We describe a class of models called ``hidden valleys'', which consist of low mass
hidden sector quarks charged under a new confining gauge group. Such sectors arise
often in string theories and elsewhere. The phenomenology of these sectors is often
qualitatively different from other beyond the standard model physics, giving rise to
long lived hidden sector hadrons, high invariant mass...

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...

We report on searches for the production of scalar and vector leptoquarks in
$p\bar{p}$ collisions at the Tevatron collider, which are based on integrated
luminosities of up to 1\,fb$^{-1}$ collected with the D\O{} detector.
Leptoquarks, which are predicted by several extensions of the Standard Model,
are hypothetical particles carrying both lepton and
quark flavors. At hadron...

We propose a renormalizable (susy) grand unified theory
where the neutrino masses are generated through type III
and type I seesaw mechanisms. Several phenomenological
and cosmological aspects of this proposal are discussed.

We present the results of a model-independent search for new physics, conducted on
1fb-1 of data collected by the CDF experiment at the Fermilab Tevatron.
A novel technique (Vista) is used to analyse the bulk features of the high-pT data.
Event populations and approximately 17,000 kinematic distributions from 340 distinct
final states are searched for signs of physics beyond the Standard Model.

Lacking precise theoretical direction for where to look for the first sign of physics
beyond the Standard Model, it seems prudent to look in as many places as possible.
Sleuth is a quasi-model-independent search strategy for new electroweak scale
physics, appropriate for frontier energy hadron colliders. Assuming the new physics
appears in the form of structure with characteristic energy...
