Gluon distribution in hadrons

We consider the effects of hadron size and quark composition on the distribution of gluons in mesons and baryons. Coherence effects in the color-singlet bound state eliminate the usual quark-mass infrared singularity. The color cancellations are important for all x/sub gluon/ unless the gluon transverse momentum is large compared to the inverse hadron size. Using a simple model for the meson bound state, we relate the scale size of color coherence to the scale of the electromagnetic form factor. Applications to the flavor and quark-number dependence of total cross sections and gluon-induced reactions are discussed.
