Contribution

It provides the latest single-coupling bounds on R-parity violating supersymmetry by incorporating recent experimental results and improved theoretical calculations.

Findings

Stronger bounds on certain R-parity violating couplings.

Updated constraints based on new cesium weak charge measurements.

Refined predictions for semileptonic D-decays.

Abstract

We update the single-coupling bounds on R-parity violating supersymmetry using the most up to date data as of October 2009. In addition to the data listed in the 2009 Review of Particle Properties, we utilize a new determination of the weak charge of cesium-133, and preliminary tau-decay branching fractions from Babar. Analysis of semileptonic D-decay is improved by the inclusion of experimentally measured form-factors into the calculation of the Standard Model predictions.
