Interplay of dynamical and explicit chiral symmetry breaking effects on a quark
(Amer Physical Soc, 2019-05-20)
The relative contributions of explicit and dynamical chiral symmetry breaking in QCD models of the quark-gap equation are studied in dependence of frequently employed Ansatze for the dressed interaction and quark-gluon ...
Interplay of dynamical and explicit chiral symmetry breaking effects on a quark

Supergraph approach in a higher-order linear delta expansion calculation of the effective potential for F-type broken supersymmetry
(2012-10-11)
In this work, we adopt the simplest model that spontaneously breaks supersymmetry, namely, the minimal O'Raifeartaigh model. The effective potential is computed in the framework of the linear delta expansion approach up ...
Magnetic seed and cosmology as quantum hall effect
(Elsevier Science, 2018-10)
In the framework of a bimetric model, we discuss a relation between the (modified) Friedmann equations and a mechanical system similar to the quantum Hall effect problem. Firstly, we show how these modified Friedmann ...
Effects of dynamical masses of gluons and quarks on hadronic B decays
(2010-12-01)
We study hadronic annihilation decays of B mesons within the perturbative QCD at collinear approximation. The regulation of endpoint divergences is performed with the help of an infrared finite gluon propagator characterized ...

Soft thermal contributions to 3-loop gauge coupling
(2018)
We analyze 3-loop contributions to the gauge coupling felt by ultrasoft ("magnetostatic") modes in hot Yang-Mills theory. So-called soft/hard terms, originating from dimension-six operators within the soft effective theory, ...
Quantum confined scattering beyond the s-wave approximation
(Progress Theoretical Physics Publication Office, 2007-01-01)
A dual confinement induced resonance effect first observed numerically in a paper P. I. Kim, V. S. Melezhik and P. Schmelcher, Phys. Rev. Lett. 97 (2006), 193203] predicts the possibility of suppressing the effective ...
