Description
The large mass of the top quark, close to the electroweak symmetry-breaking
scale, makes it a good candidate for probing physics beyond the Standard
Model. Single top quarks may be produced in the decay of a new heavy gauge
boson W' and we present limits on the production cross section and
the mass of such a W' assuming standard model like couplings. We
also search for single top productions through flavor changing neutral currents
involving gluon, Z boson, or photon exchange. We also search for non standard
model signatures in top pair events. Models for new physics beyond the
standard model are probed by looking at possible different event kinematics or
deviations in the measured total or differential cross section.
