Search for a 33.9 MeV/c^2 Neutral Particle in Pion Decay

J. A. Formaggio, E. D. Zimmerman, T. Adams +41

The E815 (NuTeV) neutrino experiment has performed a search for a 33.9 MeV/c^2 weakly-interacting neutral particle produced in pion decay. Such a particle may be responsible for an…

Hard Single Diffraction in pbarp Collisions at root-s = 630 and 1800 GeV

The D0 Collaboration, B. Abbott

Using the D0 detector, we have studied events produced in proton-antiproton collisions that contain large forward regions with very little energy deposition (``rapidity gaps'') and…

The Isolated Photon Cross Section in p pbar Collisions at sqrt(s) = 1.8 TeV

D0 Collaboration, B. Abbott

We report a new measurement of the cross section for the production of isolated photons, with transverse energies (ET) above 10 GeV and pseudorapidities |eta| < 2.5, in p pbar coll…

A Measurement of the W to tau+nu Production Cross Section in p-pbar Collisions at sqrt(s) = 1.8 TeV

D0 Collaboration, B. Abbott

We report on a measurement of sigma(p-pbar to W+X) times B(W to tau+nu) in p-pbar collisions at sqrt(s) = 1.8 TeV at the Fermilab Tevatron. The measurement is based on an integrate…

Limits on Anomalous WWgamma and WWZ Couplings from WW/WZ->enujj Production

D0 collaboration, B. Abbott, M. Abolins

Limits on anomalous WWgamma and WWZ couplings are presented from a study of WW/WZ->enujj events in ppbar collisions at sqrt{s}=1.8 TeV. Results from the analysis of data collected…

Probing BFKL Dynamics in the Dijet Cross Section at Large Rapidity Intervals in ppbar Collisions at sqrt{s}=1800 and 630 GeV

D0 Collaboration, B. Abbott

Inclusive dijet production at large pseudorapidity intervals (delta_eta) between the two jets has been suggested as a regime for observing BFKL dynamics. We have measured the dijet…
