Abstract

A recent experimental determination of the weak charge of atomic cesium is used to get implications for possible new physics. The new data imply positive upper and lower bounds on the new physics contribution to the weak charge, delta_N Q_W, requiring new physics of a type not severely constrained by the high energy precision data.
