Propagator Groups

This paper introduces propagator groups as an abstraction for controlling the execution of propagators as implementations of constraints. Propagator groups enable users of a constraint programming system to program how propagators within a group are executed. The paper exemplifies propagator groups for controlling both propagation order and propagator interaction. Controlling propagation order ...

The normalized mode propagator

For the Randall-Sundrum brane world where a positive tension Minkowski brane is embedded in AdS 5 , two candidate propagators have been suggested in the literature, one being based on the normalized mode solutions to the source-free volcano potential fluctuation equation, and the other being the Giddings, Katz and Randall outgoing Hankel function based one. We show that while both of these two ...

Modelling the gluon propagator

where the subscript f denotes the finer lattice (β = 6.2 in this study) and the subscript c denotes the coarser lattice (β = 6.0). We can use this relation to study directly the scaling properties of the lattice gluon propagator by matching Talk presented by D. B. Leinweber UKQCD Collaboration the data for the two values of β. This matching can be performed by adjusting the values for the ratio...

Modelling the quark propagator

The quark propagator is at the core of lattice hadron spectrum calculations as well as studies in other nonperturbative schemes. We investigate the quark propagator with an improved staggered action (Asqtad) and an improved gluon action, which provides good quality data down to small quark masses. This is used to construct ansätze suitable for model hadron calculations as well as adding to our ...
