Light weakly interacting massive particles

Abstract: Light weakly interacting massive particles (WIMPs) are dark matter particle candidates with weak scale interaction with the known particles, and mass in the GeV to tens of GeV range. Hints of light WIMPs have appeared in several dark matter searches in the last decade. The unprecedented possible coincidence into tantalizingly close regions of mass and cross section of four separate direct detection experimental hints and a potential indirect detection signal in gamma rays from the galactic center, aroused cons… Show more

“…In particular, the results of the KIMS-CsI experiment [176] disfavor interpretation of DAMA/LIBRA signal in which the DM particles scatter off iodine nuclei. This could be circumvented in specific scenarios, e.g., for Magnetic Inelastic DM (see, however, recent XENON1T limits [177]), in models with dominant WIMP inelastic spin-dependent coupling to protons if different quenching factors are assumed in both experiments [178,179] (for an extensive discussion see also [92]; for recent limits see [180]) or leptonically interacting DM particles that induce electron recoils [181] (see, however, Ref. [182] and references therein).…”

“…In spite of its experimental elusiveness, low-scale supersymmetry still (arguably) remains as the most complete and best motivated beyond the Standard Model (BSM) theory 1 . On top of solving the naturalness problem, supersymmetric theories with R parity conservation have naturally candidates for thermal Dark Matter (DM), the neutralinos.…”

“…On top of solving the naturalness problem, supersymmetric theories with R parity conservation have naturally candidates for thermal Dark Matter (DM), the neutralinos. A number of recent works [1][2][3][4][5][6] have pointed out that, out of the different neutralino spectra, a nearly pure Higgsino lightest supersymmetric particle (LSP) with a 1.1-1.2 TeV mass range remains as the most phenomenologically appealing candidate to DM 2 The attractiveness of this scenario relies on the fact that its capability to reproduce the observed value of Ωh 2 = 0.1186 ± 0.0020 [7] comes from the gauge interactions of the Higgsino multiplet alone and does not require a delicate mixture of different neutralino states (so-called 'well-tempering') [8].…”

“…Figura extraída de la referencia [13] La partículas que se producen a través del desacople o del freeze out, son llamadas reliquias térmicas, cuyos candidatos más populares son los WIMPs (weakly interactive massive particles), partículas masivas débilmente interactuantes. Para obtener la densidad reliquia adecuada a las observaciones, la sección eficaz de aniquilación debe ser del orden de éσvê Ä 3×10 −26 cm 3 s −1 , que es el orden de magnitud que se espera para una partícula de 100 GeV de masa que interactúa a través de la fuerza electrodébil [14].…”

“…Así mismo la producción de materia oscura se pudo dar por procesos no térmicos como el decaimiento de otras partículas con mayor masa o a través de ciertas condiciones de simetría [14]. Puede que las partículas de materia oscura nunca hayan experimentado el equilibrio térmico y haberse producido de forma no térmica después del período de inflación.…”
