Width of exotics from QCD sum rules : tetraquarks or molecules?
Su Houng Lee, Kenji Morita, Marina Nielsen
We investigate the widths of the recently observed charmonium like resonances X(3872), Z(4430) and Z_2(4250) using QCD sum rules. Extending previous analyses regarding these states…
Properties of Quarkonia at T_c
Su Houng Lee, Kenji Morita
We discuss how the spectral changes of quarkonia at T_c can reflect the ``critical'' behaviour of QCD phase transition. Starting from the temperature dependencies of the energy den…
Critical behavior of charmonia across the phase transition: A QCD sum rule approach
Kenji Morita, Su Houng Lee
We investigate medium-induced change of mass and width of J/psi and eta_c across the phase transition in hot gluonic matter using QCD sum rules. In the QCD sum rule approach, the m…
Mass Shift and Width Broadening of J/psi in hot gluonic plasma from QCD Sum Rules
Kenji Morita, Su Houng Lee
We investigate possible mass shift and width broadening of J/psi in hot gluonic matter using QCD sum rule. Input values of gluon condensates at finite temperature are extracted fro…
