Query: Diffractive jet production in a simple model with applications to HERA   In diffractive jet production, two high energy hadrons A and B collide and
produce high transverse momentum jets, while hadron A is diffractively
scattered. Ingelman and Schlein predicted this phenomenon. In their model, part
of the longitudinal momentum transferred from hadron A is delivered to the jet
system, part is lost. Lossless diffractive jet production, in which all of this
longitudinal momentum is delivered to the jet system, has been discussed by
Collins, Frankfurt, and Strikman. We study the structure of lossless
diffractive jet production in a simple model. The model suggests that the
phenomenon can be probed experimentally at HERA, with A being a proton and B
being a bremsstrahlung photon with virtuality $Q^2$. Lossless events should be
present for small $Q^2$, but not for $Q^2$ larger than $1/R_{\rm P}^2$, where
$R_{\rm P}$ is a characteristic size of the pomeron.
