Qualitons At High Density
In the color-flavor-locked (CFL) phase of the QCD superconductor we show that baryons behave as qualitons (called “superqualitons”) with quantum numbers B = (1 mod 2)/3, S = 1/2 and Y = B. Bound superqualitons may cause the superconducting gap in the CFL phase to be effectively nonexistent, a novel phenomenon not seen in conventional superconductors.

متن کاملQualitons from QCD
Qualitons, topological excitations with the quantum numbers of quarks, may provide an accurate description of what is meant by constituent quarks in QCD. Their existence hinges crucially on an effective Lagrangian description of QCD in which a pseudoscalar colour-octet of fields enters as a new variable. We show here how such new fields may be extracted from the fundamental QCD Lagrangian using...
متن کاملQCD at High Parton Density
The high parton density regime in deep inelastic electronproton (nucleus) scattering is characterized by small values of the Bjorken variable x = Q/s, where Q is the momentum transfer and √ s is the center of mass energy, and represents the challenge of studying the interface between the perturbative and nonperturbative QCD, with the peculiar feature that this transition is taken in a kinematic...
متن کاملQCD at high density/temperature
QCD now occupies an established position as the well-attested theory of strong-interaction physics. Other contributions to these proceedings (those of S. Frixione, L. Lellouch, and K. Long) survey the agreement between evidence from particle collider experiments and perturbative and lattice QCD calculations. However, there is more to QCD than collisions between pairs of particles. QCD should al...
متن کاملMixing at High Temperature and Density
The temperature and density dependence of the ρ − ω mixing amplitude has been studied from a purely hadronic model. The in-medium baryon masses and chemical potentials have been obtained at the Mean Field (MF) Level and these results have been used to calculate the mixing amplitude. It has been observed that the mixing amplitude changes substantially at high temperature and density. Charge Symm...
