+//      File name:     G4ChargedUnknownParticle.cc
+//
+//      Author:        A.Ribon
+// 
+//      Creation date: August 2024
+//
+//      Description:   This class is similar to G4UnknownParticle,
+//                     i.e. representing particles with valid PDG code but
+//                     unknown to Geant4 - e.g. produced by MC event
+//                     generators - but with the extra requirement of having
+//                     a non-zero electric charge.
+//                     While for G4UnknownParticle is possible to assign
+//                     transportation and decay processes, for
+//                     G4ChargedUnknownParticle is also possible to assign
+//                     ionisation and multiple scattering.
+//
