Hello again,
Another question about beam smearing.
When I apply a beam smear of a reaction, does pluto preserve the production cross section for that specific beam energy?
I have investigated the output of the code below, and it seems the answer is no. So I ask the forum in case I am coding incorrectly.
double ebeam_min = 1.1725;
double ebeam_max = 5.44575;
PBeamSmearing *beam_smear = new PBeamSmearing("beam_smear", "Beam smearing");
TF1* beam_smear_fn = new TF1("beam_smear_fn", "1./x", ebeam_min, ebeam_max);
beam_smear->SetReaction("g + p");
beam_smear->SetMomentumFunction(beam_smear_fn);
makeDistributionManager()->Add(beam_smear);
((PDalitzDecay * )makeDistributionManager()->GetDistribution("eta_dalitz"))->SetUseQED(1);
PReaction my_reaction("_P1 = 2.2","g","p","p eta [dilepton [e+ e-] g]",creater,1,0,0,0);
Thanks
Michael
