Study of pi pi Implies K Anti K and pi pi Implies K Anti K* Scattering at 10 GeV/C

摘要

A study of the virtual reactions pi exp + pi exp - implies K exp + K exp - and pi exp + pi exp 0 implies K exp + K exp - pi exp + has been performed using the Large Aperture Solenoid Spectrometer (LASS) at the Stanford Linear Accelerator Center. A moment analysis of the K exp + K exp - and K exp + K exp - pi exp + systems is presented, yielding information on the leading natural spin-parity resonance states. The well-established states f(1270), f'(1515), and g(1700) are observed, and evidence is presented for a new state with J/sup P/ = 7 exp - in the K exp + K exp - pi exp + system at a mass of 2720 MeV.
