Title: Hadron constituents and e + e - colliding-beam experiments

Abstract

In order to test the idea that hadrons are made out of some fundamental constituents, it is most important to state precisely, in a general way, what we mean by the hadronic constituents. We call the constituents partons and state a set of basic assumptions. They are weaker than any of the assumptions previously used in connection with the model. With these assumptions, we show that if R≡ σ(e +e - → hadrons)/σ(e +e - → /μ +μ -) increases faster than or equal to log Q/M at large Q, ‘then the multiplicity of hadrons in e +e - → hadrons must increase at least as fast as $$\frac{Q}{M}$$ /log$$\frac{Q}{M}$$. Q is the center of mass energy of the colliding beam, The increase in R with Q, itself, does not violate the basic concept of the parton model. If above relations between the increase in the cross section and the multiplicity is contradicted by experiments at large Q, however, the parton model requires a major overhaul.
