3 | Makes integration of d(sig)/dxdQ2 (DIS) for neutrino/antineutrino over x and then over Q2, |
---|
4 | having as an intermediate result the d(sig)/dQ2 distribution and as a final result sig_tot. |
---|
5 | Separation of QES (W<M_N+m_pi) is planned at this time. |
---|
6 | Output for 20 points equidistant from ln(E_min) to ln(E_max=300 (GeV)) (A=12): |

60 | Conclusion (05.10.2005): |
---|
61 | a) at high energies sig(nu) and sig(anu) look to be close to the experimental values |
---|
62 | b) fL OFF increase less then by 10% -> the only hope is to modify C(Q2), which is bigger |
---|
63 | c) both waysof calculation give the same result (within the accuracy of calculation)(?) |
