我们提供的成分和配方计算信号的TeV级暗物质湮灭和衰变在银河系及以外。对于每个DM通道,我们给出了生产时e(+/-);(p)在bar上,(d)在bar上,gamma,V-e,mu,tau((-))的能谱,通过高统计模拟计算。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。传播的e(+/-)进行了改进的半解析方法,考虑到银河系中的位置依赖的能量损失。利用这种传播函数,我们计算了地球位置上e(+/-),(p)和(d)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。
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 e(+/-); (p) over bar, (d) over bar, gamma, V-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 e(+/-) 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 e(+/-), (p) over bar and (d) over bar 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.
