 The small mass splitting can cause problems in the automatic calculation of the decay width.
 One way to fix this problem is by replacing the argument of the square root of the return value of the function `calculate_apx_psarea` in the file `[MadGraph]/mg5decay/decay_objects.py` by its absolute value.
