Probing color-singlet exchange in -jet events at the LHC
The purely electroweak process (via -channel or
exchange) provides a copious and fairly clean source of color-singlet exchange
events in collisions at the LHC. A judicious choice of phase-space region
allows the suppression of QCD backgrounds to the level of the signal. The
color-singlet-exchange signal can be distinguished from QCD backgrounds by the
radiation patterns of additional minijets in individual events. A rapidity-gap
trigger at the minijet level substantially enhances the signal versus the
background. Analogous features of weak boson scattering events make -jet
events at the LHC an ideal laboratory for investigation of the soft-jet
activity expected in weak-boson scattering events.Comment: 24 pages (with 7 embedded figures), Revtex, uses epsf.sty.
