“…In any case, more important is for the assignment of the [M V , λ HV V ] set to lead to a DM scattering cross section over nucleons below the exclusion limit given presently by the XENON1T experiment [33]. DM annihilation through CP-even boson exchange, being s-wave dominated, can be probed also through indirect detection but the corresponding limits are subdominant compared to the direct detection ones.…”

The Higgs-portal for vector dark matter and the effective field theory approach: A reappraisal

2020

We reanalyze the effective field theory approach for the scenario in which the particles that account for the dark matter (DM) in the universe are vector states that interact only or mainly through the Standard Model-like Higgs boson observed at the LHC. This model-independent and simple approach, with a minimal set of new input parameters, is widely used as a benchmark in DM searches and studies in astroparticle and collider physics. We show that this effective theory could be the limiting case of ultraviolet complete models, taking as an example the one based on a spontaneously broken U(1) gauge symmetry that incorporates a dark gauge boson and an additional scalar that mixes with the standard Higgs boson. Hence, despite the presence of the new degrees of freedom, measurements of the invisible decay branching ratio of the Higgs boson, as performed at colliders such as the CERN LHC, can be interpreted consistently in such an effective framework and can be made complementary to results of DM searches in direct detection experiments.Particle physics proposes a compelling solution to the puzzle of the missing or dark matter (DM) in the Universe, in terms of a colorless and electrically neutral weakly interacting massive particle (WIMP) that is stable at cosmological times and has a mass in the vicinity of the electroweak scale. Such WIMPs are predicted in many extensions of the Standard Model (SM); for reviews, see Refs. [1,2] for instance. A very interesting class of such models is the one in which the DM states interact only through their couplings with the Higgs sector of the theory, the so-called Higgs-portal DM models; see Ref.[3] for a recent review. The observed cosmological relic abundance would be induced when pairs of DM states annihilate into SM fermions and gauge bosons, through the s-channel exchange of the Higgs bosons, and the latter will in turn be the mediators of the mechanisms that allow for the experimental detection of the DM states.The simplest of the Higgs-portal scenarios is when the Higgs sector is minimal and, thus, identical to the SM one, namely a single doublet Higgs field structure that leads to the unique H boson observed so far [4,5]. One could then minimally extend the model by simply adding one new particle, the DM state, as an isosinglet under the electroweak group. Nevertheless, the DM particle can have the three possible spin assignments and be a scalar, a vector or a Dirac or Majorana spin-1 2 fermion. Although only effective, this approach can be adopted as it is rather model-independent and does not make any assumption on the very nature of the DM [6-15]. Furthermore, it bears the advantage of having a very restricted number of extra parameters in addition to the SM ones [16], namely the mass of the DM particle and its coupling to the Higgs boson.Such a minimal scheme has been investigated extensively and has been probed in direct and indirect detection in astrophysical experiments, and at colliders such as the CERN LHC. In the latter case, light DM particles are searched for...

Fermion dark matter and radiative neutrino masses from spontaneous lepton number breaking

et al. 2020

View full text Add to dashboard Cite

In this paper, we study the viability of having a fermion Dark Matter particle below the TeV mass scale in connection to the neutrino mass generation mechanism. The simplest realisation is achieved within the scotogenic model where neutrino masses are generated at the 1-loop level. Hence, we consider the case where the dark matter particle is the lightest  2 -odd Majorana fermion running in the neutrino mass loop. We assume that lepton number is broken dynamically due to a lepton number carrier scalar singlet which acquires a non-zero vacuum expectation value. In the present scenario the Dark Matter particles can annihilate via t-and s-channels. The latter arises from the mixing between the new scalar singlet and the Higgs doublet. We identify three different Dark Matter mass regions below 1 TeV that can account for the right amount of dark matter abundance in agreement with current experimental constraints. We compute the Dark Matter-nucleon spin-independent scattering crosssection and find that the model predicts spin-independent cross-sections 'naturally' dwelling below the current limit on direct detection searches of Dark Matter particles reported by XENON1T. c 2Theoretically, it is very tempting to think that the DM sector and neutrino mass generation mechanism are linked. This connection appears naturally when the neutrino masses are generated at the loop level [14]. In such scenarios, the smallness of the neutrino masses is due to a loop suppression and the additional particles carry a non-trivial charge under an unbroken symmetry which is responsible for DM stability. The simplest idea in this regard is the so-called Scotogenic model [14], where the neutrino masses are generated at the 1-loop level. In this OPEN ACCESS RECEIVED

“…Dark matter is understood to be an heavy particle beyond standard particle physics (Bertone & Tait 2018). However, the lack of direct detection of such a particle (Akerib et al (2017); Aprile et al (2018)) is increasingly favouring alternative candidates, like QCD axions and ultra-light axions (Schive et al (2014); Capolupo (2016); De ; Capolupo (2018); Capolupo et al (2019)), having very light masses, and being able to explain the small scale features of dwarf galaxies (Moore 1994). Albeit dark matter is still favoured over more exotic alternative, one should also mention that there is another vi-⋆ E-mail: ivan.demartino1983@gmail.com able way to solve the puzzle.…”

The lack of detection of supersymmetric particles is leading to look at alternative avenues for explaining dark matter's effects. Among them, modified theories of gravity may play an important role accounting even for both dark components needed in the standard cosmological model. Scalar-Tensor-Vector Gravity theory has been proposed to resolve the dark matter puzzle. Such a modified gravity model introduces, in its weak field limit, a Yukawa-like correction to the Newtonian potential, and is capable to explain most of the phenomenology related to dark matter at scale of galaxies and galaxy clusters. Nevertheless, some inconsistencies appears when studying systems that are supposed to be dark matter dominated such as dwarf galaxies. In this sense Antlia II, an extremely diffuse galaxy which has been recently discovered in Gaia's second data release, may serve to probe the aforementioned theory against the need for invoking dark matter. Our analysis shows several inconsistencies and leads to argue that MOdified Gravity may not be able to shed light on the intriguing nature of dark matter.
