*Hadronic contribution to the muon g-2*

Dru Renner
Jefferson Lab

The hadronic contributions to the anomalous magnetic moment of the
muon are an interesting challenge for lattice QCD, especially given a
persistent discrepancy between theory and experiment.  We have
calculated the leading-order hadronic contribution using lattice QCD.
Our focus has been on establishing what is required for a 
well-controlled first-principles calculation.  This is the first 
calculation with dynamical fermions to examine lattice artifacts, 
finite-size effects and disconnected diagrams, essentially all the major 
sources of error.  We have also studied the quark mass dependence with 
calculations at pion masses ranging from 650 MeV down to 270 MeV.  I 
will discuss a bit of the relevant phenomenology and then present our 
results.

*A Regge Model for Nucleon-Nucleon Scattering Amplitudes*

William Ford
ODU

We present a model to calculate nucleon-nucleon (NN) scattering
amplitudes, for Mandelstam s greater than 6 GeV2. The model,
based on Regge theory, is fully relativistic, and exhibits full
spin dependence. We relate the Regge exchanges to the Fermi
invariants, which gives an organized, and simplified method to
incorporate Regge exchanges into the NN amplitudes. Preliminary
results are presented.
