Here's a slightly modified version:

Muon Capture on the Proton

Abstract.  Muon capture on the proton is sensitive to the weak
pseudoscalar form factor, g_P, one of the basic parameters
characterizing the nucleon electroweak charged-current interaction.
There is a precise theoretical prediction for g_P based on chiral
symmetry of QCD, yet the results of past experiments are
controversial: they are dependent on a poorly-known, mu-molecular
kinetic parameter, and there is no point of mutual agreement
between theory and all experiments.  The goal of the MuCap
experiment is to clarify the situation by measuring the rate of
muon capture on the free proton to 1%, which determines g_P to 7%,
higher precision than achieved in previous experiments and without
ambiguities in the interpretation.  This talk will cover the
motivation for and design of the MuCap experiment, and first
physics results from the new measurement will be presented.
