NuRadioMC.utilities.cross_sections.get_nu_cross_section(energy, flavors, inttype='total', cross_section_type='ctw')[source]

return neutrino cross-section

Parameters:

energy: float/ array of floats

neutrino energies/momenta in standard units

flavors: float / array of floats

neutrino flavor (integer) encoded as using PDG numbering scheme, particles have positive sign, anti-particles have negative sign, relevant are:

12: electron neutrino
14: muon neutrino
16: tau neutrino

inttype: str, array of str

interaction type. Options:

nc : neutral current
cc : charged current
total: total (for non-array type)

cross_section_type: {‘ctw’, ‘ghandi’, ‘csms’}, default ‘ctw’

defines model of cross-section. Options:

ctw : A. Connolly, R. S. Thorne, and D. Waters, Phys. Rev.D 83, 113009 (2011). cross-sections for all interaction types and flavors
ghandi : according to Ghandi et al. Phys.Rev.D58:093009,1998 only one cross-section for all interactions and flavors
csms : A. Cooper-Sarkar, P. Mertsch, S. Sarkar, JHEP 08 (2011) 042
