Lay summary
Dies ist ein Antrag zur Förderung der Forschung im Rahmen des CMS (Compact Muon Solenoid) Experiments am CERN (Europäische Organisation für Kernforschung) mit hochenergetischen Protonenkollisionen am LHC (Large Hadron Collider). Die Forschungsarbeit geht die grundlegenden Schwächen des Standardmodells der Teilchenphysik an. Diese betreffen zum Beispiel den Ursprungs der Masse der Elementarteilchen, die Eigenschaften der dunklen Materie, die den Grossteil der Masse in unserem Universum ausmacht, oder das ungenügende Ausmass der CP Verletzung, um die beobachtete Asymmetrie zwischen Materie und Antimaterie im Universum zu erklären.
Der Antrag sieht ein umfangreiches Programm von Messungen und Suchen vor, die uns ermöglichen, die Ursache für die elektroschwache Symmetriebrechung zu erforschen und so ein neues Verständnis für die schwache Skala zu erhalten.
Die vorgeschlagene Forschungsarbeit benutzt das Top-Quark um diese Fragestellungen zu erforschen, da dessen aussergewöhnlich schwere Masse auf einen speziellen Zusammenhang mit der Physik ausserhalb des Standardmodells deutet. Um die besten Voraussetzungen für eine neue Entdeckung am CMS Experiment durch ein verbessertes Leistungsvermögen bei der Datennahme am HL-LHC zu schaffen, beinhaltet dieser Antrag auch das Design und die Entwicklung von Elementen für den neuen Phase 2 Pixeldetektor, insbesondere für die Erweiterung des Spurendetektors in Vorwärtsrichtung, über die jetzige Pseudorapidität von 2.5 hinaus bis nach 4.

### Abstract

The top quark, being the heaviest standard model particle, may play a special role in physics beyond the standard model. Using the CMS experiment at the Large Hadron Collider (LHC) at CERN, the research in this proposal explores the relationship of the top quark with the Higgs boson, which provides its mass, as well as the coupling of the top quark to the elusive dark matter particle. The proposal explains these research topics, and outlines analysis approaches, such as the matrix element method, that can help to achieve these goals. While the predictions of the standard model have so far been found to agree with experimental observations, some phenomena are outside of its realm. The standard model is therefore assumed to be a low-energy simplification of a larger theory. Searching for extensions to the standard model is of paramount importance in modern particle physics and has been one of the motivations for the construction of the LHC. General theoretical arguments imply that new physics is required at the TeV energy scale, which is within the sensitivity of the LHC experimentsThis proposal addresses the fundamental shortcomings of the standard model regarding the origins of the mass of fundamental particles, the nature of the dark matter that comprises most of the mass of our universe, and the lack of sufficient CP violation to explain the matter-antimatter asymmetry of the observed universe. I focus on a broad category of measurements and searches that will help elucidate the nature of electroweak symmetry breaking and our understanding of the weak scale. The proposed research uses the top quark as a probe for these questions since its exceptionally large mass could have a special connection with physics beyond the standard model. Analysis topics are proposed for a postdoctoral researcher and PhD students to address these and related questions. The LHC is performing well and the CMS experiment is collecting good quality data at a steady rate. In February 2017, CMS incorporated a new inner tracker detector, which my group helped build, called the “phase one pixel detector”, to provide improved track parameter resolutions, and also higher rate capabilities to cope with LHC data rates expected over the next few years. By 2023, the LHC will have produced 300fb-1 of luminosity at 14 TeV, and will be shut down for accelerator and detector upgrades to begin the HL-LHC program, which has a goal of 3000fb-1 of luminosity by around 2037. To maximize the discovery potential of the CMS experiment, I propose to help design and prototype a new “phase two pixel detector”, with improved capabilities for HL-LHC running, notably an extension of tracking in the forward region beyond the current pseudo-rapidity of 2.5, out to 4.0. In this proposal, I outline work packages to help accomplish the goal of extending the inner tracker coverage out to a pseudorapidity of 4.0 with a new, extended pixel detector called EPIX. This improved tracking range will provide better identification for vector boson fusion processes, and improved missing energy resolution and pileup rejection for all CMS analyses. This proposal funds PhD students and a postdoctoral researcher to develop and prototype elements of this new inner tracking detector.
