未来SPPC轻子-强子对撞机上复合电子的单次产生

Single production of composite electrons at the future SPPC-based lepton-hadron colliders

A. Caliskan

摘要:

我们考虑了在未来的基于SPPC的电子-质子对撞机上产生自旋为1/2的激发电子,质心能量为$8.4$,$11.6$,$26.6$和$36.8$ TeV。这些外来粒子的预测在复合模型。我们用$ep\rightarrow e^{\star}X\rightarrow eγX$过程计算了激发态电子的产生截面,并着重研究了激发态电子的光子衰减通道。在最终状态的电子和光子的赝快度和横向动量分布已被绘制,以确定最适合于发现的激发电子的运动学切割。通过应用这些削减,我们计算$2σ$,$3σ$和$5σ$轮廓图的统计意义的预期信号在参数空间($L$,$m^{\star}$),其中$L$表示的积分光度的对撞机和$m^{\star}$是复合电子的质量。

英文摘要:

We consider the production of excited electrons with spin-1/2 at the future SPPC-based electron-proton colliders with center-of-mass energies of $8.4$, $11.6$, $26.6$ and $36.8$ TeV. These exotic particles are predicted in the composite models. We calculate the production cross-sections and concentrate on the photon decay channel of the excited electrons with the process of $ep\rightarrow e^{\star}X\rightarrow eγX$ . The pseudorapidity and transverse momentum distributions of the electrons and photons in the final-state have been plotted in order to determine the kinematical cuts best suited for discovery of the excited electrons. By applying these cuts we compute $2σ$, $3σ$ and $5σ$ contour plots of the statistical significance of the expected signal in the parameter space ($L$, $m^{\star}$), where $L$ denotes the integrated luminosity of the collider and $m^{\star}$ is the mass of the composite electrons.
