Regarding proton form factors
J. C. R. Bloch, A. Krassnigg, C. D. Roberts
The proton's elastic electromagnetic form factors are calculated using an Ansatz for the nucleon's Poincare' covariant Faddeev amplitude that only retains scalar diquark correlatio…
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…
