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…
In-medium modification of P-wave charmonia from QCD sum rules
Young-Ho Song, Su Houng Lee, Kenji Morita
We investigate the changes of the masses and widths of and in hot gluonic matter near and in nuclear medium using QCD sum rules. As in the previous works fo…
Can the resonance structures be and molecules?
Su Houng Lee, Kenji Morita, Marina Nielsen
We use QCD sum rules to study the recently observed resonance-like structures in the mass distribution, and , considered as $D^{*+}\bar{D}^{*…
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…
Properties of at : QCD second-order Stark effect
Su Houng Lee, Kenji Morita
Starting from the temperature dependence of the energy density and pressure from lattice QCD calculation, we extract the temperature dependence of the electric and magnetic condens…
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…
