The Higgs model is generalized so that in addition to the radial Higgs field there are fields which correspond to the themasy and entropy. The model is further generalized to include state and sign parameters. A reduction to the standard Higgs model is given and how to break symmetry using a nonzero VEV (vacuum expectation value) is shown. A ’fluid rotation’ can be performed on the standard Hig...

Searches for Beyond Standard Model (BSM) Higgs bosons at the CMS experiment are presented. The analyses are based on proton-proton collision data recorded by the CMS experiment at the LHC at CERN at 7 TeV and 8 TeV centre-of-mass energies in the years 2011 and 2012 respectively, corresponding to an integrated luminosity of up to 25 fb−1. No evidence for additional Higgs bosons other than the 12...

A new scalar resonance, called the radion, with couplings to fermions and bosons similar to those of the Higgs boson, is predicted in the framework of Randall-Sundrum models, proposed solutions to the hierarchy problem with one extra dimension. An important distinction between the radion and the Higgs boson is that the radion would couple directly to gluon pairs, and in particular its decay pro...

In this talk preliminary results of Higgs boson searches at LEP2 up to centre-of-mass energies of 183 GeV have been summarised. The main topics are searches for the Minimal Standard Model (MSM) Higgs boson and searches for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM). No indication for Higgs production has been found. The experiments have published their Higgs search...

Self-dual vortex solutions are studied in detail in the generalized abelian Higgs model with independent Chern-Simons interaction. For special choices of couplings, it reduces to a Maxwell-Higgs model with two scalar fields, a Chern-Simons-Higgs model with two scalar fields, or other new models. We investigate the properties of the static solutions and perform detailed numerical analyses. For t...

We investigate Higgs boson pair production at hadron colliders for Higgs boson masses mH<140 GeV and the rare decay of one of the two Higgs bosons. While in the standard model the number of events is quite low at the CERN Large Hadron Collider ~LHC!, a first, albeit not very precise, measurement of the Higgs boson self-coupling is possible in the gg→HH→bb̄gg channel. A luminosity-upgraded LHC co...

A light CP-even Higgs boson withmh ∼ 10 GeV could explain the recent BNL measurement of the muon anomalous magnetic moment, in the framework of a general two-Higgs-doublet extension of the Standard Model. However, the allowed Higgs mass window is quite small and the corresponding model parameters are very constrained. The Higgs sector can contribute significantly to the observed BNL result for ...

We analyze the effect of flat universal extra dimensions (i.e., extra dimensions accessible to all SM fields) on the process b → sγ. With one Higgs doublet, the dominant contribution at one-loop is from Kaluza-Klein (KK) states of the charged would-be-Goldstone boson (WGB) and of the top quark. The resulting constraint on the size of the extra dimension is comparable to the constraint from T pa...

Theoretical frameworks beyond the standard model predict a rich Higgs sector with multiple charged and neutral Higgs bosons. Both the CDF II and DØ experiments at the Tevatron have analyzed 1 fb−1 of pp̄ collisions at √ s = 1.96TeV in search of Higgs boson production. A complete suite of results on searches for neutral, charged, and fermiophobic Higgs bosons limit the allowed production rates an...
