Diffraction at Tevatron Run II from DO.
Abstract
The Forward Proton Detector (FPD) is a new sub-detector of the DO detector at the Fermilab Tevatron. The FPD is used to tag and measure protons and antiprotons, allowing access to a wide range of diffractive and elastic scattering physics. It consists of momentum spectrometers which make use of accelerator magnets along with points measured on the track of scattered protons and antiprotons to calculate their momenta and scattering angle. Tracks are measured using scintillating fiber detectors located in vacuum chambers positioned in the Tevatron tunnel 20--60 meters upstream and downstream of the central DO detector. Another method to select diffractive events is to use the forward rapidity gap selection ensuring that there is no energy exchange between the scaterred jets and the (anti)proton remnants. Preliminary results using both methods will be presented together with the latest results from Run I, as well as prospects of measurements to be performed.
