Comment on ``Validity of certain soft-photon amplitudes''
M. K. Liou, R. Timmermans, B. F. Gibson +1
The criteria suggested by Welsh and Fearing (nucl-th/9606040) to judge the validity of certain soft-photon amplitudes are examined. We comment on aspects of their analysis which le…
The Pauli principle in the soft-photon approach to proton-proton bremstrahlung
M. K. Liou, R. Timmermans, B. F. Gibson
A relativistic and manifestly gauge-invariant soft-photon amplitude, which is consistent with the soft-photon theorem and satisfies the Pauli Principle, is derived for the proton-p…
Novel soft-photon analysis of below pion-production threshold
M. K. Liou, R. Timmermans, B. F. Gibson
A novel soft-photon amplitude is proposed to replace the conventional Low soft-photon amplitude for nucleon-nucleon bremsstrahlung. Its derivation is guided by the standard meson-e…
Anatomy of the Soft-Photon Approximation in Hadron-Hadron Bremsstrahlung
M. K. Liou, Dahang Lin, B. F. Gibson
A modified Low procedure for constructing soft-photon amplitudes has been used to derive two general soft-photon amplitudes, a two-s-two-t special amplitude and a two…
