Abstract:

It is shown that a composite model of quark we have proposed can explain the P-8T behavior in large PT hadron production. The key point is that the form factor of quark behaves (Q2)-1/2 at large Q2 in our model. Our model makes unique predictions in many respects which are different from quark parton model with anomalous quark-quark scattering. In our model, ρppJ ∼PT-8(1-xT)5, ρπpJ ∼PT-8(1-xT)3·5, ρpp→π0X ∼(1-xT)3/2 near xT = 1 and dσ/dtpp →pp ∼s-10f(θ) at large s and fixed θ. The ratio of multiplicity functions in lepton processes to pp →Jet+X behaves (1-z) near z = 1. The exponent m(ρ∼PT-8(1-xT)m or (dσ/dz)/σ∼(1-z)m) in various single hadron production processes is also discussed.
