Sets center-of-mass energy sqrts(s) in GeV.

  • 2016/10/07 Daniel Rauch (danie.nosp@m.l.ra.nosp@m.uch@d.nosp@m.esy..nosp@m.de)

    The extrapolation of the intrinsic pT /Herwig/Shower/Evolver:IntrinsicPtGaussian depending on sqrt(s) according to the formula

    \[ p_{T, intrinsic}^{default} = 1.85 \text{GeV} + \sqrt{s}*(0.1/4000.0) \]

    was removed after discussion with the authors since the intrinsic pT is tuned and the extrapolated value disagreed with the tuned value.
