标题： Probing the Heavy Quark Content of the Photon Using b Tagging at High Energy $eγ$ and $e^+e^-$ Colliders

摘要： 我们建议一种方法，利用高能$b$标记在$e^+e^-$和$e\gamma$对撞机上探测光子的夸克内容。 我们发现，重夸克标记为探测光子的夸克内容提供了一种敏感且有效的方法，特别是在低$x$区域，各种模型之间的差异最大。 这一过程与其他已在文献中研究的过程相辅相成，有助于更精确地确定光子内部的夸克和胶子分布。 显示英文摘要

摘要： We suggest a method for probing the quark content of the photon using $b$ tagging at high energy $e^+e^-$ and $e\gamma$ colliders. We find that heavy quark tagging provides a sensitive and effective probe of the quark content of the photon especially in the low $x$-region where the various models differ the most. This process is complementary to others that have been studied in the literature and can contribute to more precise determinations of quark and gluon distributions inside the photon.
