* This cut discards all the events whose rigidity modulus and dE/dX (both given by TRK) are outside a pre-defined band (by Nico De Simone). |
| 19 |
|
|
* Here rigidity is defined as p/Z (GV) where Z is the particle charge (WITH SIGN) and p the momentum modulus: therefore rigidity can be positive or negative. |
