“…These experiments were performed in muonic 19 F by Culligan et al (1961) and Winston (1963). The first application of the hyperfine effect to the induced coupling g p was conducted by Deutsch et al (1968) Johnson et al (1996) at TRIUMF have extended the data to 23 Na.…”

Induced pseudoscalar coupling of the proton weak interaction

The induced pseudoscalar coupling gp is the least well known of the weak coupling constants of the proton's charged-current interaction. Its size is dictated by chiral symmetry arguments, and its measurement represents an important test of quantum chromodynamics at low energies. During the past decade a large body of new data relevant to the coupling gp has been accumulated. This data includes measurements of radiative and non radiative muon capture on targets ranging from hydrogen and few-nucleon systems to complex nuclei. Herein the authors review the theoretical underpinnings of gp, the experimental studies of gp, and the procedures and uncertainties in extracting the coupling from data. Current puzzles are highlighted and future opportunities are discussed.

“…The pile-up bit identifies events with a preceeding Ge detector hit within 50 µs and the overload bit identifies events with a preceeding > 10 MeV Ge detector hit within 500 µs (for details see Ref. [11]). Data were collected for 4.2 × 10 10 muon stops in the Na 35 Cl target, along with γ-ray background data from a LiCl target and x-ray calibration data from various materials.…”

“…However their interpretations are complicated by muon chemistry in 1 H and 2-body currents in 3 He, and the puzzling discrepancy between the values of g p from RMC on 1 H and OMC on 3 He is so far unexplained. In complex nuclei new results from allowed transitions on 11 B [10], 23 Na [11] and 28 Si [12][13][14] are also available. In nuclei the difficulty is disentangling the weak dynamics from nuclear structure.…”

We report measurements of γ-ray spectra from muon capture on 35 Cl. For the allowed Gamow-Teller transitions to the 35 S(2939, 3/2 + ) state and the 35 S(3421, 5/2 + ) state we obtained their capture rates, hyperfine dependences and γ-ν correlation coefficients. The capture rates and hyperfine dependences were compared to shell model calculations using the complete 1s-0d space and the universal SD interaction. With g p /g a = 6.7 and g a = −1.00 (or g a = −1.26) we found agreement of the model and the data at the 1-2 σ level. However, we caution that the transitions are sensitive to ℓ = 2 forbidden matrix elements.Typeset using REVT E X 1
