“…Because scalar DM respects Bose-Einstein statistics and its annihilation is not p-wave suppressed, it is easier to find amenable regions of parameter space than for the neutralino, although direct-detection constraints are still strong. Fits to the spectrum of the GCE for annihilating sneutrino DM (including scalar annihilation channels) were examined more closely in [37]. Collider signatures of this scenario were discussed in [99].…”

“…More specifically, this signal can be well fit by [31][32][33][34][35][36][37][38][39][40] GeV dark matter particles annihilating to bb with a cross section of σv = (1.7 − 2.3) × 10 −26 cm 3 /s (or by somewhat lighter particles annihilating to lighter quarks with a slightly lower cross section) [1]. The possibility that this signal constitutes the first detection of particle dark matter interactions has received considerable interest, and many dark matter models have been put forth as potentially viable explanations for the observed excess .…”

“…Actually, a purely right-handed sneutrino either in a natural way, because of its very weak couplings with the rest of the matter implying a scattering cross section too small (supressed by Y ν ), and a relic density too large. However, now, through its direct coupling to the singlet in (4), the right-handed sneutrino can be not only a thermal relic DM, but also have a large enough scattering cross section with nuclei as to be detected (see [15] and [16,17], and references therein).…”
