Updated bounds on milli-charged particles
Sacha Davidson1, Steen Hannestad2 and Georg Raffelt3
Show affiliationsWe update the bounds on fermions with electric charge 
e and mass m. For m 
me we find 10−15 < 1 is excluded by laboratory experiments, astrophysics and cosmology. For larger masses, the limits are less restrictive and depend on m. For milli-charged neutrinos, the limits are stronger, especially if the different flavors mix as suggested by current experimental evidence.
