Phys. Rev. Lett. 89, 092001 (2002) [4 pages]ρ0 Meson Production in the pp→ppπ+π- Reaction at 3.67 GeV/cReceived 18 December 2001; published 12 August 2002 Total and differential cross sections for the exclusive reaction pp→ppρ observed via the π+π- decay channel have been measured at pbeam=3.67 GeV/c. The observed total meson production cross section is determined to be (23.4±0.8±8) μb and is significantly lower than typical cross sections used in model calculations for heavy-ion collisions. The differential cross sections measured indicate a strong anisotropy (∼cosθρCM) in the ρ0 meson production. © 2002 The American Physical Society URL:
