Observation of diffractive b-quark production at the fermilab tevatron

Published

Journal Article

We report a measurement of the fraction of b quarks produced diffractively in ⊯pp collisions at √ s = 1.8 TeV. Diffraction is identified by the absence of particles in a forward pseudorapidity region. From events with an electron of transverse momentum 9.5 < peT< 20 GeV/c within the pseudorapidity region |η| < 1.1, the ratio of diffractive to total b-quark production rates is found to be R⊯bb= [0.62 ± 0.19(stat) ± 0.16(syst)]%. This result is comparable in magnitude to corresponding ratios for W and dijet production but significantly lower than expectations based on factorization. © 2000 The American Physical Society.
