| 英文摘要 | The reactions gamma gamma -> pi(+)pi(-)pi(+)pi(-) and gamma gamma -> pi(+)pi(0)pi(-)pi(0) are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161 GeV to 209 GeV with a total integrated luminosity of 698 pb(-1). A spin-parity-helicity analysis of the rho(0)rho(0) and p(+)p(-) systems for two-photon centre-of-mass energies between 1 and 3 GeV shows the dominance of the spin-parity state 2(+) with helicity 2. The contribution of 0(+) and 0(-) spin-parity states is also observed, whereas contributions of 2(-) states and of a state with spin-parity 2(+) and zero helicity are found to be negligible.
