More evidence in favour of Light Dark Matter particles?
arXiv:hep-ph/0408213 · doi:10.1103/PhysRevD.70.115013
Abstract
In a previous work, it was found that the Light Dark Matter (LDM) scenario could be a possible explanation to the 511 keV emission line detected at the centre of our galaxy. Here, we show that hints of this scenario may also have been discovered in particle physics experiments. This could explain the discrepancy between the measurement of the fine structure constant and the value written in the CODATA. Finally, our results indicate that some of the LDM features could be tested in accelerators. Their discovery might favour N=2 supersymmetry.
