Identifying the contributions of Universal Extra Dimensions in the Higgs sector at linear e + e − colliders

چکیده
We study the dilepton-dijet signal in the dominant Higgs production channel at a linear e+e− collider. We estimate the effects of Universal Extra Dimension (UED) by a simple analysis of the cross-sections. The heavy Kaluza-Klein excitations of the Standard Model fields in UED can significantly alter the decay properties of the Higgs boson to loop-driven final states. We show that by taking a simple ratio between cross-sections of two different final states this difference can be very easily highlighted.

Identifying new physics contributions in the Higgs sector at linear e+e− colliders
Loop driven decay modes of the Higgs are sensitive to new physics contributions because of new particles in the loops. To highlight this we look at the dilepton-dijet signal in the dominant Higgs production channel at a linear ee collider. We show that by taking a simple ratio between cross-sections of two different final states such contributions can be very easily identified.
متن کاملCharged Higgs production at linear colliders in large extra dimensions
Abstract In the Two-Higgs-Doublet Model(2HDM) with large extra dimensions(LED), we study the contributions of virtual Kaluza-Klein(KK) gravitons to 2HDM charged Higgs production, especially in the two important production processes e+e− → H+H− and e+e− → Htb̄, at future linear colliders (LC). We find that KK graviton effects can significantly modify these total cross sections and also their diff...
متن کاملKaluza - Klein Effects on Higgs Physics in Universal Extra Dimensions
We examine the virtual effects of Kaluza-Klein (KK) states on Higgs physics in universal extra dimension models. We study the partial widths Γh→gg, Γh→γγ , and Γh→γZ , which are relevant for Higgs production and detection in future collider experiments. These interactions occur at one loop in the Standard Model, as do the KK contributions. We find that the deviations induced by the KK exchanges...
متن کاملExtra Dimensions and Higgs Pair Production at Photon Colliders
We show that new physics effects due to extra dimensions can dramatically affect Higgs pair production at photon colliders. We find that the cross section due to extra dimensions with the scale MS of new physics around 1.5 TeV, the cross section can be as large as 0.11 pb (1.5pb) for monochromatic photon collision, γγ → HH, with the collider energy √ s = 0.5(1) TeV for Higgs mass of 100 (350) G...
