Message-ID: <Pine.SGI.4.31.0112041045420.2519625-100000@fsgi01.fnal.gov> Hi Adam, I don't know why you are making this so complicated? We do not need to review the NuTeV analysis to make a real contribution. I'm suggesting we take advantage of having the world's experts on nuclear effects in neutrino interactions, gathered in one place, to address a question of nuclear effects in neutrino interactions! I also believe that there is a difference in the nuclear effects between NC and CC and I'd like to take advantage of the assembled expertise to see if we might better understand the physics and, perhaps, the size of the difference. Sharing this accumulated wisdom with NuTeV for inclusion in their analysis (if, as I suspect, they have not considered detailed nuclear corrections) or comparison with what they have done can only help the community understand their result. This is just another opinion... Jorge On Tue, 4 Dec 2001, Adam Para wrote: > Jorge, > this is an internal matter of NuTeV.
