弹性势:在大型强子对撞机上发现顶夸克弹性产生的建议

Elastic Potential: A proposal to discover elastic production of top quarks at the Large Hadron Collider

James Howarth

摘要:

在这封信中,我提出的动机和一个例子的分析方法,发现在大型强子对撞机使用前向质子标签的顶夸克对的弹性生产,包括目前的理论工具和实验接受的概述。我表明,它是有可能发现的半弹性过程中,只有300 PB的${^{-1}}$的数据,但完全弹性的情况下,目前是遥不可及的。我还说明了前向质子标签的使用如何导致顶夸克(分别为$<0.39\cdot10^{-5}$和$<0.97\cdot10^{-5}$的$t\rightarrow uγ$和$t\rightarrow cγ$形式)变味中性流衰变的分支比受到限制,这两种物质都将超过现有的世界极限至少一个数量级。

英文摘要:

In this letter, I present the motivation and an example analysis method for discovering the elastic production of top-quark pairs at the LHC using forward proton tags, including an overview of the current theoretical tools and experimental acceptance. I show that it is possible to discover the semi-elastic process with only 300 pb${^{-1}}$ of data but that the fully-elastic case is currently out of reach. I also illustrate how the use of forward proton tags can result in limits on the branching ratio for flavor changing neutral current decays of the top quark of the form $t\rightarrow uγ$ and $t\rightarrow cγ$ of $<0.39\cdot10^{-5}$ and $<0.97\cdot10^{-5}$, respectively, both of which would surpass the existing world limits by at least an order of magnitude.
