Interpolation

The main idea is to use information from other experiments: ISR, CDF and CMS at 7.00 TeV.

Note

goal of the project: exploit the high statistics 7 (and 8) TeV datasets as reference for HI studies (eg ), to complement the limited-statistics 2.76 TeV pp dataset

strategy: perform interpolations of cross-section values versus sqrt(s), using heuristic parameterizations the parameterization used is with A and T free parameters in the fit.

alternative/complementary ideas: use pythia MC generated at different energies? use simplified models such as CEM (by Ramona et al)

Fitting the three datasets at the three different energies yields
