We consider the scattering of lightlike matter in the presence of a heavy scalar object (such as the Sun or a Schwarzschild black hole). By treating general relativity as an effective field theory weâ€¦ (More)

We examine the corrections to the lowest order gravitational interactions of massive particles arising from gravitational radiative corrections. We show how the masslessness of the graviton and theâ€¦ (More)

In their 1947 study of cosmic rays Rochester and Butler obtained evidence for the existence of massive unstable particles. While examining muon and electron showers using a cloud chamber they securedâ€¦ (More)

We demonstrate how heavy mass methods, previously applied to chiral perturbation theory calculations involving the interactions of nucleons and pions, can be generalized to include interactions withâ€¦ (More)

We consider scattering in quantum gravity and derive long-range classical and quantum contributions to the scattering of light-like bosons and fermions (spin-0, spin1 2 , spin-1) from an externalâ€¦ (More)

We analyze polarized Compton scattering which provides information on the spin-structure of the nucleon. For scattering processes with photon energies up to 100 MeV the spin-structure dependence canâ€¦ (More)

We investigate the use of long distance regularization in SU(3) baryon chiral perturbation theory with decuplet fields. The one-loop decuplet contributions to the octet baryon masses, axialâ€¦ (More)

Compton scattering results are used to probe proton structure via measurement of higher order polarizabilities. Values for Î±pE2, Î² p E2, Î± p EÎ½ , Î² EÎ½ determined via dispersion relations are comparedâ€¦ (More)

The Electromagnetic and Hadronic physics sub-community of nuclear physics held a town hall meeting at Jefferson Lab during November 30 to December 4 of 2000. This is is our combined contribution toâ€¦ (More)

Recently methods have been developed which exploit the chiral symmetry of QCD in order to make rigorous contact with low energy particle physics phenomenology. In these lectures we present aâ€¦ (More)
