Configuration¶
Configuration files support JSON-like syntax and contain
general steering parameters for a run, FOAM parameters,
kinematic cuts and parameters of the Standard Model.
The configuration can be split into several files and included to index.conf
file by .include <relative or absolute path to file> macro.
Process parameters¶
pid [integer]¶
defines a process to calculate:
101: \(e^+e^- \to e^-e^+\),102: \(e^+e^- \to ZH\)103: \(e^+e^- \to \mu^-\mu^+\),104: \(e^+e^- \to \tau^-\tau^+\).
ecm [double]¶
sets collider energy in the center-of-momentum frame.
alr [integer]¶
switches generation mode:
0: \(\sigma\),1: \(\sigma_{RL}-\sigma_{LR}\),2: \(\sigma_{RL}+\sigma_{LR}\),3: \(\sigma_{0L}-\sigma_{0R}\),4: \(\sigma_{0L}+\sigma_{0R}\).
lamep [double]¶
polarization degree of the positron.
lamem [double]¶
polarization degree of the electron.
costhcut [double]¶
cut on \(|\cos\theta|\) for both final state particle.
ome [double]¶
is the parameter separating contributions from soft and hard photon Bremsstrahlung (\(\omega=ome \sqrt{s}/2\)).

iqed [integer]¶
0: disables QED corrections,1: with full QED corrections,2: only initial state QED radiation (ISR),3: initial-final QED radiation interference term (IFI),4: only final state QED radiation (FSR),5: sum of initial and final state radiation contributions [IFI+FSR],6: sum of initial state and initial-final QED interference terms [ISR+IFI].
iew [integer]¶
0: disables weak corrections,1: enables weak corrections.
iborn [integer]¶
0: enables NLO corrections,1: forces LO calculation.
ifgg [integer]¶
1: default vacuum polarization \((1+\mathcal{F}_{\gamma\gamma}(\mathrm{NLO}))\),2: ressummed vacuum polarization \((1/[1 - \mathcal{F}_{\gamma\gamma}(\mathrm{NLO})])\).
