  12. DON’T FORGET! WITH E-907 (MIPP) THIS UNCERTAINTY IN HADRON PRODUCTION SPECTRA WILL BE RESOLVED BY MEASURING THE SPECTRA OF HADRONS COMING OFF THE NUMI TARGET Neutrino Scattering in the NuMI Beam

  13. Obtaining the Latest NuMI Beam Simulations Neutrino Scattering in the NuMI Beam

  14. sTot, Fi(x,Q2),Duality and Nuclear Effects • Experiment: n (only) on nuclear targets: • ds/dxdQ off, mainly, carbon • Could say F2 = xF3 at high x, but … • Concentrate on careful measurement of transition region • Low energy (< 10 GeV) primarily from the 70’s and 80’s suffering from low statistics and large systematics (mainly from n flux measurements). • Mainly bubble chamber results --> larger correction for missing neutrals. D. Naples - NuInt02 Neutrino Scattering in the NuMI Beam

  15. How well do we model sTot ? S. Zeller - NuInt02 Neutrino Scattering in the NuMI Beam

  16. D. Naples Conclusions from NuInt02 Neutrino Scattering in the NuMI Beam

  17. Nuclear Effects • Without n can’t measure flavor dependence of nuclear effects • However, can make careful measurement of ratio of ds/dxdQoff C, Fe and Pb. Never measured before. Study shadowing and EMC effect with neutrinos! • Can measure dD(z)/dxdQoff C, Fe and Pb which would be a convolution of all nuclear effects including: boson (quark-flavor dependence) and transparency (final-state interactions / formation-length /color transparency)effects. • Behavior of F2 as x --> 1.0 in Nuclear Environment • Few-nucleon-correlation and multi-quark models allow quarks to have higher momentum ---> high x tail with F2e- ax • CCFR: a = 8.3 ± 0.7 ± 0.7, m/e: a = 16 ± 0.5 Neutrino Scattering in the NuMI Beam

  19. Add an n run • Experiment: nand n on nuclear targets: • Also measure ds/dxdQ off, mainly, C • Concentrate on careful measurement of transition region • In addition can extract all 6 structure functions individual PDF's in a given x,Q bin.

  20. Physics Results: High-xBj Parton Distribution Functions • The particular case of what is happening at high- xBj is currently a bit of controversial with indications that current global results not correct: • Drell-Yan production results ( E-866) may indicate that high-xBj (valence) quarksOVERESTIMATED. • A Jlab analysis of Jlab and SLAC high x DIS indicate high-xBj quarks UNDERESTIMATED. ≈ Statistical Errors for 1 year of he-n xBj CH LH2 LD2 .6 - .65 0.6% 2.2% 1.5% .65 - .7 0.7 2.6 1.7 .7 - .75 1.0 3.7 2.5 .75 - .8 1.3 5 3 .8 - .85 2 7 5 .85 - .9 3 11 7 .9 - 1.0 4 14 10 Measured / CTEQ6 Might be d/u ratio SLAC points CTEQ6 Neutrino Scattering in the NuMI Beam
