Coupled-Channel-Induced mixing of Charmonia and Testing Possible Assignments for and
The mass spectrum and the two-body open-charm decays of the
charmonium states are studied with the coupled-channel effects taken into
account. The coupled-channel-induced mixing effects among the excited vector
charmonia are studied. Based on our calculations of the masses and the decay
widths, we find that the tension between the observed properties of
and their conventional charmonia interpretations could be
softened.Comment: 13 pages, 5 figures, 5 table

Event patterns extracted from anisotropic spectra of charged particles produced in Pb-Pb collisions at 2.76 TeV
Event patterns extracted from anisotropic spectra of charged particles
produced in lead-lead collisions at 2.76 TeV are investigated. We use an
inverse power-law resulted from the QCD calculus to describe the transverse
momentum spectrum in the hard scattering process, and a revised Erlang
distribution resulted from a multisource thermal model to describe the
transverse momentum spectrum and anisotropic flow in the soft excitation
process. The pseudorapidity distribution is described by a three-Gaussian
function which is a revision of the Landau hydrodynamic model. Thus, the event
patterns at the kinetic freeze-out are displayed by the scatter plots of the
considered particles in the three-dimensional velocity, momentum, and rapidity
spaces.Comment: 19 pages, 8 figures, The European Physical Journal A, accepte
