Hard colour singlet exchange at the Tevatron
Abstract
We have performed a detailed phenomenological investigation of the hard colour singlet exchange process which is observed at the Tevatron in events which have a large rapidity gap between outgoing jets. We include the effects of multiple interactions to obtain a prediction for the gap survival factor. Comparing the data on the fraction of gap events with the prediction from BFKL pomeron exchange we find agreement provided that a constant value of αs is used in the BFKL calculation. Moreover, the value of αs is in line with that extracted from measurements made at HERA.
