"Tachyon" is a name which has been given to hypothetical particles which always travel faster than light. They can never travel slower than the speed of light.
I believe that there has been no "proof" of the existence of tachyons, although there has been a reported sighting in the 70's or 80's by someone studying cosmic rays that has never been reproduced, and there are some theories that tachyons are necessary to explain certain observable (or theoretically observable) conditions, which indirectly support their existence, but, AFAIK, nothing conclusive has yet been shown.
If you can find the article, please post a link.
