Corrections to the Nuclear Axial Vector Coupling in a Nuclear Medium

G. W. Carter, E. M. Henley

We examine further corrections to the time component of the axial vector coupling constant in a nuclear medium. The dominant correction is that of exchange currents. The correction…

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…

The Quenching of the Axial Coupling in Nuclear and Neutron-Star Matter

G. W. Carter, M. Prakash

Using a chirally invariant effective Lagrangian, we calculate the density and isospin dependences of the in-medium axial coupling, , in spatially uniform matter present in c…

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,…

An Effective Model for Hot Gluodynamics

G. W. Carter, O. Scavenius, I. N. Mishustin +1

We consider an effective Lagrangian containing contributions from glueball and gluon degrees of freedom with a scale-invariant coupling between the two. The thermodynamic potential…

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…

An Effective Lagrangian with Broken Scale and Chiral Symmetry IV: Nucleons and Mesons at Finite Temperature

G. W. Carter, P. J. Ellis

We study the finite temperature properties of an effective chiral Lagrangian which describes nuclear matter. Thermal fluctuations in both the nucleon and the meson fields are consi…

An Effective Lagrangian with Broken Scale and Chiral Symmetry III: Mesons at Finite Temperature

G. W. Carter, P. J. Ellis, S. Rudaz

We investigate the finite temperature behavior of the meson sector of an effective Lagrangian which describes nuclear matter. A method is developed for evaluating the logarithmic t…

An Effective Lagrangian with Broken Scale and Chiral Symmetry II: Pion Phenomenology

G. Carter, P. J. Ellis, S. Rudaz

We extend an effective Lagrangian embodying broken scale and chiral symmetry to include explicit chiral symmetry breaking and an additional chiral invariant term which allows for a…
