A Study of High Transverse Momentum Eta Meson Production
- Univ. of Rochester, NY (United States)
Production of high transverse momentum ($$P_T$$) $$\eta$$ (eta) mesons by hadron beams with incident momentum of 530 GeV/c ($$\sqrt{s}$$ = 31.6 GeV) has been measured using the E706 spectrometer at FNAL. The $$\gamma\gamma$$ decay mode was studied using data from the highly segmented liquid argon calorimeter in E706. Results are presented for inclusive $$\eta$$ production for $$\pi^-$$ and $$p$$ beams on a beryllium target, and compared to inclusive $$\pi^0$$ production. Data cover the range of transverse momentum of 3.5 < $$P_T$$ < 10 GeV /c and rapidity $$\mid y \mid$$ < 0.7. The integrated ratio of inclusive $$\eta$$ production for incident $K^-$ and $$\pi^-$$ at 530 GeV/c ($$K^- Be \to \eta X/\pi^- Be \to \eta X$$) was found to be 1.32 ± 0.32 measured for the range 3.5 < 6.0 Ge V/c with rapidity $$\mid y \mid$$ < 1.0.
