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...

393. Contact Interactions at the LHC

Parallel Talk

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.
