Sub-modules

flavio.physics.bdecays.bvll.amplitudes

Functions for constructing the helicity amplitudes

flavio.physics.bdecays.bvll.lfv

Observables in lepton flavour violating decays $B\to V\ell\ell^\prime$

flavio.physics.bdecays.bvll.nonfactorizable

Functions for spectator scattering corrections to $B\to V\ell^+\ell^-$ decays.

This includes weak annihilation, chromomagnetic contributions, and light quark-loop spectator scattering.

flavio.physics.bdecays.bvll.observables

Functions for exclusive $B o V\ell^+\ell^-$ decays.

flavio.physics.bdecays.bvll.observables_bs

Functions for exclusive $B_s o V\ell^+\ell^-$ decays, taking into account the finite life-time difference between the $B_s$ mass eigenstates, see arXiv:1502.05509.

flavio.physics.bdecays.bvll.qcdf

QCD factorization corrections to $B\to V\ell^+\ell^-$ at low $q^2$

flavio.physics.bdecays.bvll.qcdf_interpolate

Functions for interpolated version of the QCDF spectator scattering corrections.

Rationale for this is that a) The QCDF corrections are very small, in fact smaller than hadronic uncertainties for most observables (except maybe isospin asymmetries) b) They are very costly computing-wise as they invo...

flavio.physics.bdecays.bvll.subleading

Functions to parametrize subleading hadronic effects in $B\to V\ell^+\ell^-$ decays.
