“…(4) and (5). The γ-ray intensity and spectrum from DM annihilation is constructed by summing over all of the annihilation channels: r(s, ψ)), (6) where dN f γ /dE is the number of γ rays per annihilation into the f f channel, generated from the PPPC 4 DM ID package [55] based on fits to Pythia 8.1 [56], and η = 2(4) for Majorana (Dirac) DM. The integral is the J-factor, obtained by integrating the DM density ρ 2 (x) corresponding to either an NFW or NFW-c distribution, Eq.…”

Dark matter interpretation of the Fermi -LAT observation toward the Galactic Center

The center of the Milky Way is predicted to be the brightest region of γ-rays generated by selfannihilating dark matter particles. Excess emission about the Galactic center above predictions made for standard astrophysical processes has been observed in γ-ray data collected by the Fermi Large Area Telescope. It is well described by the square of an NFW dark matter density distribution. Although other interpretations for the excess are plausible, the possibility that it arises from annihilating dark matter is valid. In this paper, we characterize the excess emission as annihilating dark matter in the framework of an effective field theory. We consider the possibility that the annihilation process is mediated by either pseudo-scalar or vector interactions and constrain the coupling strength of these interactions by fitting to the Fermi Large Area Telescope data for energies 1-100 GeV in the 15 • × 15 • region about the Galactic center using self-consistently derived interstellar emission models and point source lists for the region. The excess persists and its spectral characteristics favor a dark matter particle with a mass in the range approximately from 50 to 190 (10 to 90) GeV and annihilation cross section approximately from 1×10 −26 to 4×10 −25 (6×10 −27 to 2×10 −25 ) cm 3 /s for pseudo-scalar (vector) interactions. We map these intervals into the corresponding WIMP-neutron scattering cross sections and find that the allowed range lies well below current and projected direct detection constraints for pseudo-scalar interactions, but are typically ruled out for vector interactions.

Z gauge bosons arise in many particle physics models as mediators between the dark and visible sectors. We exploit dark matter complementarity and derive stringent and robust collider, direct and indirect constraints, as well as limits from the muon magnetic moment. We rule out almost the entire region of the parameter space that yields the right dark matter thermal relic abundance, using a generic parametrization of the Z -fermion couplings normalized to the Standard Model Z-fermion couplings for dark matter masses in the 8 GeV-5 TeV range. We conclude that mediators lighter than 2.1 TeV are excluded regardless of the DM mass, and that depending on the Z − f ermion coupling strength much heavier masses are needed to reproduce the DM thermal relic abundance while avoiding existing limits.

Abstract:We study the differences in the gamma-ray spectra simulated by four Monte Carlo event generator packages developed in particle physics. Two different versions of PYTHIA and two of HERWIG are analyzed, namely PYTHIA 6.418 and HERWIG 6.5.10 in Fortran and PYTHIA 8.165 and HERWIG 2.6.1 in C++. For all the studied channels, the intrinsic differences between them are shown to be significative and may play an important role in misunderstanding dark matter signals.
