LHC上UED模型中第二类KK规范玻色子的产生率

Production Rate of Second KK Gauge Bosons in UED Models at LHC

Shigeki Matsumoto, Joe Sato, Masato Senami, Masato Yamanaka

摘要:

我们在最小普适额外维(MUED)模型中计算了LHC中第二个Kaluza-Klein(KK)光子$γ^{(2)}$和Z玻色子$Z^{(2)}$的产生率,包括所有重要的过程.在强子对撞机实验中,$γ^{(2)}$和$Z^{(2)}$对于区分MUED模型和其他TeV尺度模型起着至关重要的作用。为了讨论判别和计算它们的产生率,我们导出了含有KK数破坏算子的有效拉格朗日量。我们表明,KK数违反过程是非常重要的紧致化规模大于800 GeV。我们发现,当积分亮度为100 fb时,在400 GeV ~ 2000 GeV的紧致化标度范围内产生了10 $^6$ ~ 10 $^2$的$γ^{(2)}$和$Z^{(2)}$.

英文摘要:

We calculate the production rates of the second Kaluza-Klein (KK) photon $γ^{(2)}$ and Z boson $Z^{(2)}$ at the LHC including all significant processes in the minimal universal extra dimension (MUED) model. For discrimination of the MUED model from other TeV scale models in hadron collider experiments, $γ^{(2)}$ and $Z^{(2)}$ play a crucial role. In order to discuss the discrimination and calculate their production rates, we derive effective Lagrangian containing KK number violating operators. We show that KK number violating processes are extremely important for the compactification scale larger than 800 GeV. We find that, with an integrated luminosity of 100 fb$^{-1}$, $γ^{(2)}$ and $Z^{(2)}$ are produced 10$^6$ - 10$^2$ for the compactification scale between 400 GeV and 2000 GeV.
