We provide recipes for particle spectra in dark matter indirect searches in the form of tables. A wide range of dark matter masses from 10 GeV to 100 TeV is covered. We consider 11 primary annihilation channels:
DM DM -> e+e-, mu+ mu-, tau tau, qq (q=u,d,s), cc, bb, tt, WW, gg, ZZ, and hh.
Each file contains 13 columns: the dark matter mass, the Log of energy fraction (kinetic energy of the particle over the dark mass), and normalized spectra for 11 primary channels. The provided tables correspond to the spectra of Standard Model stable particles, i.e. of photons, positrons, electron anti-neutrinos, muon anti-neutrinos and tau anti-neutrinos.The spectra of anti-protons, and anti-atoms will be added soon.
For each particle species, we provide twelve tables which can be found in zip format. The notation of the different tables is given below:
1) The table corresponding to the central prediction for the spectra is denoted by 'AtProduction-Hadronization1-$TYPE.dat' with
$TYPE=Nuel, Numu, Nuta, Ga, Positrons which refers to the three flavors of neutrinos, photons and positrons respectively.
2) There are nine tables corresponding to the different variations of the light quark fragmentation function's parameters. These
tables are denoted by 'AtProduction-Hadronization$h-$TYPE.dat' with h=2,..,10.
3) The particle spectra corresponding to the variations of the shower evolution scale (mu_R) are denoted by 'AtProduction-Shower-Var$s-$TYPE.dat'
with s=1,2 corresponds to 1/2 mu_R and 2 mu_R.
Important advices:
i) Uncertainty on the spectra, from hadronization, is obtained from the envelope of all the variations (including the central prediction).
ii) In the variations of the parton shower evolution scale, the parameters of the hadronization function are fixed to their central value.
iii) In principle, showering uncertainties are uncorrelated to hadronization uncertainties. To obtain the full uncertainty, one might combine
