~\ CiteBaek:2014 jga, we go over the undetectable Higgs decay size Γ_h^inv in the Higgs portal vector dark matter model at the limit m_V →0^+. Such a distinction in the habits of Γ_h^inv in the massless VDM restriction shows another restriction of EFT for Higgs portal VDM, and the significance of renormalizable and gauge-invariant models for the Higgs portal VDM. The boosting empirical pressure on the standard cosmological model encourages analyses surpassing the standard of the collision-less cold dark matter. We take into consideration inelastic dark matter circumstances with dark photon moderator and a dark Higgs boson. The dark Higgs boson automatically breaks the gauge proportion connected with the dark photon, and provides the mass to the dark photon and the mass distinction to dark fragments. In the context of a two-Higgs doublet model, supplemented by an extra light pseudoscalar Higgs boson and a steady isosinglet fermion, we consider the possibility of attending to simultaneously the discrepancy between the conventional assumption of the strange magnetic minute of the muon recently measured at Fermilab and the longstanding problem of the dark matter in the cosmos which can be made up by a thermal weakly engaging huge bit. We discover an evaluated U_B-L expansion of the common model with the inclusion of 3 right-handed neutrinos of exotic B-L charges to cancel the gauge anomaly. The new bit range not only opens up a new home window for dark matter study but also satisfies the restraints from lepton taste going against decay of μ→e γ. We demonstrate how trinification models based upon the scale team SU_C ×SU_L ×SU_R recognized near the TeV scale can offer normally a selection of dark matter candidates. Below we develop the vector boson DM scenario in which the DM pairs off-diagonally with the vector-like fermions and normal fermions present in the theory.

We present converged ab initio calculations of structure aspects for elastic spin-dependent WIMP scattering off all centers utilized in dark matter direct-detection searches: ^19 F, ^23 Na, ^27 Al, ^29 Si, ^73 Ge, ^127 I, and ^129131 Xe. From a set of recognized two- and three-nucleon interactions derived within chiral efficient field theory, we create consistent WIMP-nucleon currents at the one-body degree, consisting of effects from axial-vector two-body currents. The raising empirical pressure on the common cosmological model encourages evaluations exceeding the paradigm of the collision-less cold dark matter. The ϕ field can contribute to the DM density and can couple all the matter species universally, consisting of extra hefty DM bits. We researched the dark matter phenomenology of Standard Model expansions resolving the reported abnormality in the R_K observable at one-loop. Additionally, dark matter direct detection experiments provide strict bounds even in cases where the dark matter prospect only contributes a small fraction of the observed dark matter energy thickness. We take into consideration inelastic dark matter situations with dark photon arbitrator and a dark Higgs boson. The dark Higgs boson spontaneously damages the scale proportion connected with the dark photon, and gives the mass to the dark photon and the mass difference to dark fragments. We checked out a gauged U_B-L extension of the common model with incorporation of 3 right-handed neutrinos of unique B-L charges to terminate the scale anomaly. The new bit range not just opens a new window for dark matter research, but also satisfies the restrictions from lepton taste breaking decay of μ→e γ. We demonstrate how trinification models based upon the scale group SU_C ×SU_L ×SU_R understood near the TeV range can offer naturally a selection of dark matter prospects. Below we develop the vector boson DM circumstance in which the DM couples off-diagonally with the vector-like fermions and normal fermions present in the theory.

The measurement of the triple gauge combinings is a central part of diboson research at the LHC. We reveal the importance of NNLO+PS accuracy for the νν ¯ γ background to photon plus missing energy trademarks in dark-matter searches, and we compare MiNNLOPS forecasts for νν ¯ γ manufacturing to recent 13 TeV information. In spite of the reality that dark matter constitutes among the foundations of the conventional cosmological paradigm, its presence has up until now just been presumed from astronomical monitorings, and its tiny nature stays evasive. Academic debates recommend that dark matter may be attached to the symmetry-breaking mechanism of the electroweak interactions or of various other proportions, expanding the Standard Model of fragment physics. Abstract We study the dark matter phenomenology of scotogenic frameworks via an instead illustrative model prolonging the Standard Model by scalar and fermionic singlets and doublets. Abstract An axion turning in space can produce dark photons in the early cosmos via tachyonic instability. This situation provides a unique background for dark photon dark matter. In this paper we check out the μ discrepancy in the context of the R-parity conserving next-to-minimal supersymmetric Standard Model plus right-handed neutrinos superfields. The model has the capacity to replicate neutrino physics information and includes the interesting opportunity to have the right-handed sneutrino as the lightest supersymmetric particle and a practical dark matter prospect. Warm dark matter fragments with masses in the keV array have been related to the big team representations in gauge concepts via a high number of varieties at decoupling. We isolate a model that normally accommodates both the conventional model representation and the fermionic dark matter in arrangement with both small and large constraints.
