Detailed Description

This class expands the PMNS_Fast class including a effects from decoherence in an increasing entropy and energy conserving model.

The model assumes a power law energy dependence of the decoherence parameters and that decoherence occurs in the effective mass basis.

◆ AvgProb() [1/2]

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

virtualinherited

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

Compute the average probability of nu_in 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:

Parameters

nu_in	- The neutrino initial state in flavour.
flvf	- The neutrino final flavour.

◆ AvgProbLoE() [1/2]

double PMNS_Base::AvgProbLoE	(	int	flvi,
		int	flvf,
		double	LoE,
		double	dLoE = `0`
	)

virtualinherited

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

Returns: Average neutrino oscillation probability

◆ AvgProbVectorLoE() [1/2]

vectorD PMNS_Base::AvgProbVectorLoE	(	int	flvi,
		double	LoE,
		double	dLoE = `0`
	)

virtualinherited

Compute the average probability of flvi going to all flavours 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.

Parameters

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

Returns: Average neutrino oscillation probabilities

◆ BuildHms()

void PMNS_Base::BuildHms ( )

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.

◆ SetStdPars()

void PMNS_Base::SetStdPars ( )

◆ SetStdPath()

void PMNS_Base::SetStdPath ( )

virtualinherited

Set standard single path.

Length is 1000 km, so ~2 GeV peak energy.

Density is approximate from CRUST2.0 (~2.8 g/cm^3). Z/A is set to a round 0.5.

◆ SetUseCache()

void PMNS_Base::SetUseCache ( bool u = true )

virtualinherited

Turn on/off caching of eigensystems. This can save a lot of CPU time by avoiding recomputing eigensystems if we've already seen them recently. Especially useful when running over multiple earth layers and even more if multiple baselines will be computed, e.g. for atmospheric neutrinos.

Parameters

u	- flag to set caching on (default: true)
