Updated bounds on milli-charged particles

We update the bounds on fermions with electric charge epsilone and mass m(e psilon). For m(epsilon) less than or similar to m(e) we find 10(-15) less t han or similar to epsilon < 1 is excluded by laboratory experiments, astrop hysics and cosmology. For larger masses, the limits are less restrictive an d depend on m(<epsilon>). For milli-charged neutrinos, the limits are stron ger, especially if the different flavors mix as suggested by current experi mental evidence.
