实光子的部分子含量:天体物理意义

Parton content of the real photon: astrophysical implications

I. Alikhanov

摘要:

我们有令人信服的实验证据证明实光子具有非平凡的部分子结构。另一方面,宇宙微波背景光子与在宇宙中传播的高能粒子的相互作用在天体物理学中起着重要的作用。在这种情况下,调用部分子内容可以方便地计算涉及这些光子的不同过程的概率。作为一个例子,用部分子语言计算了反应$νγ\to W^+X$中包含共振$W^+$玻色子产生的截面。研究了中微子-光子深度非弹性散射。

英文摘要:

We possess convincing experimental evidence for the fact that the real photon has non-trivial parton structure. On the other hand, interactions of the cosmic microwave background photons with high energy particles propagating through the Universe play an important role in astrophysics. In this context, to invoke the parton content could be convenient for calculations of the probabilities of different processes involving these photons. As an example, the cross section of inclusive resonant $W^+$ boson production in the reaction $νγ\to W^+X$ is calculated by using the parton language. Neutrino--photon deep inelastic scattering is considered.
