Gauge-Invariant Quantities Characterizing Gauge Fields in Chromodynamics
Gouranga C. Nayak, Robert Shrock
We calculate Lorentz-invariant and gauge-invariant quantities characterizing the product , where denotes the matrix for the generator in…
Path Integration in QCD with Arbitrary Space-Dependent Static Color Potential
Gouranga C. Nayak
We perform path integral for a quark (antiquark) in the presence of an arbitrary space-dependent static color potential A^a_0(x)(=-\int dx E^a(x)) with arbitrary color index a=1,2,…
Schwinger Mechanism for Fermion Pair Production in the Presence of Arbitrary Time Dependent Background Electric Field
Fred Cooper, Gouranga C. Nayak
We study the Schwinger mechanism for the pair production of fermions in the presence of an arbitrary time-dependent background electric field E(t) by directly evaluating the path i…
Schwinger Mechanism in the Presence of Arbitrary Time Dependent Background Electric Field
Fred Cooper, Gouranga C. Nayak
We study, for the first time, the Schwinger mechanism for the pair production of charged scalars in the presence of an arbitrary time-dependent background electric field E(t) by by…
Shift Theorem Involving the Exponential of a Sum of Non-Commuting Operators in Path Integrals
Fred Cooper, Gouranga C. Nayak
We consider expressions of the form of an exponential of the sum of two non-commuting operators of a single variable inside a path integration. We show that it is possible to shift…
Gluon Pair Production From Space-Time Dependent Chromofield
Gouranga C. Nayak, Walter Greiner
We compute the probabilty for the processes A -> q \bar{q}, gg via vacuum polarization in the presence of a classical space-time dependent non-abelian field A by applying the backg…
