[Rgc_analysis] Trains

[Sebastian Kuhn]

Dear all,

I am still unhappy that our “SIDISDVCS” train has a cut W > 1.95 in it. This cut prevent us from studying ANY part of the resonance region (1 < W < 2) which, I am very sure, doesn’t contribute a lot of extra file size but is crucial if we want to study a wide variety of issues, including duality (exactly where do we have to cut at high x?), radiative corrections, and higher twist. We have a lot of papers on the various sum rules for different Q2, and RG-C can contribute significantly to the world data body on this; however, any such sum rules require to integrate over the entire region x < 1 including the resonance region.

So, unless I am missing something and the fully inclusive (e’ only) data for W < 2 are contained in some other train, I feel we are throwing away a wealth of additional information for what I expect to be a very modest reduction in file size. Hence, I urge us to drop the W < 1.95 cut.

Thanks - Sebastian
