Particle Detector Development and Performance

The lifetime of the F± meson has been measured to be (3.5−1.8+2.4±0.9) × 10−13 s by means of the F±→φπ± decay mode. The measurement was made with the High Resolution Spectrometer at the SLAC e+e− storage ring PEP at a center-of-mass energy of 29 GeV.Received 3 January 1986DOI:https://doi.org/10.1103/PhysRevLett.56.1775©1986 American Physical Society
