Workshop 5 – Cross Section, Nuclear Data, and Uncertainties

Statistical treatment of detection cross-section uncertainties in the analysis of solar neutrino data

We propose a modification to the standard statistical treatment of the detection cross-section uncertainties in the analysis of solar neutrino data. We argue that the uncertainties of the energy-averaged cross sections of the different neutrino fluxes in the same experiment should be treated as correlated. We show that the resulting allowed regions for the neutrino oscillation parameters are si...

On the theoretical and experimental uncertainties in the extraction of the J/ absorption cross section in cold nuclear matter

We investigate the cold nuclear matter effects on J/ψ production, whose understanding is fundamental to study the quark-gluon plasma. Two of these effects are of particular relevance: the shadowing of the parton distributions and the nuclear absorption of the cc̄ pair. If J/ψ’s are not produced via a 2→ 1 process as suggested by recent theoretical works, one has to modify accordingly the way to ...

Extracting the dipole cross-section from photo- and electro-production total cross-section data

We report on a successful attempt to extract the cross-section for the high-energy scattering of colour dipoles of fixed transverse size off protons using electroproduction and photoproduction total crosssection data, subject to the constraint provided by the ratio of the overall photon dissociation cross-section to the total cross-section. 13.60.Hb, 25.20.Lj, 25.30.Rw, 13.38.-t, 24.85.+p, 12.4...

Nonlinear Regression On Cross-Section Data

Investigation of activation cross-section data of proton induced nuclear reactions on rhenium.

In the frame of systematic investigations of activation cross-section data for different applications the excitation functions of (nat)Re(p,x)(185)Os, (183m)Os, (183g)Os, (182)Os, (181m)Os, (186g)Re, (184m)Re, (184g)Re, (183)Re, (182m)Re, (182g)Re and (181g)Re reactions were measured up to 70MeV. The data for the (nat)Re(p,x) (183m)Os, (183g)Os, (182)Os, (181g)Os,(186g)Re, (184m)Re,(182m)Re, (1...
