Search for 1/p^2 Corrections to the Running QCD Coupling
G. Burgio, F. Di Renzo, C. Parrinello +1
We investigate the occurrence of power terms in the running QCD coupling by analysing non-perturbative measurements of alpha_s (p) at low momenta obtained from the lattice three-gl…
Soft Pomeron Physics on the Lattice
D. S. Henty, C. Parrinello, D. G. Richards +1
We discuss strategies for using lattice QCD to investigate some topics in strong interaction phenomenology which are usually related to soft pomeron exchange. These include hadroni…
Lattice Study of the Pomeron
D. S. Henty, C. Parrinello, D. G. Richards +1
We investigate the phenomenology of the Landshoff-Nachtmann two-gluon-exchange model of the Pomeron using gluon propagators computed in the Landau gauge within quenched lattice QCD…
The Strong Coupling Constant from the Lattice 3-Gluon Vertex
D. Henty, C. Parrinello, C. Pittori
We compute the QCD running coupling on the lattice as defined from the 3-gluon vertex. We present the results of an exploratory study at on a lattice, which show tha…
The SU(3) running coupling from lattice gluons
D. S. Henty, C. Parrinello
We provide numerical results for the running coupling in Yang-Mills theory as determined from an analysis of lattice two and three-point gluon correlation functions. The co…
