Abstract

This analysis focuses on probing the lepton portal dark matter using Monte Carlo simulated samples from electron-positron collisions at the International Linear Collider (ILC) of 500 GeV center of mass energy with an integrated luminosity of 1000 fb⁻¹. The study examines a benchmark scenario where the dark matter is a scalar particle produced as a daughter particle of the vector-like lepton. The signal topology consists of missing transverse energy and dilepton. If no new physics is discovered, the study sets 95% confidence level exclusion limits on the mass of vector-like leptons.

在ILC上研究在\( \sqrt{s} \) = 500 GeV的e+ e -碰撞中，类矢量轻子衰变成电子并丢失横向能量

本文的分析重点是利用蒙特卡罗模拟的500 GeV质能中心的国际直线对撞机（ILC）正电子碰撞的样品探测轻子入口暗物质，其综合光度为1000 fb−1。该研究考察了一种基准情景，即暗物质是一种标量粒子，是类矢量轻子的子粒子。信号拓扑结构由缺失横能量和双轻子组成。如果没有发现新的物理现象，该研究将对类矢量轻子的质量设定95%的置信度排除限。

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
