J. Govaerts, SYMMETRY-TESTS OF THE ELECTROWEAK INTERACTION FROM MUON-CAPTURE ON HE-3-STAR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 402(2-3), 1998, pp. 303-310
Precision measurements in muon capture on He-3 to the triton channel p
rovide for interesting tests of the charged electroweak interaction, w
hether within the Standard Model or beyond it. Based on the statistica
l capture rate and the triton asymmetry, both the object of recent and
on-going experiments using polarised He-3 targets, examples of such r
ests are presented, and shown to lead to stringent complementary const
raints for which further dedicated experimental as well as theoretical
efforts are required.
