“…The L-shell cosmogenics are relevant from ∼ 0.5-1.7 keVee, where the dark matter signal is expected to dominate. The dominant contribution in the first year of running comes from 68 Ge, followed by 65 Zn.…”

A CoGeNT modulation analysis

et al. 2012

We analyze the recently released CoGeNT data with a focus on their time-dependent properties. Using a variety of statistical tests, we confirm the presence of modulation in the data, and find a significant component at high (E ee > ∼ 1.5 keVee) energies. We find that standard elastic WIMPs in a Maxwellian halo do not provide a good description of the modulation. We consider the possibility of non-standard halos, using halo independent techniques, and find a good agreement with the DAMA modulation for Q Na ≈ 0.3, but disfavoring interpretations with Q Na = 0.5. The same techniques indicate that CDMS-Ge should see an O(1) modulation, and XENON100 should have seen 10-30 events (based upon the modulation in the 1.5-3.1 keVee range), unless L eff is smaller than recent measurements.Models such as inelastic dark matter provide a good fit to the modulation, but not the spectrum. We note that tensions with XENON could be alleviated in such models if the peak is dominantly in April, when XENON data are not available due to noise.

“…The NMSSM can also accommodate low-mass neutralino DM [77][78][79][80][81][82][83]. Several studies have recently pointed out that these neutralinos can also explain the GCE [53][54][55] when they are either singlino-Higgsino or bino-Higgsino admixtures [53].…”

We show that the right-handed (RH) sneutrino in the next-to-minimal supersymmetric standard model can account for the observed excess in the Fermi-LAT spectrum of gamma rays from the Galactic center, while fulfilling all the current experimental constraints from the LHC as well as from direct and indirect dark matter searches. We have explored the parameter space of this scenario, computed the gamma-ray spectrum for each phenomenologically viable solution and then performed a χ 2 fit to the excess. Unlike previous studies based on model-independent interpretations, we have taken into account the full annihilation spectrum, without assuming pure annihilation channels. Furthermore, we have incorporated limits from direct detection experiments, LHC bounds and also the constraints from Fermi-LAT on dwarf spheroidal galaxies and gamma-ray spectral lines. In addition, we have estimated the effect of the most recent Fermi-LAT reprocessed data (pass 8). In general, we obtain good fits to the Galactic center excess (GCE) when the RH sneutrino annihilates mainly into pairs of light singletlike scalar or pseudoscalar Higgs bosons that subsequently decay in flight, producing four-body final states and spectral features that improve the goodness of the fit at large energies. The best fit (χ 2 ¼ 20.8) corresponds to a RH sneutrino with a mass of 64 GeV which annihilates preferentially into a pair of light singletlike pseudoscalar Higgs bosons (with masses of order 60 GeV). Besides, we have analyzed other channels that also provide good fits to the excess. Finally, we discuss the implications for direct and indirect detection searches paying special attention to the possible appearanc...

“…We need to find ways to detect it directly and a number of very sophisticated searches are underway [3][4][5], with at times confusing results [6,7]. To guide those searches we need theoretical models for what the dark matter might be and what cross section one might expect it to have for scattering from hadronic matter.…”
