Abstract

We propose a possible explanation for the recently observed anomalous 511 keV line with a new "millicharged" fermion. This new fermion is light [B(MeV)]. Nevertheless, it has never been observed by any collider experiments by virtue of its tiny electromagnetic charge ee. In particular, we constrain parameters of this millicharged particle if the 511 keV cosmic γ-ray emission from the galactic bulge is due to positron production from this new particle.
