Selected nucleon form factors and a composite scalar diquark
J. C. R. Bloch, C. D. Roberts, S. M. Schmidt
A covariant, composite scalar diquark, Fadde'ev amplitude model for the nucleon is used to calculate pseudoscalar, isoscalar- and isovector-vector, axial-vector and scalar nucleon…
Memory effects and thermodynamics in strong field plasmas
J. C. R. Bloch, C. D. Roberts, S. M. Schmidt
We study the evolution of a strong field plasma using a quantum Vlasov equation with a non-Markovian source term and a simple collision term, and calculate the time dependence of t…
K -> pi pi and a light scalar meson
J. C. R. Bloch, M. A. Ivanov, T. Mizutani +2
We explore the Delta-I= 1/2 rule and epsilon'/epsilon in K -> pi pi transitions using a Dyson-Schwinger equation model. Exploiting the feature that QCD penguin operators direct K^0…
Nucleon form factors and a nonpointlike diquark
J. C. R. Bloch, C. D. Roberts, S. M. Schmidt +2
Nucleon form factors are calculated on q^2 in [0,3] GeV^2 using an Ansatz for the nucleon's Fadde'ev amplitude motivated by quark-diquark solutions of the relativistic Fadde'ev equ…
Pair creation: back-reactions and damping
J. C. R. Bloch, V. A. Mizerny, A. V. Prozorkevich +4
We solve the quantum Vlasov equation for fermions and bosons, incorporating spontaneous pair creation in the presence of back-reactions and collisions. Pair creation is initiated b…
Describing a1 and b1 decays
J. C. R. Bloch, Yu. L. Kalinovsky, C. D. Roberts +1
Two-body pion-radiating and weak decays of light axial-vector mesons and the rho are studied as a phenomenological application of the QCD Dyson-Schwinger equations. Models based on…
