报告题目:ForwArd Search ExpeRiment(FASER) at the LHC

报 告 人:李科 博士 华盛顿大学

报告时间:2019年12月30日上午9:00

报告地点:中心校区物理楼333报告厅

报告摘要:

New physics has traditionally been expected in thehigh-pT region at high-energy collider experiments. If new particles are lightand weakly-coupled, however, this focus may be completely misguided: lightparticles are typically highly concentrated within a few mrad of the beam line,allowing sensitive searches with small detectors, and even extremelyweakly-coupled particles may be produced in large numbers there. In this talk Iwill discuss the recent proposal of FASER, ForwArd Search ExpeRiment at theLHC: a detector placed480 mdownstream of the ATLAS interaction point (IP) in the very forwardregion and operated concurrently there. Long-lived, weakly coupled TeV-energyparticles can traverse the intervening rock and LHC infrastructure beforedecaying inside FASER, with little background from Standard Model processes.The collimated nature of the signal allows FASER to be compact, and re-use ofcomponents from other experiments allow it to be constructed quickly andinexpensively. FASER will be installed during the current LHC long shutdown andbegin collecting data in 2021.
