Top production at the Tevatron/LHC and nonstandard, strongly interacting spin one particles

In this note, we consider possible constraints from tt̄ production on the gauge bosons of theories with an extended strong interaction sector such as axigluons or flavour universal colorons. Such constraints are found to be competitive with those obtained from the dijet data. The current tt̄ data from the Tevatron rule out axigluon masses (mA) up to 900 GeV and 850 GeV at 2 σ and 4 σ levels respe...

34 th International Conference on High Energy Physics, Philadelphia, 2008 Nonstandard, strongly interacting spin one t¯t resonances.

Examining theories with an extended strong interaction sector such as axigluons or flavour universal colorons, we find that the constraints obtained from the current data on tt̄ production at the Tevatron are in the range of ∼ O TeV and thus competitive with those obtained from the dijet data. We point out that for large axigluon/coloron masses, the limits on the coloron mass may be different th...

Γγ Production of Non–strongly Interacting Susy Particles at Hadron Colliders

Non–strongly interacting supersymmetric particles – sleptons, charginos, neutralinos, and charged Higgs bosons – are difficult to detect at the Large Hadron Collider. We therefore examine the possibility of producing particles of this type in virtual γγ collisions at the LHC. Since photons can be emitted from protons which do not break up in the radiation process, very clean events can be gener...

Probing nonstandard top-quark couplings using spin correlation

Top spin correlation has been shown to be nontrivial in hadronic top-quark pair production, and can be realized by the asymmetries of the decay products of the top quark and antiquark. We show in this work that the top spin correlation is a sensitive probe to the anomalous top-quark couplings beyond the standard model. Specifically, we look at the anomalous chromomagnetic and chromoelectric dip...

Strongly Interacting Gauge Mediation at the LHC

Strongly interacting gauge mediation (SIGM) of supersymmetry breaking is very attractive, since it naturally predicts a light gravitino of mass < ∼O(10) eV, which causes no cosmological problem. We discuss various signatures of the SIGM in the early stage (a low integrated luminosity period) of the LHC experiments. We show, in particular, a possible way to discriminate it from the conventional ...
