Build the initial partons given the whole final state. More...
Detailed Description
Build the initial partons given the whole final state.
Define the initial partons 4-momenta given the particles present in the final state.
If the parameter do_transverse_boost
is set to true
, the partons are boosted in the transverse direction to satisfy energy-momentum conservation. Otherwise, the partons are simply built using the total energy and longitudinal momentum, without enforcing conservation of transverse momentum.
Use of the transverse boost or not can depend on how the invisibles are reconstructed by the blocks: if the block already enforces momentum conservation, applying the boost or not will yield the same result.
Integration dimension
This module requires 0 phase-space point.

Main function.
This method is called for each integration step. The module's logic and work happen here.
You'll usually want to override this function if you want your module to perform some task.
