amplitudes required for the evaluation of these coefficients are calculated using an ...
