Observing an invisible Higgs boson
Given its weak coupling to bottom quarks and tau leptons, the Higgs boson may predominantly decay into invisible particles like gravitinos, neutralinos, or gravitons. We consider the manifestation of such an invisibly decaying Higgs boson in weak boson fusion at the CERN LHC. Distinctive kinematic distributions of the two quark jets of the signal as compared to Zjj and Wjj backgrounds allow to ...
متن کاملPhenomenology of a leptonic goldstino and invisible Higgs boson decays
Non-linearly realized supersymmetry, combined with the Standard Model field content and SU(3) × SU(2) × U(1) gauge invariance, permits local dimension-six operators involving a goldstino, a lepton doublet and a Higgs doublet. These interactions preserve total lepton number if the left-handed goldstino transforms as an antilepton. We discuss the resulting phenomenology, in the simple limit where...
متن کاملSearch for an Invisible Decaying Higgs Boson in Dilepton Events at CDF
We present the first search at the Tevatron for a Higgs boson decaying to an invisible final state. We use the full CDF Run II data set corresponding to 9.7 fb−1 of integrated luminosity. We search in the associated ZH production mode and require two same-flavor, oppositely charged leptons and a significant value of missing transverse energy to be in the final state. We exclude values of σZH×B ...
متن کاملCan an invisible Higgs boson be seen via diffraction at the LHC ?
We study the possibility of observing an ‘invisible’ Higgs boson in central exclusive diffractive production at the LHC. We evaluate the cross section using, as a simple example, the Standard Model with a heavy fourth generation, where the invisible decay mode H → ν4ν̄4 dominates, with the heavy neutrino mass M(ν4) ≃ 50 GeV. We discuss the possible requirements on trigger conditions and the back...
متن کاملVisible Supersymmetry Breaking and an Invisible Higgs
If there are multiple hidden sectors which independently break supersymmetry, then the spectrum will contain multiple goldstini. In this paper, we explore the possibility that the visible sector might also break supersymmetry, giving rise to an additional pseudogoldstino. By the standard lore, visible sector supersymmetry breaking is phenomenologically excluded by the supertrace sum rule, but t...
