Multichannel processes inV- andVΘ i -sectors in an extended Lee model

Abstract

The LEHMANN--SYMANZIK--ZIMMEIIM&NN (LSZ) formalism is used in a multi-O extended LEE model to calculate the relevant multichannel scattering and production amplitudes. The extended rr/ulti-O LEE model introduces nO particles in addition to heavy recoi]less V and N particles of the normal LEE mode]. The processes allowed ate V ~~_ NOi, for i = = 1,2 ..... n. In the V-and VOi-sectors, a]l the T-functions are obtained by solving the MATTHEWS--SALAM equations for the T-functions. The multichanne] seattering and production amplitudes ate also evaluated.
