// Implementation of a stable particle class for use in general analyses in CMS. The contents of a
|
| 7 |
|
|
// stable particle is basically its link to the track it refers to. This will be hopefully at some
|
| 8 |
|
|
// point a useful and good implementation. See the double dispatcher doAction(MyAction).
