Preoccupied with a paradigm

Some theorists are finding the recent results exciting with respect to the possibility of Dark Matter Particles of a particular energy self destructing.

This involves accepting some a priori assumptions that form the basis of the paradigm. The outlook is from the vantage point that the particles are sourced at a particular place and lose energy as they arrive to our detectors.

A couple recent arxiv submissions on the topic within the popular paradigm:

Decaying Hidden Gauge Boson and the PAMELA and ATIC/PPB-BETS Anomalies

Distinguishing Between Dark Matter and Pulsar Origins of the ATIC Electron Spectrum With Atmospheric Cherenkov Telescopes

Abstract: http://arxiv.org/abs/0811.3362

As and example of an alternative paradigm to arrive at the particular spike of energy range could be that the electrons are sourced from a variety of indefinite places, from nearby and far away pulsars for example and accepting that the distant electrons would still lose energy according to current theories, But then find a galactic accelerator that kicks them back up to the observed energy distribution. Different galaxies will have different peaks. Whether the acceleration is electromagnetic or gravitational, possibly due to the strength of the Dark Matter Effect within a galaxy, could be sorted out by comparing the masses of the effects between electrons, positrons, and protons. If it is blind to charge to mass ratios, this may implicate gravitational or gravity-like forces.
