Quark-gluon vertex from Nf=2 lattice QCD
Ayşe Kızılersü, Orlando Oliveira, Paulo J. Silva +2
We study the quark-gluon vertex in the limit of vanishing gluon momentum using lattice QCD with 2 flavors of O(a) improved Wilson fermions, for several lattice spacings and quark m…
Dynamical mass generation in unquenched QED using the Dyson--Schwinger equations
Ayse Kizilersu, Michael R. Pennington, Tom Sizer +2
We present a comprehensive numerical study of dynamical mass generation for unquenched QED in four dimensions, in the absence of four-fermion interactions, using the Dyson--Schwing…
Fractional Poisson processes and their representation by infinite systems of ordinary differential equations
Markus Kreer, Ayse Kizilersu, Anthony W. Thomas
Fractional Poisson processes, a rapidly growing area of non-Markovian stochastic processes, are useful in statistics to describe data from counting processes when waiting times are…
Strongly-Coupled Unquenched QED4 Propagators Using Schwinger-Dyson Equations
Ayse Kizilersu, Tom Sizer, Anthony G. Williams
We study unquenched QED in four dimensions using renormalised Schwinger-Dyson equations and focus on the behaviour of the fermion and photon propagators. For this purpose we use an…
Quark-gluon vertex in arbitrary kinematics
Jon-Ivar Skullerud, Patrick O. Bowman, Ayse Kizilersu +2
We compute the quark-gluon vertex in quenched lattice QCD, in the Landau gauge using an off-shell mean-field O(a)-improved fermion action. The complete vertex is computed in two sp…
Does the weak coupling limit of the Burden-Tjiang deconstruction of the massless quenched QED3 vertex agree with perturbation theory?
A. Bashir, A. Kizilersu, M. R. Pennington
We derive constraints on the non-perturbative 3-point fermion-boson transverse vertex in massless QED3 from its perturbative calculation to order . We also check the transversal…
The non-perturbative three-point vertex in massless quenched QED and perturbation theory constraints
A. Bashir, A. Kizilersu, M. R. Pennington
Dong, Munczek and Roberts have shown how the full 3-point vertex that appears in the Schwinger-Dyson equation for the fermion propagator can be expressed in terms of a constrained…
ONE LOOP QED VERTEX IN ANY COVARIANT GAUGE: ITS COMPLETE ANALYTIC FORM
A. Kizilersu, M. Reenders, M. R. Pennington
The one loop vertex in QED is calculated in arbitrary covariant gauges as an analytic function of its momenta. The vertex is decomposed into a longitudinal part, that is fully resp…
