Dark Matter at the LHC and L1 Track Trigger at the HL-LHC
Abstract: Although there is enough evidence for the existence of dark matter from astronomical observations, its nature matter remains one of the most important questions in high-energy physics. There are four known experimental approaches to carry out dark matter searches: direct detection, indirect detection, particle colliders, and astrophysical probes.
In this talk, I will review a particular search for dark matter produced in association with top pairs from 13-TeV proton-proton collision data at the Large Hadron Collider (LHC), collected by the CMS detector. Findings from this search at about 36/fb integrated luminosity will be compared with results from direct and indirect detection experiments. The discovery potential for dark matter and physics beyond the Standard Model will be significantly boosted at the High-Luminosity LHC, which is expected to provide 3000/fb integrated luminosity at 14 TeV.
After showing plans for the CMS tracker upgrade, I will present the current work toward an innovative level-1 track trigger. In particular, I will describe a proposal for transfering and reformatting copious data from the tracker back-end to the track trigger engine, I will show high-speed link (10 Gbps and above) studies via the Aurora 64b/66b protocol, and I will discuss recent results for a fast and efficient track fit algorithm in ultrascale FPGAs.
