THE RADIATIVE CAPTURE OF $mu$$sup -$-MESON BY PROTON

Journal Article · · Sci. Sinica (Peking)
OSTI ID:4139771
The radiative capture of mu /sup -/-mesons by protons is treated by the renormalized universal Fermi interaction of the V-A type and Zel'dowich's theory on mu -meson hydrogen. Contrary to the result of Dee, Huang, and Yang, it is found that if the effect of the strong interaction is neglected, it is impossible for photons to be emitted during the capture. The influence of the strong interaction consists of the effect of the magnetic moment of the nucleon and the renormalization effect on the universal Fermi weak interaction. The effect of the anomalous magnetic moment is negligible. The contribution of protons to the emnission of photons is not small in comparison with that of the mu -meson, due to the renormalization effect on the universal Fermi weak interaction. The photons emitted are no longer 100% right hand polarized. It is estimated that only 82% of the photons have spins parallel to momentum. The
