论文摘要
可以将光束转储实验无缝添加到{拟议的}国际线性对撞机（ILC）程序中，因为高能电子束应在碰撞点后倾倒。 ILC梁垃圾场实验将为寻找新的长寿命颗粒提供绝佳的机会。由于其中许多可以通过罕见的标准模型颗粒衰减产生，因此我们根据Phits和Pythia8模拟在衰减中评估介子的光谱和$τ$ Lepton。作为一种动机的物理案例，我们研究了ILC Beam Dump实验中重中性瘦素的预计灵敏度。还可以通过深度非弹性散射和ILC主探测器的$ z $玻色子衰减产生重中性瘦素，我们在投影中包括。使用多轨信号，即使与其他提议的搜索相比，即使是质量和耦合，覆盖率也将大大扩展。
A beam dump experiment can be seamlessly added to the {proposed} International Linear Collider (ILC) program because the high energy electron beam should be dumped after the collision point. The ILC beam dump experiment will provide an excellent opportunity to search for new long-lived particles. Since many of them can be produced by a rare decay of standard model particles, we evaluate spectra of the mesons and $τ$ lepton at the decay based on the PHITS and PYTHIA8 simulations. As a motivated physics case, we study the projected sensitivity of heavy neutral leptons at the ILC beam dump experiment. The heavy neutral leptons can also be produced via deep inelastic scattering and $Z$ boson decay at the ILC main detector, which we include in the projection. With the multi-track signal, the reach would be greatly extended in mass and coupling, even compared with the other proposed searches.
