Strongly-interacting color-singlet exchange in $\bar{p}$-p collisions at √s = 1800 GeV

Results are presented from an analysis of the particle multiplicity between high transverse energy jets in {anti p}-p collisions at {radical}s = 1,800 GeV. The data were collected using the D0 Detector at Fermi National Accelerator Laboratory. The authors observe an excess of events at low multiplicity which is consistent with strongly interacting color-singlet exchange. The fraction of events due to color-singlet exchange is measured as a function of the transverse energy and rapidity separation of the jets and is compared to several theoretical models for color-singlet exchange.
