Title: Very Small Asymmetries and the Weak Interaction  

Abstract: The nature of the weak interaction at low energy scales is not completely known. The weak interaction can be studied by observing parity violation, and asymmetries between cross-sections provide the best experimental technique to do so. Due to the small size of the weak coupling constant, these asymmetries can be very small, and their experimental study is a challenge. Two such experiments in development, which will make parity-violating asymmetry measurements with parts per billion precision, are: NPDGamma (n+p->d+gamma) at Los Alamos National Laboratory, and Qweak at the Thomas Jefferson National Accelerator Facility. The two experoments have many interesting similarities and differences in both physics and technique, and are illustrative of the immediate future of the field of precision measurements in fundamental symmetries.
