“…After 2 years, using the same analysis protocol, we have carried out a new unblinding of ANAIS-112 data and the corresponding annual modulation analysis. While preparing a more complete analysis, we present here the result of a model independent analysis searching for modulation in the same regions as DAMA/LIBRA has published ( [1][2][3][4][5][6] keV and [2,6] keV) using an exposure of 220.69 kg×y. Data from all the modules are added together and we use a least-squared fit, modeling the data as: Figure 1.…”

ANAIS (Annual modulation with NaI Scintillators) is a dark matter direct detection experiment located at the Canfranc Underground Laboratory (LSC), in Spain. The goal is to confirm or refute in a model independent way the DAMA/LIBRA positive result: an annual modulation in the low-energy detection rate compatible with the expected signal induced by dark matter particles in the galactic halo. This signal, observed for about 20 years, is in strong tension with the negative results of other very sensitive experiments, but a direct comparison using the same target material, NaI(Tl), was still lacking. ANAIS-112, consisting of 112.5 kg of NaI(Tl) scintillators, is taking data at the LSC since August 2017. Here we present the preliminary annual modulation analysis corresponding to two years of data (exposure of 220.69 kg×y) and the ANAIS-112 projected sensitivity for the scheduled 5 y of operation.

“…which has a potential to be verified in the DM direct detection experiments [56]. It is also easy to check that through their couplings with the SM fermions (13) and (14), the dark gauge bosons can decay before the BBN epoch.…”

Quasi-degenerate dark matter for DAMPE excess and 3.5 keV line

We propose a quasi-degenerate dark matter scenario to simultaneously explain the 1.4 TeV peak in the high-energy cosmic-ray electron-positron spectrum reported by the DAMPE collaboration very recently and the 3.5 keV X-ray line observed in galaxies clusters and from the Galactic centre and confirmed by the Chandra and NuSTAR satellites. We consider a dark SU (2) ′ × U (1) ′ gauge symmetry under which the dark matter is a Dirac fermion doublet composed of two SU (2) ′ doublets with non-trivial U (1) ′ charges. At one-loop level the two dark fermion components can have a mass split as a result of the dark gauge symmetry breaking. Through the exchange of a mediator scalar doublet the two quasi-degenerate dark fermions can mostly annihilate into the electron-positron pairs at tree level for explaining the 1.4 TeV positron anomaly, meanwhile, the heavy dark fermion can very slowly decay into the light dark fermion with a photon at one-loop level for explaining the 3.5 keV X-ray line. Our dark fermions can be also verified in the direct detection experiments. PACS numbers: 95.35.+d, 12.60.Cn, 12.60.Fr

“…We have no prediction on mass in this case yet, but the experiment gives us constraints on the WIMP-neutron scattering cross-section correlating dark matter particle mass. In the next figure 3 we can see data of 2017 year [13]. Upper limits on the spin-independent WIMP-nucleon scattering cross-section set by current leading experiments.…”

Abstract. In this paper authors present review of neutralino research results in LHC, cosmological observations and theoretical models. Nowdays there are constraints on the mass of dark matter particle from experiments. The neutralino as a candidate for the dark matter particle in the framework of supersymmetry is considered. There are some discuss advantages for it about the NMSSM model. The properties of neutralino are functions of free parameters of the model. In agreement with the foregoing, constraints on free parameters of the NMSSN are determined.
