Correct length units in Pythia interface?
Reading through the Pythia interaction interface I found this snippet:
const double sigEla = fSigma.sigmaEl(); const double sigProd = fSigma.sigmaTot() - sigEla; return std::make_tuple(sigProd * 1_mb, sigEla * 1_mb);
I know that Pythia uses femtometer as internal base unit for lengths, therefore cross-sections are in fm², which is one order of magnitude different from a mb. I have the suspicion that the
1_mb is not correct.
