Despite the discovery of the standard model (SM) Higgs boson, there are still unanswered questions that are not explained by the SM, such as the nature of the chiral structure of weak interactions. During Run-1 at the LHC, no clear signs for physics beyond the SM were seen, but there were a few hints of possible new physics. One particular hint was a 2.8\sigma excess seen at the CMS experiment in the search for a heavy right-handed W and heavy neutrino. These particles arise when a left-right symmetry is added to the electroweak sector. In this seminar, I will discuss the Run-1 excess and show preliminary results from the current search with CMS at 13 TeV for a right-handed W in the two leptons plus two jets final state. Additionally, I will discuss the high-luminosity upgrade of the CMS tracker focusing on a proposed track-trigger system to be realized using FPGA technology.
