On Radiative Muon Capture in Hydrogen.
Original language description
We analyze the radiative capture of the negative muon in hydrogen using amplitudes derived within the chiral Lagrangian approach. Besides the leading order terms, we extract from these amplitudes the corrections up the order O(1/M.sup.2./sup.) (M is thenucleon mass). We estimate also the .DELTA.(1232) excitation effects and processes discribed by an anomalous Lagrangian. Employing the off-shell parameters of the model obtained from the analysis of the pion photoproduction allows us to explain two timesmore of the discrpancy between the PCAC value g.sup.PCAC.sub.P./sub. of the induced pseudoscalar constant g.sub.p. and of g.sub.p extracted from the recent TRIUMF experiment, than the standard approach can explain. By varying these parameters indeppendently, the model can describe the high energy part of the experimental photon spectrum reasonably well for the values of g.sub.P .appreq. g.sup.PCAC.sub.P. Our results for ca=pture rates agree with the latest calculations within 10%.
