[Clas_hadron] Talk at IoP Nuclear Physics Conference (UK)

[Marco Ripani]

Hi Dave,
nice overview. A couple of comments:
- in your slide 10 (starting from zero) I would rather define the last 
energy region as "very high momentum transfer (pQCD)" instead of 
"perturbative QCD"
- is the cross section at the bottom-right corner of slide 13 
differential also in the variables of the Lambda decay products ? I have 
seen it in other presentations but I find it confusing as normally we 
think of dSigma/dOmega as just a two-body differential cross section; I 
think it is better to use the notation from the original paper of 
Barker, Donnachie and Storrow, 1975 (formula 13), where the spin density 
matrix of the recoiling baryon times the cross section is decomposed in 
its various pieces by using explicit Pauli matrices: in my opinion it is 
also easier to explain to a broader audience
- by having one or more explanatory slides like N. 13 with the above 
modifications, you may not need slide 12, which is not so immediate to 
grasp as opposed to slides like N. 13

Best wishes
Marco
