“…These signatures offer opportunities for LHCb [76,77] as well as ATLAS and CMS, but we do not cover them here.

“…An example of a natural theory where such particles may arise in Higgs decays [76] is the twin Higgs [226], though the details are still to be worked out.

Exotic decays of the 125 GeV Higgs boson

We perform an extensive survey of nonstandard Higgs decays that are consistent with the 125 GeV Higgs-like resonance. Our aim is to motivate a large set of new experimental analyses on the existing and forthcoming data from the Large Hadron Collider (LHC). The explicit search for exotic Higgs decays presents a largely untapped discovery opportunity for the LHC collaborations, as such decays may be easily missed by other searches. We emphasize that the Higgs is uniquely sensitive to the potential existence of new weakly coupled particles and provide a unified discussion of a large class of both simplified and complete models that give rise to characteristic patterns of exotic Higgs decays. We assess the status of exotic Higgs decays after LHC run I. In many cases we are able to set new nontrivial constraints by reinterpreting existing experimental analyses. We point out that improvements are possible with dedicated analyses and perform some preliminary collider studies. We prioritize the analyses according to their theoretical motivation and their experimental feasibility. This document is accompanied by a Web site that will be continuously updated with further information [http://exotichiggs.physics .sunysb.edu].

“…This scenario is depicted in the middle panel of figure 5. The CMS 9 Searches for displaced vertices and long lived particles decaying inside the detector are currently ongoing at the LHC (see for example [21]) and were performed at the Tevatron [22][23][24][25][26], but there is still no systematic coverage of all the possible lifetimes and final states. We will ignore this possibility in what follows, even though experimentally it is intriguing and could be the subject of a dedicated study.…”

A large enhancement of a factor of 1.5 -2 in Higgs production and decay in the diphoton channel, with little deviation in the ZZ channel, can only plausibly arise from a loop of new charged particles with large couplings to the Higgs. We show that, allowing only new fermions with marginal interactions at the weak scale, the required Yukawa couplings for a factor of 2 enhancement are so large that the Higgs quartic coupling is pushed to large negative values in the UV, triggering an unacceptable vacuum instability far beneath the 10 TeV scale. An enhancement by a factor of 1.5 can be accommodated if the charged particles are lighter than 150 GeV, within reach of discovery in almost all cases in the 8 TeV run at the LHC, and in even the most difficult cases at 14 TeV. Thus if the diphoton enhancement survives further scrutiny, and no charged particles beneath 150 GeV are found, there must be new bosons far beneath the 10 TeV scale. This would unambiguously rule out a large class of fine-tuned theories for physics beyond the Standard Model, including split SUSY and many of its variants, and provide strong circumstantial evidence for a natural theory of electroweak symmetry breaking at the TeV scale. Alternately, theories with only a single fine-tuned Higgs and new fermions at the weak scale, with no additional scalars or gauge bosons up to a cutoff much larger than the 10 TeV scale, unambiguously predict that the hints for a large diphoton enhancement in the current data will disappear.

“…In our case we expect 7 The search [52] performed a similar analysis on the final states the decays into Z and Higgs bosons to dominate over the photon channel. Displaced vertices from the decay Z → e − e + have been searched at the D0 experiment [47]. The bounds strongly depend on the lifetime of the NLSP and the tightest bound from D0 is around 1 pb for cτ 0.2 m. 8 In lopsided gauge mediation only electroweak particles are accessible at the TeVatron, yielding a total cross-section for χ 0 1 production at most of about 1 pb for µ 100 GeV.…”

It has been recently pointed out that the unavoidable tuning among supersymmetric parameters required to raise the Higgs boson mass beyond its experimental limit opens up new avenues for dealing with the so called µ-B µ problem of gauge mediation. In fact, it allows for accommodating, with no further parameter tuning, large values of B µ and of the other Higgs-sector soft masses, as predicted in models where both µ and B µ are generated at one-loop order. This class of models, called Lopsided Gauge Mediation, offers an interesting alternative to conventional gauge mediation and is characterized by a strikingly different phenomenology, with light higgsinos, very large Higgs pseudoscalar mass, and moderately light sleptons. We discuss general parametric relations involving the fine-tuning of the model and various observables such as the chargino mass and the value of tan β. We build an explicit model and we study the constraints coming from LEP and Tevatron. We show that in spite of new interactions between the Higgs and the messenger superfields, the theory can remain perturbative up to very large scales, thus retaining gauge coupling unification.
