论文摘要
使用EPOS-LHC估计的抗抑郁剂生产横截面与结合后燃烧器进行了调整,以重现了在这里广泛的能量上已发表的已发表的实验数据,作为银河传播代码Galprop的输入,与现有的proton相比,与现有的Proton,氦气量,以及Boron-toparbon-carbon-carbon-carbon Batio数据进行了验证。将所得的近地抗抗耐药液(包括太阳调制)与以前的估计进行了比较。预测抗抑郁通量的总体因素为两个增量,还讨论了其起源。然而,这种抗抑郁背景的标准模型来源仍然远低于AMS-02,预期的差距,敏感性以及几种暗物质模型预测的通量。
Antideuteron production cross-sections estimated using EPOS-LHC with a coalescence afterburner, tuned to reproduce published experimental data over a wide range of energy were used here as input to the galactic propagator code GALPROP, validated with comparing to existing proton, helium fluxes as well as boron-to-carbon ratio data. The resulting near-Earth antideuteron flux, including solar modulation, is compared to previous estimates. An overall factor of two increments in the antideuteron flux is predicted, the origin of which is also discussed. However, this standard model source of antideuteron background still lies well below the AMS-02, and the expected GAPS, sensitivities, as well as the fluxes predicted by several dark matter models.
