Abstract:

We have searched for central production of a pair of photons with high transverse energies in pp̄ collisions at √s=1.8 TeV using 70pb-1 of data collected with the D0 detector at the Fermilab Tevatron in 1994-1996. If they exist virtual heavy pointlike Dirac monopoles could rescatter pairs of nearly real photons into this final state via a box diagram. We observe no excess of events above background and set lower 95% C.L. limits of 610 870 or 1580 GeV/c2 on the mass of a spin 0 1/2 or 1 Dirac monopole. © 1998 The American Physical Society.

Abstract:

This report describes the first search for top squark pair production in the channel (Formula presented)+jets+(Formula presented) using (Formula presented) pb(Formula presented) of data collected using the DØ detector. A 95% confidence level upper limit on (Formula presented) is presented. The limit is above the theoretical expectation for (Formula presented) for this process, but does show the sensitivity of the current DØ data set to a particular topology for new physics. © 1998 The American Physical Society.

Abstract:

We present a study of (Formula presented) production in (Formula presented) collisions at (Formula presented) from 97 (Formula presented) of data collected in the (Formula presented) (μμγ) decay channel with the D0 detector at Fermilab. The event yield and kinematic characteristics are consistent with the standard model predictions. We obtain limits on anomalous (Formula presented) and (Formula presented) couplings for form factor scales (Formula presented) and (Formula presented) Combining this analysis with our previous results yields 95% C.L. limits (Formula presented) (Formula presented) (Formula presented) and (Formula presented) for a form factor scale (Formula presented). © 1998 The American Physical Society.
