The bottom quark production in the single diffractive dissociation is first observed in pp collisions at √8=1.8 TeV using the Collider Detector at Fermilab. The absence of an energy flow in the forward rapidity region ('rapidity gap') is used as an evidence of the single diffraction. The high-pt electron in the Et range of 9.5 < ETele < 20 GeV and the central rapidity region (μ＜1.1) are used to identify the bottom quark decay. The ratio of the diffractive to ...
