[Clas_hadron] MENU talk

[Maurizio Ungaro]

Hi Paul,

thanks so much for your comments.

1. If you show it on full screen, those are animations, it won't show up over-layed.
2. and 3.  Lattice Group at Jefferson Lab, Carnegie Mellon University, Univ. of Maryland, and Trinity College (Dublin) are part of the Hadron Spectrum Collaboration.
They embarked on a program to compute the high lying excited state spectrum of baryons and mesons, as well as their (excited state) electromagnetic transition form-factors up to Q2 ∼ 10 GeV2. 
Page 3: these are S11 helicity amplitudes calculated from DA distribution (from lattice) using LCSR
Page 4: I will mention that on my talk. It's hard to fit on that slide.

Many of the slides are repetition, showing data at different Q2 for example, so they won't take time. In reality it's 20 "true" slides. I have 17+3 minutes.

The punchline I'll mention is that we'll have pi0 and eta cross sections that will provide valuable data to a. extract helicity amplitudes as a function of photon virtuality,  b. to be used in single, double meson combined analysis, c. to be used as beacon for non the non-perturbative method I mention in page 3. 

thanks,
mauri
