早期发现色子LHC

Discovering Colorons at the Early Stage LHC

Duane A. Dicus, Chung Kao, S. Nandi, Joshua Sayre

摘要:

我们研究了从欧洲核子研究中心大型强子对撞机的早期运行的数据与$\sqrt{s} = 7$ TeV的大规模超胶子的发现的前景,并假设一个集成的光度为1 fb $^{-1}$。采用唯象拉格朗日量计算了一对色矢量玻色子(色子,$\tildeρ$)衰变为四个色标量共振(超π介子,$\tildeπ$),再衰变为八个胶子的截面.我们包括$8g$、$7g1q$、$6g2q$和$5g3q$生产的主要物理背景。我们发现了丰富的信号事件和现实的削减减少背景足以建立一个$5σ$信号$m_{\tildeπ} \alt 220$ GeV或$m_{\tildeρ} \alt 733$ GeV。

英文摘要:

We investigate the prospects for the discovery of massive hyper-gluons using data from the early runs of the CERN Large Hadron Collider with $\sqrt{s} = 7$ TeV and assuming an integrated luminosity of 1 fb$^{-1}$. A phenomenological Lagrangian is adopted to evaluate the cross section of a pair of colored vector bosons (coloron, $\tildeρ$) decaying into four colored scalar resonances (hyper-pion, $\tildeπ$), which then decay into eight gluons. We include the dominant physics background from the production of $8g$, $7g1q$, $6g2q$, and $5g3q$. We find an abundance of signal events and that realistic cuts reduce the background enough to establish a $5σ$ signal for $m_{\tildeπ} \alt 220$ GeV or $m_{\tildeρ} \alt 733$ GeV.
