Description
Long-lived particle is well motivated for the new physics search both for collider phenomenology and dark sector. We make use of new variables related to position to search for long-lived, basing on current CMS detector and the Phase-2 Upgrade of the CMS endcap calorimeter which is a high granularity silicon-based calorimeter (HGCAL). We study the long-lived particle signal induced by long-lived sterile neutrino and long-lived Higgs portal particle. The position related variables have been developed to suppress QCD and fake track backgrounds. The final results depend on trigger performance and are generally promising.
Speaker introduction: Xiaoping Wang got her Ph.D. from Peking University, have done the first postdoc in Mainz University and is a postdoc at high energy division of Argonne National Laboratory. She has done lots of works in dark matter, neutrino and collider phenomenology.
