10.6. γ and ν particle spectra

Possible keyword choices for the gPP_FLAG_SPECTRUMMODEL variable:

Keyword Description
kBERGSTROM98 Bergström et al. (1998):

\(\langle {\rm d}N_{\gamma}/{\rm d}E_{\gamma}\rangle^{\rm SUSY} = 0.73/m_{\chi} \; \exp(-7.8x)/x^{1.5}\) with \(x=E/m_\chi\)
kTASITSIOMI02 Tasitsiomi et al. (2002):

\(\langle {\rm d}N_{\gamma}/{\rm d}E_{\gamma}\rangle^{\rm SUSY} = (1/m_{\chi}) \times \left[ 10/3 - 5/4\, x^{0.5} - 5/2 \,x^{-0.5} + 5/12\, x^{-1.5}\right]\) with \(x=E/m_\chi\)
kBRINGMANN08 Bringmann et al. (2008): \({\rm d}N_{\gamma}^{\rm SUSY-IC}/{\rm d}E_{\gamma}\), internal bremsstrahlung contribution (here for a pure Higgsino or Wino).
kCIRELLI11_EW Cirelli et al. (2011,2012): \({\rm d}N_{\gamma,\,\nu,\,\bar{p},\,\dots}/{\rm d}E\) from PPPC 4 DM ID (depends on the branching ratios).
kCIRELLI11_NOEW Cirelli et al. (2011,2012): same as above, but without electro-weak corrections.


 

Note

When choosing kCIRELLI11_EW/kCIRELLI11_NOEW, it is additionally possible/necessary to select one of the following options:

  • SM model final state under investigation via the parameter gSIM_FLUX_FLAG_FINALSTATE (see Keywords for possible final states). Note that this parameter must be set to gSIM_FLUX_FLAG_FINALSTATE = kGAMMA for all other spectral models listed in the table above.

  • Neutrino (physics) details, in case gSIM_FLUX_FLAG_FINALSTATE = kNEUTRINO is chosen: Besides the mixing angles of neutrino oscillation (see Section 6.4.4), the neutrino species under consideration has to be specified via the gSIM_FLUX_FLAG_NUFLAVOUR variable (see Keywords for neutrino flavours).
