Axial Vector Current and Coupling of the Quark in the Instanton Model
G. W. Carter
We compute the axial vector current, form factor, and coupling for quarks in the instanton liquid model with two light flavors. Non-local current corrections are derived, as requir…
Forced Tunneling and Turning State Explosion in Pure Yang-Mills Theory
D. M. Ostrovsky, G. W. Carter, E. V. Shuryak
We consider forced tunneling in QCD, described semiclassically by instanton-antiinstanton field configurations. By separating topologically different minima we obtain details of th…
Instanton-induced Semi-hard Parton Interactions and Phenomenology of High Energy Hadron Collisions
G. W. Carter, D. M. Ostrovsky, E. V. Shuryak
We phenomenologically study whether partonic collisions responsible for the growth of hadron-hadron cross sections at high energy can be ascribed to instanton-induced processes. Al…
Color Superconductivity and Blinking Proto-Neutron Stars
G. W. Carter
If quark matter exists in the cores of neutron stars, it is most likely color superconducting. Thus a phase transition from free to paired quark matter might occur during the first…
Do Instantons and Strings Cluster when the Number of Colors is Large?
G. W. Carter, E. V. Shuryak
We consider the limit of QCD using a toy model in which instantons exchange color-singlet scalar fields which do not self-interact. Our main observation is that coll…
Neutrino Propagation In Color Superconducting Quark Matter
Gregory W. Carter, Sanjay Reddy
We calculate the neutrino mean free path in color superconducting quark matter, and employ it to study the cooling of matter via neutrino diffusion in the superconducting phase as…
The Nonperturbative Color Meissner Effect in a Two-Flavor Color Superconductor
G. W. Carter, D. Diakonov
Color superconductivity in QCD breaks the SU(3) color gauge group down to SU(2), inducing masses in five of the eight gluons. This is a dynamical Higgs effect, in which the diquark…
Instanton-Induced Interactions in Finite Density QCD
G. W. Carter, D. Diakonov
We consider the finite density, zero-temperature behaviour of quark matter in the instanton picture. Since the instanton-induced interactions are attractive in both and…
Chiral Symmetry Breaking and Color Superconductivity in the Instanton Picture
Gregory W. Carter, Dmitri Diakonov
The instanton approach to spontaneous chiral symmetry breaking is reviewed, with emphasis on the connection to chiral random matrix theory. We extend the approach to discuss the fi…
Finding the Pion in the Chiral Random Matrix Vacuum
G. W. Carter, A. D. Jackson
The existence of a Goldstone boson is demonstrated in chiral random matrix theory. After determining the effective coupling and calculating the scalar and pseudoscalar propagators,…
Light Quarks in the Instanton Vacuum at Finite Baryon Density
G. W. Carter, D. Diakonov
We consider the finite density, zero-temperature behaviour of quark matter in the instanton picture. Since the instanton-induced interactions are attractive in both and…
Towards a Theory of Instantons at Non-zero Fermion Density
Gregory W. Carter, Dmitri Diakonov
A formalism to study light fermions at non-zero chemical potential in the instanton medium is presented. It is then applied to investigate chiral symmetry restoration and diquark c…
