Evaluate a transfer function on Pt described by a Gaussian distribution. More...
Detailed Description
Evaluate a transfer function on Pt described by a Gaussian distribution.
This module takes as inputs two LorentzVectors: a 'gen-level' particle (which may be computed using for instance a Block or a 'real' transfer function) and a 'reco-level' particle (experimentally reconstructed). Assuming the LorentzVectors differ only by their Pt, this module returns the value of a transfer function (TF) evaluated on their respective Pt.
The TF is a Gaussian distribution that describes the difference between the reconstructed and the generated Pt ( \(P_{T_{rec}}-P_{T_{gen}}\)). The width of the distribution, parametrised as a fraction of \(P_{T_{gen}}\), is set as parameter.
Integration dimension
This module requires 0 phase-space points.
Parameters
| Name | Type | Description |
|---|---|---|
sigma | double | Fraction of the Pt yielding the width of the Gaussian distribution (with sigma at 0.1, \(\sigma_{gauss} = 0.1 \cdot P_{T_{gen}}\)). |
Inputs
| Name | Type | Description |
|---|---|---|
reco_particle | LorentzVector | Experimentally reconstructed particle. |
gen_particle | LorentzVector | Gen-level particle. |
Outputs
| Name | Type | Description |
|---|---|---|
TF | double | Value of the TF evaluated on the reco and gen Pt. |

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.
