Long-lived particle search with timing information and e/muon g-2 from a light complex scalar
In the first part, we will discuss the physics potential of using precision timing information at the LHC in the search for long-lived particles (LLP). In comparison with the light Standard Model particle produced from the hard interactions, the decay products of massive LLPs arrives at detectors with sizable time delay. We propose new strategies to take advantage of this property, and obtain significant improvement in the sensitivity.
In the second part, we focus on the recent negative electron anomalous magnetic moment problem brought up by Davoudiasl and Marciano. We present a concise model using a light complex scalar to solve the e/muon g-2 simultaneously, without invoking the heavy vector-like leptons.
