The LHC is about to start Run 3 and the CMS experiment will be collecting its largest ever dataset. The student will join the PPD CMS group, of around 20 staff and students, which is active across analysis and operations, and the HL-LHC upgrade for CMS. The student project will cover both novel searches for physics beyond the standard model (BSM) and the development of complex algorithms to be deployed in FPGAs in the hardware trigger for the HL-LHC upgrade. Many BSM models, such as the NMSSM, have extended Higgs sectors including Higgs bosons lighter than the Higgs boson discovered at the LHC in 2012. The final states that will be exploited will include light higgs bosons, which will be reconstructed using techniques that make extensive use of neural nets such as Graph NNs. Exploiting  our long-standing collaboration with theorists within the NExT Institute, we will develop new BSM scenarios to explore using these techniques. The development of trigger algorithms for the HL-LHC level-1 hardware trigger will exploit our work on track reconstruction in FPGAs to develop novel algorithms that exploit these tracks. HLS will be used to deploy the algorithms in the trigger FPGAs.
