Opposite-sign Pion Correlations

The main point people working on this for MDC3 are:
Randall Wells for inclusive HBT,
Dominik Flierl for Event-by-Event HBT,
and Zhangbu Xu for resonance reconstruction.

The main topics here are

• Further indication of source size from Coulomb correlations at low Qinv.
• Reconstruction of several meson resonances in Minv
  • rho⁰ ---> pi⁺ + pi^-       (~100% B.R.)
  • omega ---> pi⁺ + pi^- + pi⁰       (~89% B.R.)
    omega ---> pi⁺ + pi^-       (~2% B.R.)
  • eta ---> pi⁺ + pi^- + pi⁰       (~24% B.R.)
    eta ---> pi⁺ + pi^- + gamma       (~5% B.R.)

Here, is a pi-pi+ HBT study also using the (in)famous Quality cut, by Randy.
