The SG Propagator
b = l/16m, Mn =
(2n+1)m and DF=[K2-Mn+ie)-1 is the usual Feynman Propagator in momentum space. The SG
poropagator like
other solitary wave propagators is essentially a superposition of Feynman propagators it has,
however, the advantage
of automatically exchanging a series of massive bosons with a
minimum of parameters . The sequence of
bosons lead to
superposition of attractive as well as repulsive Yukawa and exponential potential terms in
configuration (position)
space2.
