5 TeV pgun collisions, Single particles type, PARTICLE GUN generator: pgun_pi_single_mu40

Single particle gun for detector studies: A particle gun with single pions. One pion per event. Production at (x,y,z,t)=(0,0,0,0). Pi+ and Pi- are alternated. Momentum of pions is 0.5, 5, 50, 500, 5000 GeV (alternated). Particles are generated using a uniform distribution in Phi and uniform distribution in Eta (pseudorapidity) in the range [-4.5,4.5]. Mixing with pileup: Each event is mixed with pileup using the tool described in arXiv:1510.06638. The pileup events use ATLAS A2 tune (all inelastic, including single and double diffractive events). The CM energy was 14 TeV. Events were generated with PYTHIA8. Events are mixed using a Poisson distribution with the mean mu=40 (average number of MinBias events). Then, only pileup particles around the single pion where taken in the cone 0.1 defined in eta and phi.
