Spring 2015 Reactions/Hadrons Observation Status

This table summarizes the status of reactions and hadrons that have been seen.

Last Updated -- 27 Feb. 2015

Reactions and Hadrons:

    • red - Not seen yet
    • yellow - Seen, but not with 5 σ significance
    • green - Seen with >5 σ significance

(5 σ is rather arbitrary, we should quantify when possible)

Non-strange Reactions

Reaction Status Notes Predicted cross sections
p\pi ^{+}\pi ^{-} See Justin's studies 13.5 ± 0.5 μb
p\omega See Justin's studies. ω → π+ π- π0 1.9 ± 0.3 μb
p\pi ^{+}\pi ^{-}\pi ^{0} See Justin's studies no data
p\eta Should be seen in η → 2 γ, η → π+ π- π0 no data
\pi ^{+}\pi ^{+}\pi ^{-}n XXX μb
