Chiral effective action with heavy quark symmetry
M. A. Nowak, M. Rho, I. Zahed
We derive an effective action combining chiral and heavy quark symmetry, using approximate bosonization techniques of QCD. We explicitly show that the heavy-quark limit is compatib…
Effects of Collective Potentials on Pion Spectra in Relativistic Heavy Ion Collisions
Volker Koch, George Bertsch
The effect of collective potentials on pion spectra in ultrarelativistic heavy ion collisions is investigated. We find the effect of these potential to be very small, too small to…
Photon production through resonance in high energy heavy ion collisions
L. Xiong, E. Shuryak, G. E. Brown
Electromagnetic radiation from excited hadronic matter is one of the best ways to study the properties of the matter. Considering various processes in the hadronic gas, Kapusta et…
On the Origin of Fermion Masses
R. Shrock
We review some recent work on nonperturbative properties of fermions and connections with chiral gauge theories. In particular, we consider one of the ultimate goals of this progra…
New Tools for Analyzing Quark Mixing
Alexander Kusenko
We present some new mathematical tools which help to derive information about the quark mass matrices directly from experimental data and to elucidate the structure of these mass m…
The Propagation of Quarks in the Spatial Direction in Hot QCD
V. Koch, E. V. Shuryak, G. E. Brown +1
The dynamics of {\it light} fermions propagating in a spatial direction at high temperatures can be described effectively by a two--dimensional Schrödinger equation with {\it heavy…
