Abstract

The time evolution of a system where a uniform and classical SU(3) color electric field and quantum fields of quarks interact with each other is studied focusing on non-perturbative pair creation and its back reaction. We characterize a color direction of an electric field in a gauge invariant way, and investigate its dependence. Momentum distributions of created quarks show plasma oscillation as well as quantum effects such as the Pauli blocking and interference. Pressure of the system is also calculated, and we show that pair creation moderates degree of anisotropy of pressure. Furthermore, enhancement of pair creation and induction of chiral charge under a color magnetic field which is parallel to an electric field are discussed.

Fast Vacuum Decay into Quark Pairs in Strong Color Electric and Magnetic Fields

Journal Article Hidaka, Y; Iritani, T; Suganuma, H - AIP Conference Proceedings

We study quark-pair creations in strong color electomagnetic fields. We point out that, for massless quarks, the vacuum persistency probability per unit space-time volume is zero, i.e., the quark-pair creation rate w is infinite, in general homogeneous color electromagnetic fields, while it is finite when the color magnetic field is absent. We find that the contribution from the lowest Landau level (LLL) dominates this phenomenon. With an effective theory of the LLL projection, we also discuss dynamics of the vacuum decay, taking into account the back reaction of pair creations.

Nonperturbative enhancement of heavy quark-pair production in a strong SU(2) color field

Journal Article Levai, Peter; Skokov, Vladimir - Physical Review. D, Particles Fields

Nonperturbative charm and bottom quark-pair production is investigated in the early stage of heavy-ion collisions. The time-dependent study is based on a kinetic description of fermion-pair production in strong non-Abelian fields. We introduce a time-dependent chromo-electric external field with a pulselike time evolution to simulate the overlap of two colliding heavy ions. The calculations is performed in a SU(2) color model with finite current quark masses. Yields of heavy quark pairs are compared to the ones of light and strange quark pairs. We show that the small inverse duration time of the field pulse determines the efficiency of the quark-pairmore »« less

Casimir dependence of transverse distribution of pairs produced from a strong constant chromo-electric background field

Journal Article Cooper, Fred; Mihaila, Bogdan; Dawson, John - Physical Review. D, Particles, Fields, Gravitation and Cosmology

Recently the transverse distribution of particle production from strong constant chromo-electric fields has been explicitly calculated in Ref. 1 for soft-gluon production and in Ref. 2 for quark (antiquark) production. This particle production method, originally discussed by Heisenberg and Euler, Schwinger and Weisskopf, has a long history as a model of the production of the quark gluon plasma following a relativistic heavy ion collision. The physical picture considered here is that of two relativistic heavy nuclei colliding and leaving behind a semi-classical gluon field which then non-perturbatively produces gluon and quark-antiquark pairs via the Schwinger mechanism.

Strong-coupling field theories. II. Fermions and gauge fields on a lattice

Journal Article Drell, S; Weinstein, M; Yankielowicz, S - Phys. Rev., D; (United States)

This paper (the second in a series) reports our recent progress in the study of strong-coupling quantum field theories on a lattice. In particular we study theories involving fermions and gauge fields and pay special attention to the peculiar problems encountered when one formulates theories of fermions on a lattice. It is unique to our approach that we preserve local chiral symmetry and at the same time correctly count the number of fermionic states. We demonstrate how our formalism works with the lattice Thirring and Schwinger models, whose continuum limits are solvable in one space and one time dimension. Wemore »« less

Fermion pair production in a strong electric field

Journal Article Kluger, Y; Eisenberg, J; Svetitsky, B; ... - Physical Review, D (Particles Fields); (United States)

The initial-value problem for the quantum back reaction in spinor QED is formulated and solved in the semiclassical mean-field approximation for a homogeneous but time-dependent electric field {ital E}({ital t}). We apply the method of adiabatic regularization to the Dirac equation in order to renormalize the expectation value of the currect and derive a finite coupled set of ordinary differential equations for the time evolution of the system. We solve this system in 1+1 dimensions numerically and compare the solution to a simple model based on a relativistic Boltzmann-Vlasov equation, with a particle production source term inferred from the Schwingermore »« less
