A QCD Sum Rule Approach to the Charmonium - Pion Cross Section
In relativistic heavy ion collisions J/ψ suppression has been recognized as an important tool to identify the possible phase transition to quark-gluon plasma (QGP). Matsui and Satz [1] predicted that in presence of quark-gluon plasma, binding of a cc̄ pair into a J/ψ meson will be hindered, leading to the so called J/ψ suppression in heavy ion collisions. Over the years several experiments measu...
متن کاملChiral Symmetry and Finite Pion Mean Field in Nuclei
We start with the discussion of the recent ab initio variational calculations of light nuclei up to the mass number A ≤ 10 of the Argonne-Illinois group [1]. They take the two nucleon interaction obtained from the scattering data and add the three body interaction so as to reproduce the binding energies of the three nucleon systems. They reproduce very nicely the light nuclei including the exci...
متن کاملIn-medium Pion and Partial Restoration of Chiral Symmetry
The partial restoration of chiral symmetry in nuclear medium is investigated in a model independent way by exploiting operator relations in QCD. An exact sum rule is derived for the quark condensate valid for all density. This sum rule is simplified at low density to a new relation 〈q̄q〉∗/〈q̄q〉 = (F t π/Fπ)Z ∗1/2 π with the in-medium quark condensate 〈q̄q〉 ∗, in-medium pion decay constant F t π an...
متن کاملCharmonium-Hadron Cross Section in a Nonperturbative QCD Approach
We calculate the nonperturbative J/Ψ−N and Ψ′−N cross sections with the model of the stochastic vacuum which has been succesfully applied in many high energy reactions. We also give a quantitative discussion of pre-resonance formation and medium effects. PACS: 13.85.Hd 13.85.Ni 13.87.Fh 14.65.Dw 14.40.Lb During the next year the first data on heavy ion collisions at high energy ( √ s = 200 GeV ...
متن کاملChiral symmetry and pion condensation. II. General formalism
The role of chiral symmetry in pion condensation was explored through model calculations in the preceding paper. Here we present model-independent results which justify and sometimes go beyond the previous work. Our methods are based on functional techniques used in field theory. The paper is not self-contained and is meant to be read in conjunction with the preceding one. In the course of this...
