“…If the DM is made of the so-called Weakly Interacting Massive Particles (WIMPs) DM [17,18], these small subhalos may outshine in gamma rays. WIMPs can achieve the correct relic DM abundance (the so-called "WIMP miracle"), through self-annihilation in the early Universe.…”

The ΛCDM cosmological framework predicts the existence of thousands of subhalos in our own Galaxy not massive enough to retain baryons and become visible. Yet, some of them may outshine in gamma rays provided that the dark matter is made of weakly interacting massive particles (WIMPs), that would self-annihilate and would appear as unidentified gamma-ray sources (unIDs) in gamma-ray catalogs. Indeed, unIDs have proven to be competitive targets for dark matter searches with gamma rays. In this work, we focus on the three high-latitude (|b| ≥ 10 o ) sources present in the 2HWC catalog of the High Altitude Water Cherenkov (HAWC) observatory with no clear associations at other wavelenghts. Indeed, only one of these sources, 2HWC J1040+308, is found to be above the HAWC detection threshold when considering 760 days of data, i.e., a factor 1.5 more exposure time than in the original 2HWC catalog. Other gamma-ray instruments such as Fermi-LAT or VERITAS at lower energies do not detect the source. Also, this unID is reported as spatially extended, making it even more interesting in a dark matter search context. While waiting for more data that may shed further light on the nature of this source, we set competitive upper limits on the annihilation cross section by comparing this HAWC unID to expectations based on state-of-the-art N-body cosmological simulations of the Galactic subhalo population. We find these constraints to be particularly competitive for heavy WIMPs, i.e., masses above ∼ 25 (40) TeV in the case of the bb (τ + τ − ) annihilation channel, reaching velocity-averaged cross section values of 2 · 10 −25 (5 · 10 −25 ) cm 3 s −1 . Although far from testing the thermal relic cross section value, the obtained limits are independent and nicely complementary to those from radically different DM analyses and targets, demonstrating once again the high potential of this DM search approach.

“…The negative searches [42][43][44] so far have added one more feature: The DM must have exceedingly suppressed interactions with the SM matter. It is not hard to see that the spin-3/2 fermion ψ μ possesses all these properties.…”

Here we show that a massive spin-3/2 field can hide in the SM spectrum in a way revealing itself only virtually. We study collider signatures and loop effects of this field, and determine its role in Higgs inflation and its potential as dark matter. We show that this spin-3/2 field has a rich linear collider phenomenology and motivates consideration of a neutrino-Higgs collider. We also show that the study of Higgs inflation, dark matter and dark energy can reveal more about the neutrino and dark sector.

“…Due to their accidental relationship with the electroweak scale, DM candidates known as weakly interacting massive particles (WIMPs) [3] have received most of the attention. Negative results from direct and indirect searches [4,5] of these WIMPs especially in the electroweak (EW) mass scale range suggest that more attention should be paid to less explored avenues such as the multi-TeV WIMP realizations.…”

The impact of electroweak Sudakov logarithms on the endpoint of the photon spectrum for wino dark matter annihilation was studied intensively over the last several years. In this work, we extend these results to Higgsino dark matter χ 0 1 . We achieve NLL' resummation accuracy for narrow and intermediate spectral energy resolutions, of order m 2 W /m χ and m W , respectively. This is the most accurate prediction to date for the yield of high-energy γ-rays from χ 0 1 χ 0 1 → γ + X annihilation for the energy resolutions realized by current and next-generation telescopes. We also discuss for the first time the effect of power corrections in m W /m χ in this context and argue why they are not sizeable.
