Description
Running the example fails due to nan in s: Invoking Sherpa the following way: Examples/LHC_Pb_EPA $ ../../bin/Sherpa -f Run.dat -m Internal produces this output:
Single_Process::CalculateTotalXSec(): Calculate xs for '2_2PPpi+pi-' (Internal) Starting the calculation. Lean back and enjoy ... . Channel_Basics::SqLam argument nan <0 in Channel_Basics::sqlam() s;s1;s2: nan;0.0194798;0.0194798 Phase_Space_Handler::Check4Momentum(): {
p_0 = (nan,nan,nan,nan) (nan) p_1 = (nan,nan,nan,nan) (nan) p_2 = (nan,nan,nan,nan) (nan) p_3 = (nan,nan,nan,nan) (nan) p_in = (nan,nan,nan,nan) (nan) p_out = (nan,nan,nan,nan) (nan) diff = (nan,nan,nan,nan) (nan)
} ...
The behavior is quite similar for gamma gamma -> e+ e- using Comix
