The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

Dark matter particles annihilating in the Galactic halo can provide a flux of positrons potentially observable in upcoming experiments, such as PAMELA and AMS-02. We discuss the spectral features which may be associated with dark matter annihilation in the positron spectrum and assess the prospects for observing such features in future experiments. Although we focus on some specific dark matter candidates, neutralinos and Kaluza-Klein states, we carry out our study in a model independent fashion. We also revisit the positron spectrum observed by HEAT.

The paper

Original abstract

Dark matter particles annihilating in the Galactic halo can provide a flux of positrons potentially observable in upcoming experiments, such as PAMELA and AMS-02. We discuss the spectral features which may be associated with dark matter annihilation in the positron spectrum and assess the prospects for observing such features in future experiments. Although we focus on some specific dark matter candidates, neutralinos and Kaluza-Klein states, we carry out our study in a model independent fashion. We also revisit the positron spectrum observed by HEAT.

Positrons from dark matter annihilation in the galactic halo: theoretical uncertainties
astro-ph 2007-12 conditional novelty 6.0 of 10

A new Bessel-expansion solution of the positron diffusion equation, combined with a scan over 1,600 boron-to-carbon-compatible propagation models, brackets the astrophysical uncertainty on the dark matter positron sig...
Global fits of the Non-Universal Higgs Model
hep-ph 2009-03 conditional novelty 5.0 of 10

Global fits of the Non-Universal Higgs Model show that higgsino-like dark matter near 1 TeV with spin-independent scattering of 10^-9 to 10^-8 pb is viable, disfavoured mainly by the muon g-2 constraint.
An Effective Theory of Dirac Dark Matter
hep-ph 2008-10 conditional novelty 5.0 of 10

A leptophilic Dirac fermion with a TeV-scale four-fermion operator reproduces the PAMELA positron excess with a small boost factor and has a natural supersymmetric realization as a Dirac bino.
High Energy Positrons and the WMAP Haze from Exciting Dark Matter
astro-ph 2008-02 conditional novelty 5.0 of 10

Exciting dark matter with a light mediator can fit the HEAT positron excess and the WMAP haze with a single free annihilation cross-section, and predicts a detectable positron signal at PAMELA if local dark matter den...
Direct, Indirect and Collider Detection of Neutralino Dark Matter In SUSY Models with Non-universal Higgs Masses
hep-ph 2005-04 conditional novelty 5.0 of 10

Allowing the GUT-scale Higgs soft masses to differ from the matter scalar mass opens neutralino annihilation funnels and higgsino regions at low tan beta and low m0, with observable direct, indirect and collider signals.

The PAMELA Positron Excess from Annihilations into a Light Boson
astro-ph 2008-10 conditional novelty 4.0 of 10

Dark matter annihilation into a sub-GeV boson that decays to leptons fits the PAMELA positron excess while kinematically avoiding any antiproton excess.
Annihilating dark matter and the galactic positron excess
astro-ph 2006-02 conditional novelty 4.0 of 10

Virtual Z boson decay from annihilating neutralinos can reproduce the low-energy galactic positron excess, but the high-energy spectrum requires mixing young free-streaming and older diffused positrons.

A comprehensive review of universal extra dimensions argues that the lightest Kaluza-Klein particle is a viable thermal dark matter candidate and lays out the collider, direct-detection, and indirect-detection signatu...
