Faster-than-light particles: A reply to Franklin

  • J. C. Cooper


Franklin's underrating the importance of the time-of-flight measurements contradicts Segrè's account of the experiment in two journals and Chamberlain's Nobel Prize acceptance speech. Franklin further fails to understand that Segrè's velocity selector method of determining antiproton and proton mass also depends upon measuring the S1-to-S2 flight distance. Franklin's conclusion that there is no evidence that the Segrè mesons are traveling faster than light is based on a faulty premise about the average antiproton velocity.
