#include <FlatRandomPtAndDxyGunProducer.h>
Generates single particle gun in HepMC format The d0 is taken by convention equal to dxy v1: first version of displaced Muon Gun flat in dxy(0, 50), flat in lz(-50, 50) v2: bugfixed, unit in HepMC is mm, rather than cm v3: check pz*vz>0, make sure muon is not flying back to beamspot, Lz is generated by Gauss distribution v4: dxy is produced with sign, (-500, 500) [mm] v5: check vx*px+vy*py>0, and muons inside beamline-symmetric cone is vetoed by lxy^2/c^2<=(vz-d) ^2 && vz-d>0
