Production of four-prong final states in photon-photon collisions
Abstract
Results are presented on the exclusive production of four-prong final states in photon-photon collisions from the TPC/Two-Gamma detector at the SLAC e+e- storage ring PEP. Measurement of dE/dx and momentum in the time-projection chamber (TPC) provides identification of the final states 2π+2π-, K+K-π+π-, and 2K+2K-. For two quasireal incident photons, both the 2π+2π- and K+K-π+π- cross sections show a steep rise from threshold to a peak value, …
