| 英文摘要 | Light Higgsinos below several hundred GeV are favored or required by the naturalness of low-energy supersymmetry. If only Higgsinos are light while other sparticles are sufficiently heavy, we have the so-called light Higgsino scenario. Confronted with the muon g - 2 data, this scenario is examined in this work. Since in this scenario the lightest sparticle is Higgsino-like, we need to also consider the dark matter constraints. Assuming a light Higgsino mass parameter mu in the range of 100-400 GeV while gaugino mass parameters above TeV, we explore the parameter space under the muon g - 2 data and the dark matter constraints. We find that, to explain the muon g - 2 anomaly at 2 sigma, the winos and sleptons are, respectively, upper bounded by 3 TeV and 800 GeV. In this case, we find that the light Higgsino-like dark matter can sizably scatter with nucleon and thus the allowed parameter space can be covered almost fully by the future LZ dark matter detection project. We also perform a Monte Carlo simulation to figure out the potential of High-Luminosity Large Hadron Collider (HL-LHC) to detect the light sleptons in this scenario. It turns out that compared with the current LHC limits, the HL-LHC can further cover a part of the parameter space. |
