The pointlike coupling of the photon to the quark current yields simple predictions for the leading fast mesons in high-p/sub t/ ..gamma..N (lN), e/sup +/e/sup -/, and ..gamma gamma.. reactions, e.g., for ..gamma..p ..-->.. hX one gets K/sup +/:K/sup -/:K/sup 0/:K-bar/sup 0/=8:0:1:0 and ..pi../sup +/:..pi../sup -/:..pi../sup 0/=8:1:9/2. It is noted that in ..gamma..N collisions the dominant jet cross section arises from the hard subprocess: ..gamma..+gluon ..-->.. q+q-bar. This may yield the gluon distribution via s s/sub 0/(dsigma/ds/sub 0/) K/sup -1/=f/sub g/(x) and lead to a sum rule: ..integral..s/sub 0/ /sup 2/(dsigma/ds/sub 0/) ds/sub 0//sK=phixf/sub g/(x) dx, where K=4..pi cap alpha cap alpha../sub s/ln(s/2p/sub t/min /sup 2/).
