“…22 However, there are two other well-known methods, those of Chew and Mandelstam 20 and of Froissart, 17 which may be used to handle inelasticity. The Frye-Warnock method is best suited for the right-hand cutoff procedure, while the Froissart method is more easily applied in the left-hand cutoff case.…”

It is found that the optimal determinantal approximation, as proposed in an earlier paper, leads to accurate solutions for the ND~l equations of irN scattering in the P n state. Both left-hand and right-hand cutoff procedures are used in the formulation of the problem, with similar results. Inelasticity is treated by a method proposed by Froissart. It is shown that a qualitatively correct irN P n phase shift in the low-energy region may be reproduced in a one-channel calculation without Castillejo-Dalitz-Dyson poles, provided that the inelasticity factor is chosen properly. A two-channel model with the (wN*) as the second channel is discussed, and it is shown that the inelasticity obtained in a rough approximation to the coupled unitarity relations is adequate in generating the "zero" of the Pu phase shift. Some implications concerning the nonequivalence of one-channel and multichannel ND~X formalisms are discussed.

“…(5.1a) and consider the problem as a one-channel inelastic N/D system. Noting that one-channel inelastic unitarity may be stated in the following form 22 : The Froissart method of Sec. 4 is then applicable to such a system, whereby a phase shift is obtained.…”

Intermediate Boson. III. Virtual-Boson Effects in Neutrino Trident Production

The production of lepton tridents by neutrinos in a Coulomb field i s a sensitive test of the diagonal t e r m s in weak-interaction theory. If a charged vector boson exists then it can participate in such reactions as a virtual particle o r a real one if the incident beam energy i s sufficiently high. A neutral vector boson with no magnetic moment cannot interact with the electromagnetic field; s o it participates only a s a virtual particle. We examine in this paper two different effects due to these bosons. F i r s t that they have different effective couplings which modify the V-A interaction to a more general combination of vector and axial-vector currents. At this level changes in the over-all coupling strength a r e more important than retaining effects due to the virtual-boson propagators. The recent model of Weinberg belongs to this classification. Second, we investigate the propagator effect of a charged vector boson mediating the usual V -A theory.
