We propose an extension of the Standard Model by extending the EW
symmetry to SU(2)L×U(1)×Z2 and introducing three SU(2)×U(1) singlet right
handed neutrinos and an additional Higgs doublet. While the SM gauge bosons
and the quarks and charged leptons acquire masses from the spontaneous
breaking of SU(2)L × U(1) symmetry at the electroweak scale, the neutrinos
acquire masses from the...

Supersymmetry breaking by constant superpotentials localized at boundaries is studied
in a supersymmetric warped space model. By taking into account of the radion and the
compensator supermultiplets, as well as the bulk mass for the hypermultiplet, we show
that the radius is stabilized by the presence of the constant boundary
superpotentials. We then give the masses of the hypermultiplet,...

Extensions of the MSSM often predict the existence of new fermions
and their scalar superpartners which are vectorlike with respect to the
standard model gauge group but may be chiral under additional gauge factors.
In this paper we explore the production and decay of an important example, i.e.,
a heavy isosinglet charge -1/3 quark and its scalar partner, using the charge
assignments of a...

Multiple point principle (MPP) postulates the existence of as many phases with the
same energy density as possible, which are allowed by a given theory. Being applied
to the non--supersymmetric two-Higgs doublet extension of the Standard Model (SM) MPP
leads to the invariance of the quartic part of the Higgs effective potential and
Yukawa interactions between Higgs doublets and fermions...

Contact interactions offer a general framework for describing a new interaction
with scale above the sqrt(s). These interaction can occur if the SM particles are
composite or if new heavy particles are exchanged. We present results in the
dimuon and dijet final states employing ratios for startup (100pb-1) and
asymptotic reach.

We present trigger methodologies for alternative
signatures at the LHC. They include long lived
states and mutliobject particle topologies as well as
express line triggers for monitoring at startup.
