Pi+ scattering cross section

From Tim:

Pi+ are really hard. The production spectrum overlaps strongly with Delta resonance scattering. But the nuclear cross sections are very different from those inferred from pi+pi and pi+n. Our detector may be destroying pi+ in a not terribly well-predicted way.

From Janet:

On question 17... a lot of people talk about using the hard scattering to identify pi+'s. What do we do about this? Who is working on a CCp+ or NCpi+ analysis?

Danny Devitt is working on the CCp+ interaction.
