About papas, heppy et cetra
Particle propagation is done by geometry calculation. To valid the calculation several different cases were plotted.

Output tree
The output tree contains branches which can be divided in several groups:
- reconstructed particle parameters;
- generated particle parameters;
- generated vertices;
- connection between reconstructed particles, generated particles and generated vertices.
The table below presents branches and description of their content.
Name | Type | Length | Description |
---|---|---|---|
Reconstructed particles | |||
n | int | 1 | The number of reconstructed particles. |
px | float [] | n | The reconstructed particle momentum: x coordinate. |
py | float [] | n | The reconstructed particle momentum: y coordinate. |
pz | float [] | n | The reconstructed particle momentum: z coordinate. |
Generated particles | |||
n0 | int | 1 | The number of generated particles. |
px0 | float [] | n0 | The generated particle momentum: x coordinate. |
py0 | float [] | n0 | The generated particle momentum: y coordinate. |
pz0 | float [] | n0 | The generated particle momentum: z coordinate. |
Generated vertices | |||
nv0 | int | 1 | The number of generated vertices. |
vx0 | float [] | nv0 | The generated vertex: x coordinate. |
vy0 | float [] | nv0 | The generated vertex: y coordinate. |
vz0 | float [] | nv0 | The generated vertex: z coordinate. |
