Action Items
- Make prediction, based on the global Regge analysis for γ p -> K+Λ/Σ (also u-channel), γ p -> f2 p, γ p -> a2 p (Vincent, Ken, Andrea, Derek,…)
- Extend the moment analysis of two pseudoscalar meson photoproduction to electroproduction (clarify the role of beam helicity asymmetry) (Vincent,…)
- Adopt the Dalitz formalism (Misha’s paper) to γ p-> π π N (Misha, Adam, Victor, Eugine, … )
- Double Regge for η-π0 and η-π- (Δ++) (Colin, Lukasz, Alex, Matt, …)
- Use the recently measured spin density elements to constrain the model for diffractive vector meson photoproduction (Vincent, Alex, … )
- Revisit ω -> γ* π0, φ -> γ* π0 η’ -> ω γ* … transition from factors (Gluex is collecting data) (Igor, Miguel,)
- Single Regge (+ Deck) model for ππ, πη (Lukasz, …)
- Explore a theoretical mechanism to check consistency between COMPASS and CLAS results regarding ρπ coupling of the π1
- Study π0π0 spectrum as a function of t, Eγ, contributions from S and D waves (Annika, Alex, ...)
