论文摘要
在最近的一篇论文中指出,观察到的旧,冷中子星(NS)的冷却速率可以为中子向镜面中子的过渡速率($ n-n'$)提供上限。此限制非常严格,以至于在当前对该过程的陆地搜索中,它将排除任何发现$ n \ to n'$振荡的任何发现。在这个至关重要的结论中,我们对此建议进行了严格的分析,并指出了几乎精确的镜像模型中$ n \ to n'$振荡的有趣的新效果,这显着影响了这一界限。新元素是$β$ decay $ n'\ to p' + e' + \barν'_ {e} $,它在NS Core中创建了镜子粒子$ n'$,$ n'$,$ p'$,$ e'$和$ d'U的云。 $ e'ub可以通过$ e-e-e'$散射产生的$ n \ to n'$过渡产生的能量,这是由于在镜子粒子中存在(分钟)毫米的存在。这种能量通过快速镜子bremsstrahlung发射为未观察到的镜面光子,从而使该上限放松。
It was pointed out in a recent paper that the observed cooling rate of old, cold neutron stars (NS) can provide an upper limit on the transition rate of neutron to mirror neutron ($n-n'$). This limit is so stringent that it would preclude any discovery of $n \to n'$ oscillation in the current round of terrestrial searches for the process. Motivated by this crucially important conclusion, we critically analyze this suggestion and note an interesting new effect present in nearly exact mirror models for $n \to n'$ oscillation, which significantly affect this bound. The new element is the $β$ decay $n' \to p'+ e' +\barν'_{e}$, which creates a cloud of mirror particles $n'$, $p'$, $e'$ and $D'$ inside the NS core. The $e'$ can "rob" the energy generated by the $n \to n'$ transition via $e-e'$ scattering enabled by the presence of a (minute) milli-charge in mirror particles. This energy is emitted as unobserved mirror photons via fast mirror bremsstrahlung leading to a relaxation of this upper limit.
