标题： High Energy Photon-Photon Collisions -

摘要： 高能光子在正负电子对撞机上的碰撞为测试量子色动力学、电弱相互作用以及标准模型的扩展提供了一个全面的实验室。 通过反向散射激光束产生的碰撞光子的亮度和能量预计将与主要的$e^+e^-$碰撞相当。 在本综述中，我们将重点研究光子-光子湮灭中的电弱理论检验，特别是$\gamma\gamma \rightarrow W^+ W^-$、$\gamma\gamma \rightarrow $希格斯玻色子以及高阶环过程，如$\gamma\gamma \rightarrow \gamma\gamma, Z \gamma$和$ZZ.$。由于每个光子都可以分解为一个$W^+ W^-$对，高能光子-光子碰撞也可以为研究$WW$碰撞和湮灭提供一个极好的无背景实验室。 我们还回顾了量子色动力学的高能$\gamma\gamma$测试，如光子结构函数的标度、$t \bar t$产生、小喷注过程和非弹性反应。 显示英文摘要

摘要： The collisions of high energy photons produced at an electron-positron collider provide a comprehensive laboratory for testing QCD, electroweak interactions, and extensions of the Standard Model. The luminosity and energy of the colliding photons produced by back-scattering laser beams is expected to be comparable to that of the primary $e^+e^-$ collisions. In this overview, we shall focus on tests of electroweak theory in photon-photon annihilation, particularly $\gamma\gamma \rightarrow W^+ W^-$, $\gamma\gamma \rightarrow $ Higgs bosons, and higher-order loop processes, such as $\gamma\gamma \rightarrow \gamma\gamma, Z \gamma$ and $ZZ.$ Since each photon can be resolved into a $W^+ W^-$ pair, high energy photon-photon collisions can also provide a remarkably background-free laboratory for studying $WW$ collisions and annihilation. We also review high energy $\gamma\gamma$ tests of quantum chromodynamics, such as the scaling of the photon structure function, $t \bar t$ production, mini-jet processes, and diffractive reactions.
