“…To avoid the tight constraints on new long-range forces, a "dark Higgs" S with a nonzero vacuum expectation value can give a nonzero mass to the A 0 . An A 0 with a sub-GeV mass can be probed at beam dumps and colliders, and with measurements of the muon anomalous magnetic moment, supernova cooling, and rare meson decays [140,[151][152][153][154][155][156][157][158][159][160][161][162][163][164][165][166]; see Fig. 12 and, e.g., [134] for a recent review.…”

“…The possibility of h → Z D Z D through Higgs-to-darkHiggs mixing or h → ZZ D through Z-Z D mass mixing (which is also induced by the above-mentioned kinetic mixing) was discussed in [177] and [165,166], respectively, with both occurring, for example, in hidden-valley models [32,135].…”

“…The phenomenology of a Z D with mass mixing to the Z has recently been discussed in [165,166,169,328] (see also, e.g., [31,167,177,329] for earlier work), including collider phenomenology of h → ZZ D , h → γZ D , and h → Z D Z D decays, as well as low energy constraints from colliders and fixed-target experiments, g − 2 of the muon and electron, rare meson decays, and electroweak precision observables (see Sec. XI for the h → Z D Z D mode).…”

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].

We examine the possibility that dark matter may be the manifestation of dark forces of a hidden sector, i.e. "Dark Force = Dark Matter." As an illustrative and minimal example we consider the hidden SU (2) h × U (1) h gauge group. The hidden dynamics is indirectly coupled to the Standard Model (SM) through kinetic mixing of U (1) h with the U (1)Y of hypercharge. We assume a hidden symmetry breaking pattern analogous to that of the SM electroweak symmetry, augmented with an extra scalar that allows both the "hidden Z boson" Z h and the "hidden photon" γ h to be massive. The "hidden W " bosons W ± h are dark matter in this scenario. This setup can readily accommodate a potential direct detection signal for dark matter at ∼ 10 GeV from CDMSII-Si data. For some choices of parameters, the model can lead to signals both in "dark matter beam" experiments, from Z h → W h W h , as well as in experiments that look for visible signals of dark photons, mediated by γ h . Other possible phenomenological consequences are also briefly discussed.

“…The present paper is the generalization of the previous works [47][48][49], were various aspects of phase transitions in s-wave holographic superconductor theory with ordinary matter sector coupled to the dark matter one have been elaborated. One expects that dark matter authorizes a part of a larger particle sector interacting with the visible matter and not completely decoupled [50][51][52][53][54][55].…”

Abstract:The holographic approach to building the p-wave superconductors results in three different models: the Maxwell-vector, the SU(2) Yang-Mills and the helical. In the probe limit approximation, we analytically examine the properties of the first two models in the theory with dark matter sector. It turns out that the effect of dark matter on the Maxwell-vector p-wave model is the same as on the s-wave superconductor studied earlier.For the non-Abelian model we study the phase transitions between p-wave holographic insulator/superconductor and metal/superconductor. Studies of marginally stable modes in the theory under consideration allow us to determine features of p-wave holographic droplet in a constant magnetic field. The dependence of the superconducting transition temperature on the coupling constant α to the dark matter sector is affected by the dark matter density ρ D . For ρ D > ρ the transition temperature is a decreasing function of α. The critical chemical potential µ c for the quantum phase transition between insulator and metal depends on the chemical potential of dark matter µ D and for µ D = 0 is a decreasing function of α.
