论文摘要
粒子物理的标准模型以外的许多理论预测了在存在磁场的情况下与光子混合的轴突状颗粒（ALP）的存在。寻找阿尔卑斯山的一种突出的间接方法是寻找由天体物理磁场中的ALP-Photon混合引起的大伽马射线光谱的不规则性。这就需要对地球和大黄花之间的磁场进行建模。到目前为止，仅使用了Blazar射流中磁场的非常简单的模型。在这里，我们通过将磁场结构模型施加到Potter＆Cotter提出的喷气模型上，研究了更复杂的喷射磁场配置对这些光谱不规则的影响。我们将MRK 501的伽马射线光谱与Alps模拟，并将它们拟合到NO-ALP光谱，扫描ALP和B场配置参数空间，并表明喷气机可以是一个重要的混合区域，能够探测$ M_A \ M_A \ M_A \ SIM \ SIM $ 1-1000 NEV和$ g_ $ g_ $ g_ $ gtim $ gtry $ $ gtry $ $ gtresim $ $ gtrip $ gtrtipes $ gtrtipes $ $ gtrtipe GEV $^{ - 1} $。但是，磁场结构的合理（即与观察结果一致）的变化可能会对混合产生巨大影响。对于高度磁化簇中的喷气式飞机，在群集中混合可以使射流中的混合混合。这意味着使用Perseus群集中使用混合的当前约束仍然有效。
Many theories beyond the Standard Model of particle physics predict the existence of axionlike particles (ALPs) that mix with photons in the presence of a magnetic field. One prominent indirect method of searching for ALPs is to look for irregularities in blazar gamma-ray spectra caused by ALP-photon mixing in astrophysical magnetic fields. This requires the modelling of magnetic fields between Earth and the blazar. So far, only very simple models for the magnetic field in the blazar jet have been used. Here we investigate the effects of more complicated jet magnetic field configurations on these spectral irregularities, by imposing a magnetic field structure model onto the jet model proposed by Potter & Cotter. We simulate gamma-ray spectra of Mrk 501 with ALPs and fit them to no-ALP spectra, scanning the ALP and B-field configuration parameter space and show that the jet can be an important mixing region, able to probe new ALP parameter space around $m_a\sim$ 1-1000 neV and $g_{aγ}\gtrsim$ $5\times10^{-12}$ GeV$^{-1}$. However, reasonable (i.e. consistent with observation) changes of the magnetic field structure can have a large effect on the mixing. For jets in highly magnetized clusters, mixing in the cluster can overpower mixing in the jet. This means that the current constraints using mixing in the Perseus cluster are still valid.
