We search for the doubly charged leptons () predicted in composite models including extended weak isospin multiplets, namely, and , at the Future Circular Collider- (FCC-) based energy-frontier electron-proton colliders with the center-of-mass energies of  TeV,  TeV, and  TeV, respectively. We deal with the process, calculate the production cross sections, and give the normalized transverse momentum and pseudorapidity distributions of final-state electron to obtain the kinematical cuts for the discovery. We show the statistical significance (SS) of the expected signal yield as a function of doubly charged lepton mass ( plots) to attain the doubly charged lepton discovery mass limits for both the and . It is obtained that discovery mass limits on the mass of doubly charged lepton for () are TeV, TeV, and TeV for  TeV,  TeV, and  TeV, respectively.

基于FCC的能量前沿电子-质子对撞机的双电荷轻子搜索电位

我们搜索包含扩展弱等位旋多重峰的复合模型中预测的双电荷轻子（），即 和 ，在未来循环Collider-（FCC-）基于能量的前沿电子质子撞机用的中心的质量能量 TeV，  TeV和  TeV，分别。我们处理进行处理，计算生产截面，并给出归一化的横向动量和最终态电子的假快速分布，以获得用于发现的运动学切变。我们显示了预期信号产生率的统计显着性（SS）作为双电荷轻子质量（图）的函数，以实现两个传感器的双电荷轻子发现质量极限 和 。结果发现，对于双电荷轻子的质量的发现质量极限为 （）是TeV，TeV和TeV TeV，  TeV和  TeV，分别。
