◆ AvgProb() [1/2]

double PMNS_Base::AvgProb	(	int	flvi,
		int	flvf,
		double	E,
		double	dE = `0`
	)

virtual

Compute the average probability of flvi going to flvf over a bin of energy E with width dE.

This gets transformed into L/E, since the oscillation terms have arguments linear in L/E and not E.

This function works best for single paths. In multiple paths the accuracy may be somewhat worse. If needed, average over smaller energy ranges.

Flavours are:

  0 = nue, 1 = numu, 2 = nutau
  3 = sterile_1, 4 = sterile_2, etc.

Parameters

flvi	- The neutrino starting flavour.
flvf	- The neutrino final flavour.
E	- The neutrino energy in the bin center in GeV
dE	- The energy bin width in GeV

Returns: Average neutrino oscillation probability

double PMNS_Base::AvgProbLoE	(	int	flvi,
		int	flvf,

	)

virtual

Compute the average probability of flvi going to flvf over a bin of L/E with width dLoE.

The probabilities are weighted by (L/E)^-2 so that event density is flat in energy. This avoids giving too much weight to low energies. Better approximations would be achieved if we used an interpolated event density.

This function works best for single paths. In multiple paths the accuracy may be somewhat worse. If needed, average over smaller L/E ranges.

Flavours are:

  0 = nue, 1 = numu, 2 = nutau
  3 = sterile_1, 4 = sterile_2, etc.

Parameters

flvi	- The neutrino starting flavour.
flvf	- The neutrino final flavour.
LoE	- The neutrino L/E value in the bin center in km/GeV
dLoE	- The L/E bin width in km/GeV

◆ BuildHms()

void PMNS_Base::BuildHms ( )

protectedvirtual

Build Hms = H*2E, where H is the Hamiltonian in vacuum on flavour basis and E is the neutrino energy in eV. Hms is effectively the matrix of masses squared.

This is a hermitian matrix, so only the upper triangular part needs to be filled

The construction of the Hamiltonian avoids computing terms that are simply zero. This has a big impact in the computation time.

Reimplemented in OscProb::PMNS_Decay, and OscProb::PMNS_SNSI.
