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...

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...

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...

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...
