Beyond the Standard Model
The large hadron collider will begin physics operation late this year,
and will provide a decisive test of more than 30 years of building
models for physics beyond the standard model. This talk will
critically review the case for physics beyond the standard model
arising from present-day data, and ways of distinguishing them at the
LHC. Emphasis will be placed on strong electroweak...

Beyond the Standard Model
We report on searches for the production of scalar and vector
leptoquarks in ppbar collisions at the Tevatron collider,
which are based on integrated luminosities of up to
2.5 fb-1 collected with the DO detector. Leptoquarks,
which are predicted by several extensions of the Standard
Model, are hypothetical particles carrying both lepton and
quark flavors. At hadron colliders they can...

Beyond the Standard Model
Dilepton-jet final states are used to study physical phenomena not predicted by the standard model. ATLAS discovery potential to leptoquarks and Majorana neutrinos is presented with fully-simulated ATLAS detector at the Large Hadron Collider (LHC) at
CERN. The study is motivated by the role of the leptoquark in the Grand Unification of fundamental forces and the see-saw mechanism that...

Beyond the Standard Model
We report on searches for a compositeness signature of quarks
and leptons in the di-fermion (di-leptons and di-jets) channels
using data collected by the D0 detector at the Fermilab Tevatron.
We set model-dependent lower limits at the 95% condence level on
the compositeness scale of for constructive and destructive
interference between the Drell-Yan (DY) amplitude and the contact...

Beyond the Standard Model
We re-examine constraints from the evidence for
observation of the lifetime difference in $D^0$-${\overline D}^0$
mixing on the parameters of supersymmetric models with $R$-parity violation (RPV). We find that RPV SUSY can give large negative contribution to the
lifetime difference. We also discuss the importance of the choice of
weak or mass basis when placing the constraints on...

Beyond the Standard Model
A review of the discovery potential of the LHC for exotic phenomena involving complex final states is presented. Topics covered include searches for high mass di-boson resonances, fourth generation quarks, technicolor, black-holes etc. Challenges presented by unconventional final states involving long-lived particles predicted by hidden valley and other models are also discussed. The...

Beyond the Standard Model
To begin exploring the possibility that leptons, quarks, or both, might be highly relativistic bound states, a numerical method for solving two-body, bound-state Bethe-Salpeter equations is discussed. This class of integral equations is difficult to solve, not because the equations are usually non-separable, but rather because it is typically impossible to discretize the equations in such...

Beyond the Standard Model
We go beyond the Standard Model guided by presymmetry, the discrete electroweak quark-lepton symmetry hidden by topological effects which explain quark fractional charges as in condense matter physics. Partners of the particles of the Standard Model and the discrete symmetry associated with this partnership appear as manifestations of a residual presymmetry and its extension from matter to...
