229. Present status and future experiments in fundamental muon physics

Prof. David Hertzog (University of Washington)

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles

Oral

Current and planned experiments using muons as a probe, or as particle to be studied in and of itself, continue to shed light on fundamental physics many decades after its discovery. We continue to be fascinated by the atomic physics implications of the muonic Lamb shift measurements on the proton radius, the nuclear astrophysics implications related to determining the muon capture rate in...

210. The MuSun Experiment: First analysis of production data

Ms Rachel Ryan (University of Washington)

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles

Oral

Using a unique cryogenic time projection chamber as an active stopping target, the MuSun experiment has acquired the $10^{10}$ fully reconstructed muon decay events necessary to measure the rate of muon capture on the deuteron to better than 1.5\% precision. Once completed, the analysis will lead to a benchmark result in calibrating weak interactions in the two nucleon system, relevant for...

223. Measurement of muonic hydrogen 1S hyperfine splitting at RIKEN-RAL

Prof. Masahiko Iwasaki (RIKEN)

Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles

Oral

All the hierarchy down to hadron, matter can be divided into constituent particles, but hadron like proton, which have finite size and consist from infinite number of quarks and gluons, cannot be subdivided. Thus, how they are formed and the internal structures are the matter of interest for long time. Recently, the proton charge radius was measured by Lamb-shift of muonic hydrogen atom. This...

188. Low emittance muon source for muon g-2/EDM at J-PARC

Dr Glen Marshall (TRIUMF)

Low energy precision tests of the Standard Model

Oral

The anomalous magnetic moment of the muon, a_mu = (g_mu - 2)/2, has been measured to 0.54 ppm at BNL (E821), and when compared to the Standard Model (SM) calculation of similar precision, a discrepancy of about 3 sigma remains unexplained. A similar method will be used at FNAL (E989) with the goal of achieving a factor of four increase in experimental precision. An independent method...
