Reciprocal space-time and momentum-space singularities in the narrow resonance approximation
A general scheme is proposed which makes explicit the relationship between the singularities of off-shell amplitudes in position-space and momentum-space in the narrow resonance approximation. In some ways this may be viewed as a duality scheme for amplitudes involving external quarks, in which narr...

| description | A general scheme is proposed which makes explicit the relationship between the singularities of off-shell amplitudes in position-space and momentum-space in the narrow resonance approximation. In some ways this may be viewed as a duality scheme for amplitudes involving external quarks, in which narrow resonances in certain channels build the Fourier transform of power singularities in x/sup 2/(x/sup mu / being a position vector). This scheme is made precise by dual string off-shell amplitudes. (11 refs). |
