National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract The high mass spectrum of lepton and photon pairs is sensitive to a broad array of new physics. Examples include searches for extra dimensions in the dielectron and diphoton channels. A direct search for electron compositeness is possible in the production of excited electrons decaying into an electron and a photon. In addition, the electron plus missing transverse energy data sample can be searched for a W boson. Latest results in searches in the high mass dielectron, diphoton, electron plus photon, and electron plus missing transverse energy channels obtained by the DO experiment at the Tevatron are reported, using a data set corresponding to an integrated luminosity of about 1 fb.1. Since no significant excess is observed in the data in all cases, limits are set which improve on previous searches.
