Censored EM algorithm for Weibull mixtures: application to arrival times of market orders
Markus Kreer, Ayse Kizilersu, Anthony W. Thomas
In a previous analysis the problem of "zero-inflated" time data (caused by high frequency trading in the electronic order book) was handled by left-truncating the inter-arrival tim…
Triple-gluon and quark-gluon vertex from lattice QCD in Landau gauge
Andre Sternbeck, Paul-Hermann Balduf, Ayse Kızılersu +4
We report on preliminary results for the triple-gluon and the quark-gluon vertex in Landau gauge. Our results are based on two-flavor and quenched lattice QCD calculations for diff…
Quark-gluon vertex in general kinematics
Ayse Kizilersu, Derek B. Leinweber, Jon-Ivar Skullerud +1
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 Dirac-vector part of the vertex is co…
On conditions for the nonperturbative equivalence of ultraviolet cut-off and dimensional regularization schemes
Ayse Kizilersu, Tom Sizer, Anthony G. Williams
We consider procedures through which an ultraviolet cut-off regularization scheme can be modified to reproduce the same results for nonperturbative renormalized Green's functions a…
Analytic Form of the One-loop Vertex and of the Two-loop Fermion Propagator in 3-Dimensional Massless QED
A. Bashir, A. Kizilersu, M. R. Pennington
We evaluate the analytic expression for the one-loop fermion-boson vertex in massless QED3 in an arbitrary covariant gauge. The result is written in terms of elementary functions o…
