PPPC 4 DM ID: A Poor Particle Physicist Cookbook for Dark Matter Indirect Detection
摘要：
我们提供的成分和食谱计算信号的TeV级暗物质湮灭和衰变在银河系和超越。对于每个DM通道，我们提出了电子和正电子，反质子，反氘，γ射线，中微子和反中微子e，μ，τ在生产，计算高统计模拟的能谱。通过比较Pythia和Herwig事件发生器产生的结果，我们估计了Monte Carlo不确定性。然后，我们提供了在银河系中的带电粒子的传播函数，几个DM分布配置文件和传播参数集。电子和正电子的传播进行了改进的半分析方法，考虑到位置依赖的能量损失在银河系。利用这样的传播函数，我们计算了电子和正电子，反质子和反氘核在地球位置的能谱。然后，我们提出的伽马射线通量，无论是从即时发射和逆康普顿散射的星系晕。最后，我们提供了河外伽马射线的光谱。所有结果都以数字形式提供，随时可以使用。
英文摘要：
We provide ingredients and recipes for computing signals of TeV-scale Dark Matter annihilations and decays in the Galaxy and beyond. For each DM channel, we present the energy spectra of electrons and positrons, antiprotons, antideuterons, gamma rays, neutrinos and antineutrinos e, mu, tau at production, computed by high-statistics simulations. We estimate the Monte Carlo uncertainty by comparing the results yielded by the Pythia and Herwig event generators. We then provide the propagation functions for charged particles in the Galaxy, for several DM distribution profiles and sets of propagation parameters. Propagation of electrons and positrons is performed with an improved semi-analytic method that takes into account position-dependent energy losses in the Milky Way. Using such propagation functions, we compute the energy spectra of electrons and positrons, antiprotons and antideuterons at the location of the Earth. We then present the gamma ray fluxes, both from prompt emission and from Inverse Compton scattering in the galactic halo. Finally, we provide the spectra of extragalactic gamma rays. All results are available in numerical form and ready to be consumed.
