TL;DR
This paper reports measurements of rho^0 meson production in proton-proton collisions at 3.67 GeV/c, revealing a lower cross section than expected and a strong angular anisotropy in the production process.
Contribution
First measurement of rho^0 meson production cross sections and angular distributions at this energy in pp collisions.
Findings
Total cross section: 23.4 ± 0.8 ± 8 μb
Strong anisotropy in differential cross sections
Lower cross section than in heavy ion collision models
Abstract
Total and differential cross sections for the exclusive reaction pp->pp rho^0 observed via the pi+pi- decay channel have been measured at beam momentum=3.67 GeV/c. The observed total meson production cross section is determined to be 23.4 +- 0.8 +-8 microb 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 cos^2(theta^{CM}) in the rho^0 meson production.
