Inert Doublet Dark Matter with an additional scalar singlet and 125 GeV Higgs Boson
In this work we consider a model for particle dark matter where an extra inert Higgs doublet and an additional scalar singlet is added to the Standard Model (SM) Lagrangian. The dark matter candidate is obtained from only the inert doublet. The stability of this one component dark matter is ensured by imposing a Z2 symmetry on this additional inert doublet. The additional singlet scalar has a v...
متن کاملSupersymmetric exotic decays of the 125 GeV Higgs boson.
We reveal a set of novel decay topologies for the 125 GeV Higgs boson in supersymmetry which are initiated by its decay into a pair of neutralinos, and discuss their collider search strategies. This category of exotic Higgs decays is characterized by the collider signature: visible objects+E_{T}, with E_{T} dominantly arising from escaping dark matter particles. Their benchmark arises naturally...
متن کامل[in2p3-00705410, v1] SUSY and a 125 GeV Scalar
An excess of events at a mass of ∼ 125 GeV has been reported by both ATLAS and CMS collaborations using 5 fb−1 of data. If this excess of events is confirmed by further searches with more data, it will have extremely important consequences in the context of supersymmetric extensions of the Standard Model. We show that for a Standard Model like Higgs boson with a mass 122.5 < Mh < 127.5 GeV, sev...
متن کاملEvidence for the direct decay of the 125 GeV Higgs boson to fermions
The discovery of a new boson with a mass of approximately 125GeV in 2012 at the Large Hadron Collider1–3 has heralded a new era in understanding the nature of electroweak symmetry breaking and possibly completing the standard model of particle physics4–9. Since the first observation in decays to γγ, WW and ZZ boson pairs, an extensive set of measurements of the mass10,11 and couplings to W and ...
متن کاملEvidence for the 125 GeV Higgs boson decaying to a pair of τ leptons
A search for a standard model Higgs boson decaying into a pair of tau leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 inverse femtobarns at a centre-of-mass energy of 7 TeV and 19.7 inverse femtobarns at 8 TeV. Each tau lepton decays hadronically or leptonically to an electron or a muon, lea...
