Measurement of the $\pi^0 \pi^0$ cross section in $\bar{p} p$ annihilations at $\sqrt(s)$ 3.0 GeV
Nuclear Physics(1992)
摘要
Abstract Data collected in the experiment R704 at the CERN ISR are used to study the annihilation process p p → π 0 π 0 at several centre-of-mass energies between 2.97 and 3.56 GeV. A total sample of 7359 events has been identified, from which cross sections and angular distributions in the interval 0 cos θ ∗ | have been measured.
