Advanced muon and ultracold neutron sources
Oral
Japan Proton Accelerator Research Complex (J-PARC) is the high intensity
proton driver for particle, nuclear physics as well as material and life science,
built in Tokai, Japan . The facility has been in operation since 2008 and in the
process of achieving its design power of about 1 MW. We are exploring the
flavor physics with neutrino, kaon, and muon beams, as well as the...

The MuCap experiment at PSI has published its final result on $g_P$, the weak-pseudoscalar coupling of the proton.
A novel ultra-pure hydrogen TPC served as an imaging stopping volume. In gas, the $\mu p$ capture rate is relatively
immune to the poorly known molecular physics complications that plagued previous efforts by others.
The result, $g_P = 8.06 \pm 0.55 $ is in excellent...

In this talk we review the theoretical calculations of muon capture reactions in light nuclei performed within the chiral effective field theory (EFT). In this approach the pions and nucleons are retained as degrees of freedom, but their mutual interactions, and their interactions with an external electroweak current, are constrained by the the symmetries of QCD, in particular its...

Basic few-body nuclear systems are increasingly understood in terms of QCD-based effective field theories (EFT). These calculations precisely predict electro-weak observables and establish rigorous relations between muon capture and fundamental astrophysical processes like p-p fusion and neutrino break-up of the deuteron. Experimentally, the muon capture rate on the deuteron tests this modern...
