Atomic parity violation in cesium and implications for new physics
Recent high-precision measurements of atomic parity-nonconserving transitions between the 6S and 7S states of cesium allow for a determination of the weak nuclear charge with a precision of 1.3%, providing an improved test of the standard model at low energy. Implications for new physics are examined in terms of low energy effects on the weak charge, in particular contact interactions and scala...
متن کاملAtomic Parity Violation and Precision Electroweak Physics -an Updated Analysis
A new analysis of parity violation in atomic cesium has led to the improved value of the weak charge, QW (Cs) = −72.06± 0.46. The implications of this result for constraining the Peskin-Takeuchi parameters S and T and for guiding searches for new Z bosons are discussed. PACS Categories: 11.30.Er, 12.15.Ji, 12.15.Mm, 12.60.Cn One prediction of the unified theory of weak and electromagnetic inter...

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, δNQW , requiring new physics of a type not severely constrained by the high energy precision data.
