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, Eugene, … )
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, including Λ(1520) (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 (Matt, Adam, Vincent, ...)
Study π⁰π⁰ spectrum as a function of t, E_γ, contributions from S and D waves (Annika, Alex, ...)
