Description
The high-mass spectrum of lepton and photon pairs is sensitive to a broad
array of new physics. Examples are searches for extra dimensions in different
models in the dielectron, dimuon, and diphoton channels, and Z´ bosons with
Standard-Model-like couplings to fermions as well as in a variety of GUT-
inspired models. A direct search for electron compositeness is possible in the
production of excited electrons decaying into electron and photon. In addition,
the electro (or muon) plus missing ET data sample can be searched for a W´
boson. We report on the latest results in searches in the high mass dielectron,
dimuon, diphoton, electron plus photon, and electron plus missing ET channels
obtained by the D0 experiment at the Tevatron, using a data set corresponding
to an integrated luminosity of about 1 fb^-1, and in most cases substantially
exceeding the reach of previous searches.
