Function Acts::computeEnergyLossRadiative

Function Documentation

float Acts::computeEnergyLossRadiative(const MaterialProperties &slab, int pdg, float m, float qOverP, float q = UnitConstants::e)

Compute the mean energy loss due to radiative effects at high energies.

This computes the mean energy loss -dE(x) using an approximative formula. Bremsstrahlung is always included; direct e+e- pair production and photo-nuclear interactions only for muons.

Parameters

  • slab: The traversed material and its properties

  • pdg: Particle type PDG identifier

  • m: Particle mass

  • qOverP: Particle charge divided by absolute momentum

  • q: Particle charge
