Precision Timing at the LHC and Beyond (video)

Si Xie, Research Assistant Professor of Physics, Caltech

To cope with the unprecedented rate of particle collisions and high intensity environment of the high luminosity upgrade of the Large Hadron Collider (LHC) at CERN, new particle detector systems capable of measuring very precise timestamp have been developed by the LHC experiments. By using the time coordinate, a dimension that has so far been under-utilized at the LHC experiments, these new detector systems allow us to pinpoint the one particle collision of greatest interest among the 200 collisions that are produced by the LHC every 25ns. I will discuss the design and R&D of these precision timing detector systems, their impact on the LHC physics program, as well as novel and less explored physics that are enabled by these detectors. Finally, I will discuss future opportunities in the area of precision timing detector development, with particular emphasis on current and future research collaboration between the fields of high energy physics and quantum information science.
