Title:Inclusive pion production at large and small transverse momentum in a model of hadrons
Author(s):Roth, Michael W.

Subject(s):pion production
Abstract:Inclusive pion production at large and small transverse momentum PT has been studied in a model of hadrons. The model has the Feynman diagram structure of the multiperipheral model. The off-shell hadron amplitudes are taken from field theoretic ideas, the relationship with electroproduction, factorization of off-shell behavior, a double offshell enhancing effect, and experimental input. The model is calculated using numerical techniques. The main results are: 1) the model gives a good quantitative description of the whole Peyrou plot; 2) large PT scattering is controlled by far off-shell amplitudes and the power law of PT -8 seen at ISR is in part due to the faster off-shell falloff of exclusive channels relative to inclusive ones; 3) the steeper falloff at Fermilab energies is accounted for in a natural way; and 4) there is a threshold in XL = 2PT/[S] beyond which the spectrum is dominated by fragments of the incident particles.
