*-*  Compute the closest distance of approach from point px,py to each segment
*-*  of a track.
*-*  The distance is computed in pixels units.

return particle name

 returns a pointer to the TParticlePDG object using the pdgcode
 if mode == 0 (default) always get a fresh value for the pointer.
 if mode != 0 this function returns directly the previously
              computed pointer from a previous call
 One can use mode=1 (faster) when the TParticle object is not part of a
 TClonesArray used in split mode in a Root TTree.
