Nucleon Polarizabilities

The subject of nucleon polarizabilities in real, virtual, and doubly virtual Compton scattering is discussed with respect to what is known and how such quantities can be extracted from data.Comment: 13 page Latex file; Talk given at Chiral Dynamics 2000 Workshop, Jefferson Lab, July 200

How Large is the "Natural" Magnetic Moment?

The "natural" magntic moment of a particle of spin S is generally assumed to be that given by the Belinfante conjecture and has the value g=1/S for its gyromagnetic ratio. Thus, for the spin 1/2 electron we find the Dirac value $g_e=2$. However, in the standard model the charged W boson, a spin one particle, is found to have the value $g_{W^+}=2$. We show how this result comes about and argue that the "natural" value for any particle of spin S should be g=2, independent of spin.Comment: 23 pages, 2 figures, to be published in the American Journal of Physic

Low Energy Compton Scattering and Nucleon Structure

The low energy virtual Compton scattering process $eN\to e'N\gamma$ offers a new and potentially high resolution window on nucleon sturcture via measurement of so-called generalized polarizabilities (GPs). We present calculations of GPs within heavy baryon chiral perturbation theory and discuss present experimental efforts.Comment: Talk given at Workshop on "Physics of Mesons, Baryons and Nuclei," Cracow, May 1998, in celebration of 60th birthday of Prof. Josef Spet

Neutrinos and the Standard Model

Since their "discovery" by Pauli in 1930, neutrinos have plaed a key part in confirmation of the structure of the standard model of strong and electroweak interactions. After reviewing ways in which this has been manifested in the past, we discuss areas in which neutrinos continue to play this role.Comment: 16 page latex file, Talk presented at Carolina Neutrino Workshop, Columbia, SC, March 200

Introduction to Effective Field Theory

An introduction to methods of effective field theory is given. Examples are presented, including Rayleigh scattering from nonrelativistic quantum mechnics, chiral perturbation theory/QCD as well as electromagnetic and weak interactions of nucleons.Comment: 12 page latex file, Talk given at European Few Body Physics Meeting, Evora, Portugal, September 200

Hadronic Parity Violation: an Analytic Approach

Using a recent reformulation of the analysis of nuclear parity-violation (PV) within the framework of effective field theory (EFT), we show how predictions for parity-violating observables in low-energy light hadronic systems can be understood in an analytic fashion. It is hoped that such an analytic approach may encourage additional experimental work as well as add to the understanding of such parity-violation phenomena, which is all too often obscured by its description in terms of numerical results obtained from complex two-body potential codes.Comment: 49 pages, 4 figures, dedicated to the memory of Dubravko Tadi

Low Energy Tests of Chiral Symmetry

The present status of low energy test of chiral invariance via chiral perturbation theory is reviewed, both in the meson and baryon sectors, and future prospects are discussed.Comment: Invited talk given at PANIC 96, Standard 8 page Latex fil
