Member Function Documentation

angularDistribution()

DistributionSampler OMSimENES::angularDistribution ( G4double  p_energy )

privatevirtual

This function calculates the angular distribution for electrons scattered by neutrinos. The foundation for this computation is taken from the reference: "Carlo Giunti and Chung W.Kim (2007), Fundamentals of Neutrino Physics and Astrophysics, Oxford University Press, Chapter 5, eq. 5.29".

Parameters

p_energy

The energy of the incident neutrino.

Implements SNBaseParticleGenerator.

calculateSecondaryParticleEnergy()

G4double OMSimENES::calculateSecondaryParticleEnergy ( G4double  p_NuEnergy, G4double  p_cosTheta  )

privatevirtual

The computation utilizes the formula for the energy of the electron as a function of incident neutrino energy and the scatter angle, based on the formula provided in the reference: "Carlo Giunti and Chung W.Kim (2007), Fundamentals of Neutrino Physics and Astrophysics, Oxford University Press, Chapter 5, eq. 5.27".

Parameters

p_NuEnergy	The energy of the incident neutrino.
p_cosTheta	The cosine of the scattering angle.

Returns

Calculated energy value of the electron post scattering.

Implements SNBaseParticleGenerator.

initialiseParticle()

void OMSimENES::initialiseParticle ( )

privatevirtual

Implements SNBaseParticleGenerator.

totalCrossSection()

G4double OMSimENES::totalCrossSection ( G4double  p_energy )

privatevirtual

This function determines the total cross-section for the scattering of neutrinos with electrons given a specific incident neutrino energy. The computational foundation is derived from: "M. Buchkremer, Electroweak Interactions: Neutral currents in neutrino-lepton elastic scattering experiments, Université Catholique de Louvain /CP3, 2011."

Parameters

p_energy

The energy of the incident neutrino.

Returns

Calculated total cross-section value for the given energy.

Implements SNBaseParticleGenerator.
