“…Above a few GeV, the astrophysical background of positrons is not under control as for antiprotons. As a matter of fact, the positron excess reported by AMS-02 [56] could be explained by the presence of young and nearby pulsars. In addition, the lack of knowledge about these systems makes it difficult to distinguish this hypothesis from an exotic component to explain the data.…”

Abstract:We study the implications of dark matter searches, together with collider constraints, on the phenomenological MSSM with neutralino dark matter and focus on the consequences of the related uncertainties in some detail. We consider, inter alia, the latest results from AMS-02, Fermi-LAT and XENON1T. In particular, we examine the impact of the choice of the dark matter halo profile, as well as the propagation model for cosmic rays, for dark matter indirect detection and show that the constraints on the MSSM differ by one to two orders of magnitude depending on the astrophysical hypotheses. On the other hand, our limited knowledge of the local relic density in the vicinity of the Earth and the velocity of Earth in the dark matter halo leads to a factor 3 in the exclusion limits obtained by direct detection experiments. We identified the astrophysical models leading to the most conservative and the most stringent constraints and for each case studied the complementarities with the latest LHC measurements and limits from Higgs, SUSY and monojet searches. We show that combining all data from dark matter searches and colliders, a large fraction of our supersymmetric sample could be probed. Whereas the direct detection constraints are rather robust under the astrophysical assumptions, the uncertainties related to indirect detection can have an important impact on the number of the excluded points.

“…The lack of evidence for weakly interacting massive particles (WIMPs) in direct detection (DD) experiments [30][31][32][33], increasingly strong constraints on thermal WIMPs from indirect detection (ID) experiments [34][35][36][37][38], and non-observation of beyond the Standard Model (BSM) missing transverse energy signatures at the LHC [39,40], combine to an increasing unease with the standard WIMP miracle paradigm. On the other hand, dark matter coupled to kinetically mixed hidden photons suffers from strong direct detection constraints (see, e.g., [41]).…”

A tale of two portals: testing light, hidden new physics at future e + e − colliders

We investigate the prospects for producing new, light, hidden states at a future e + e − collider in a Higgsed dark U(1) D model, which we call the Double Dark Portal model. The simultaneous presence of both vector and scalar portal couplings immediately modifies the Standard Model Higgsstrahlung channel, e + e − → Zh, at leading order in each coupling. In addition, each portal leads to complementary signals which can be probed at direct and indirect detection dark matter experiments. After accounting for current constraints from LEP and LHC, we demonstrate that a future e + e − Higgs factory will have unique and leading sensitivity to the two portal couplings by studying a host of new production, decay, and radiative return processes. Besides the possibility of exotic Higgs decays, we highlight the importance of direct dark vector and dark scalar production at e + e − machines, whose invisible decays can be tagged from the recoil mass method.

“…It has been gathering data since May 2011 detecting and identifying cosmic-ray electrons, positrons, protons, anti-protons, heavy nuclei up to Zinc (Z=30) and photons. Recently, first results on the measurement of the cosmic-ray positron fraction and on the absolute fluxes of electrons and positrons have been published [1][2][3][4] and will be reviewed in this presentation. The positron fraction has been measured with unprecedented accuracy up to 500 GeV and emphasizes the need of a primary source of positrons to explain the rise of the positron fraction at high energies.…”

Abstract. AMS02 experiment has collected data on Cosmic Rays for three years on the International Space Station, since its installation on May, 19 2011. The fluxes of electrons, positrons and protons, together with the results on Boron and Carbon ratio, will be discussed, as well as their implication in terms of Cosmic Ray propagation and in terms of limits on the existence of Dark Matter in the electroweak energy range.
