3 Motivation The interpretation of neutrino experiments requires good control of nuclear physics From (e, e ) we know that nuclear effects can be large Can we extract predictions for ν-a in the QEP and regions from e-a experimental cross sections? General strategy [1.] Extract scaling function from (e, e ) data, embodying the nuclear physics content of the problem [2.] Invert the scaling approach to predict (ν l, l) cross sections in the few-gev region Maria B.

26 A transverse scaling function can be constructed where no LT separation is available. Assumption: f L is universal. Then 1. Σ L = 1 k F f L σ M v L G L, 2. Σ T = d2 σ dω e dω Σ L 3. f T (ψ ) = Σ T σ M v T G T Maieron, Donnelly & Sick, Phys.Rev.C 65, (2002)

29 the longitudinal part of the cross section superscales the transverse part does not : reasonably good scaling of the second kind, but something is breaking the scaling of the first kind, especially above the QE peak: inelastic scattering from the nucleons MEC and their associated correlations (required by gauge invariance) in both 1p-1h and 2p-2h channels initial and final state interaction effects

31 Fit of QE Superscaling Function

32 Scaling in the region The scaling analysis performed in the QEP can be extended to the -resonance peak To isolate the contributions in the region, we use the following procedure: [ ] d 1. 2 σ dω e = 1 dω k QE F f QE (ψ QE )σ M(v L G L + v T G T ) [ ] [ ] [ ] 2. = d 2 σ dω e dω d 2 σ dω e dω tot 3. superscaling function d 2 σ dω e dω QE

33 f (q, ψ ) k F [d 2 σ/dω e dω] σ M[v L G L +v T G T ] Dividing factors G L = κ 2τ [ N {( 1 + τρ 2 ) w 2 (τ) w 1 (τ) }] + O(η 2 F ) G T = 1 κ [ N { w 1 (τ) }] + O(η 2 F )

34 N single-baryon responses: w 1 (τ) = ν 1 w 2 (τ) = ν 2 [ G 2 M, (τ) + 3G 2 E, [ (τ)] G 2 M, (τ) + 3G 2 E, (τ) + 4τ ] G 2 µ C, (τ) 2 Electric, magnetic and Coulomb N form factors G M, (τ) = 2.97g (Q 2 ) G E, (τ) = 0.03g (Q 2 ) G C, (τ) = 0.15G M, (τ) g (Q 2 ) G Ep(τ) 1 + τ ; G Ep (τ) = 1 [ τ] 2

35 By doing this subtraction, we remove the impulsive L and T contributions that arise from elastic en scattering, leaving (at least) MEC effects with their associated correlations ( 10-20%) impulsive contributions arising from inelastic en scattering This approach can work only at ψ < 0, since at ψ > 0 other resonances and the tail of DIS start contributing Plot f vs ψ

48 Comparison of superscaling with RFG

49 Results Dramatic difference between ν and ν at backward angles, since X T X T (constructive interference in ν scattering, cancellation in ν): small changes in the model could have large effects on the predictions for ν In the ν case the T and T responses dominate (CC, CL, LL < 5%) in both QEand regions The QE and contributions are comparable for θ 90 o RFG (and mean field) predictions differ significantly from the scaling predictions Maria B. Barbaro NUFACT05, Frascati, June 21-26, 2005 Page 49

50 Conclusions (e, e ) Scaling is observed in inclusive electron scattering for high energies (several hundred MeV to a few GeV) from the scaling region up to the peak. For the longitudinal contribution it is possible to find a scaling function f QE which, when plotted versus ψ QE, is seen to superscale. This universal scaling function embodies the basic nuclear dynamics in the problem. The scaling function f QE is used to obtain the impulsive part of the transverse response Maria B. Barbaro NUFACT05, Frascati, June 21-26, 2005 Page 50

51 The residual is analyzed in terms of a scaling function f by dividing by the elementary N cross section and plotted versus a scaling variable ψ Very good representation of inclusive electron scattering at relatively high energies up to the peak. (ν, l) Invert the scaling procedure: use the empirical scaling functions and the N N and N weak amplitudes to predict charge-changing νa and νa cross sections for the same range of kinematics.

52 Future work (in progress): 1. extend the scaling approach to neutral current neutrino and antineutrino scattering 2. microscopic model: role of MEC and associated correlations in ph and 2p2h channels 3. explaining the specific nature of the scaling functions (in particular the asymmetric shape) Maria B.
