论文摘要
支持对暗物质需求(DM)颗粒的纯粹引力证据令人信服,并基于银河系到宇宙学量表的观测。到目前为止,有希望的弱相互作用的巨大颗粒场景已经避免了检测,激发了DM的替代模型。我们考虑涉及超重黑物质(SHDM)的场景,可能会通过原始黑洞(PBH)发射,并且可以衰变或歼灭超高能源(UHE)中微子和光子。观察具有能量的光子$ e \ ge 10^{11} $ GEV的观察将暗示存在全新的物理现象,或者对DM模型有所了解。只有超高的能量宇宙射线观测值才能通过测量UHE光子引起的广泛的空气阵雨来检测这种衰减产物。使用Uhe宇宙光线上的上限超过$ 10^{11.3} $ gev,暗示$ j(> 10^{11.3}〜{\ rm {\ rm {gev}})<3.6 \ times 10^{ - 5} - 5} - 5} $ $ 90 \%$ c.l.由Pierre Auger天文台报道,我们获得了质量为$ 10^{15} \ le m_ {x} \ le 10^{17} $ GEV的DM颗粒寿命的全局限制。此处得出的约束是新的,覆盖了尚未探索参数空间的区域。我们将结果与未来诗歌和JEM-EUSO实验的预计约束进行了比较,以量化这些任务将获得的改进。 此外,假设早期PBHS统治时期引入了独特的光谱中断,$ f _ {\ ast} $,在引力波谱中,其频率与SHDM质量相关,我们映射了$ f _ {\ ast} $ f _ {\ AST} $ _______________的潜在探针和dm颗粒量的潜在探针和限制。
The purely gravitational evidence supporting the need for dark matter (DM) particles is compelling and based on Galactic to cosmological scale observations. Thus far, the promising weakly interacting massive particles scenarios have eluded detection, motivating alternative models for DM. We consider the scenarios involving the superheavy dark matter (SHDM) that potentially can be emitted by primordial black holes (PBHs) and can decay or annihilate into ultrahigh-energy (UHE) neutrinos and photons. The observation of a population of photons with energies $E\ge 10^{11}$ GeV would imply the existence of completely new physical phenomena, or shed some light on DM models. Only the ultra-high energy cosmic ray observatories have the capabilities to detect such UHE decay products via the measurements of UHE photon induced extensive air showers. Using the upper bound on the flux of UHE cosmic rays beyond $10^{11.3}$ GeV implying $J(>10^{11.3}~{\rm{GeV}})< 3.6\times 10^{-5}$ km$^{-2}$sr$^{-1}$y$^{-1}$, at the $90\%$ C.L. reported by the Pierre Auger Observatory, we obtain global limits on the lifetime of the DM particles with masses $10^{15}\le M_{X} \le 10^{17}$ GeV. The constraints derived here are new and cover a region of the parameter space not yet explored. We compare our results with the projected constraints from future POEMMA and JEM-EUSO experiments, in order to quantify the improvement that will be obtained by these missions. Moreover, assuming that an epoch of early PBHs domination introduces a unique spectral break, $f_{\ast}$, in the gravitational wave spectrum, the frequency of which is related to the SHDM mass, we map potential probes and limits of the DM particles masses on the $f_{\ast}-M_{X}$ parameter space.
