Experimental Particle Physics

The next four-year timescale is particularly exciting with the exploitation of the LHC and upgrade developments at a critical stage. We will focus our efforts in the Higgs and top sectors for ATLAS, in the kaon sector for NA62, and in the charm and beauty sector for LHCb and in the neutrino sector at T2K and Hyper-K, including searches for BSM processes in each case. We are simultaneously entering a major construction phase which will require significant effort, building upon the synergies established between our ATLAS, LHCb and Linear Collider detector developments. We have undergone a significant transition in the neutrino sector where we have joined the T2K collaboration, contributing to its near detector upgrade through the WAGASCI/BabyMIND detectors, as a major step towards future neutrino developments. With the international community, we will contribute to the leadership needed to establish a future Linear Collider as part of the 2020 European strategy. We have developed detector development and construction capacity to contribute to our programme and have built up our technician and engineering effort in a carefully planned approach. Improved analysis techniques, well-calibrated detectors, increased computing power and theoretical input will be essential and we are at the forefront of the required developments in these areas.
Most academics are heavily involved in the CERN programme and our strategy is to generate leading-edge physics results from ATLAS, LHCb and NA62 based upon expertise developed in those experiments. Having secured high-quality completion in Run 2 with significant results in Higgs H->bb modes and top production for ATLAS, we will exploit this experience to lead future ATLAS publications. Taking advantage of our work on boosted topologies and exploiting the larger Run 3 dataset, we will explore more extreme regions of phase space and use theoretical input to guide the interpretation of our results. For LHCb, we will measure the CKM...
