Current Issues in the Nuclear Chiral Perturbation Approach

Abstract

After outlining the basic ideas of nuclear chiral perturbation theory, I discuss its application, presenting three examples which I believe are of great current interest: (1) Exchange currents in those cases where the leading chiral-order terms dominate; (2) The near-threshold $p+p\ra p+p+π^0$ reaction, for which the leading order terms are suppressed and consequently higher-order corrections play a prominent role; (3) Radiative $μ$-capture on the proton.
