R3.00002: Dissertation Award in Nuclear PhysicsTalk: An Introduction to the MuCap Experiment Invited Speaker: MuCap is a collaborative effort to make a high precision measurement of the rate of nuclear muon capture in hydrogen gas. Muon capture is of contemporary interest because its large momentum transfer makes it uniquely sensitive to the nucleon's pseudoscalar coupling ${\textsl g}^{}_P$, which is currently the least well known of the nucleon's electroweak form factors. In 2007 MuCap published its first results, reporting the most precise determination of ${\textsl g}^{}_P$ to date. In this talk I will give a general introduction to the MuCap experiment by discussing the rich physics surrounding muon capture, surveying previous experiments in the field, and describing the techniques that distinguish MuCap from its predecessors.

R3.00003: Dissertation Award in Nuclear Physics Talk: Data Analysis and Present Status of the MuCap Experiment Invited Speaker: The MuCap experiment measures the rate of muon capture on the proton from a known initial state, providing an unambiguous determination of the pseudoscalar coupling $g_{\rm P}$ of the proton's weak interaction. In 2007 the MuCap collaboration released their first physics results for $g_{\rm P}$ with 20\% precision, a statistics limited, unambiguous measurement of this coupling constant surpassing all previous efforts. Since that first data collection, several improvements to the experiment were made towards the final precision goal of $g_{\rm P}$ to 7\%. In this talk, the MuCap first physics measurement will be discussed, and the status of the subsequent experimental and analysis effort will be described. [Preview Abstract] |
