在LHC使用弦Regge激发与弦球的喷流产生的弦论

String Theory at LHC Using Jet Production From String Regge Excitations vs String Balls

Gouranga C. Nayak

摘要:

如果我们在LHC的第二次运行中在$\sqrt{s}$ = 14 TeV的$pp$碰撞中发现额外的维度,那么弦质量尺度$M_s$可以是$\sim$ TeV,我们应该在LHC的$2 \rightarrow 2$部分子碰撞中通过弦Regge激发产生QCD喷流。在哈格多恩温度下,弦球也可以通过热辐射产生QCD喷流。本文研究了LHC上$\sqrt{s}$ = 14 TeV的$pp$碰撞中弦Regge激发与弦球激发的喷流产生,并与标准模型QCD喷流作了比较。我们发现弦Regge激发产生的高$p_T$喷注比弦球和标准模型QCD喷注产生的大。我们还发现共振的射流产生截面在字符串Regge激发的情况下,这是在其他两种情况下没有。因此,TeV尺度的高$p_T$喷流可以是一个很好的签名,以研究字符串Regge激发的$pp$碰撞在$\sqrt{s}$ = 14 TeV的LHC。

英文摘要:

If we find extra dimensions in the second run of the LHC in the $pp$ collisions at $\sqrt{s}$ = 14 TeV, then the string mass scale $M_s$ can be $\sim$ TeV and we should produce QCD jets in $2 \rightarrow 2$ partonic collisions via string Regge excitations at the LHC. QCD jets can also be produced from string balls via thermal radiation at Hagedorn temperature. In this paper we study jet production from string Regge excitations vs string balls in $pp$ collisions at $\sqrt{s}$ = 14 TeV at LHC and make a comparison with the standard model QCD jets. We find that high $p_T$ jet production from string Regge excitations can be larger than that from string balls and from standard model QCD jets. We also find resonances in the jet production cross section in string Regge excitation scenario which is absent in the other two scenarios. Hence TeV scale high $p_T$ jets can be a good signature to study string Regge excitations in the $pp$ collisions at $\sqrt{s}$ = 14 TeV at the LHC.
