Lay summary

Dieser Antrag unterstützt Forschung mit dem CMS (Compact Muon Solenoid) Experiment am CERN (European Organization for Nuclear Research), das hoch energetische Proton Kollisionen des LHC (Large Hadron Collider) untersucht. Ziel ist ein umfangreicheres Verständnis der elementaren Kräfte und Teilchen zu erlangen. Insbesondere studieren wir die Eigenschaften des neu entdeckten Higgs-Bosons, suchen nach Anzeichen für die Produktion von Dunkle-Materie-Teilchen, nach neuen Arten von Quarks, sowie nach Anzeichen für Extra-Dimensionen und Substruktur in Quarks in Form von hochmassiven Resonanzen. Unsere Gruppe analysiert die Daten der 13 TeV Kollisionen am LHC, die seit dem Jahr 2015 genommen werden und über den Zeitraum der Förderung weiter aufgezeichnet werden. Wir sind außerdem beteiligt am CMS Spurdetektor (Pixel-Detektor), der präzise die Spuren und Vertices der in Kollisionen produzierten geladenen Teilchen vermisst. Wir wirken bei Kalibrationen, Hardwaretests, Austausch, Software Entwicklung und Simulationen mit. Wir konstruieren einen neuen, aufgerüsteten Pixel Detektor mit besserer Effizienz für hohe Datenraten, der im Jahr 2017 installiert wird. Für dieses Upgrade, haben wir neue Elektronik für die Datenauslese und Kommunikation mit dem Detektor, die mechanische Struktur, und ein neues Kühlungssystem in Leichtbauweise vorbereitet, sowie Auslesesystem, Stromversorgung, Kontrollsystem und Kühlsystem montiert und getestet. Im Zeitraum dieser Förderung werden wir helfen den neuen Detektor für CMS in Betrieb zu nehmen und hochwertige Daten aufzuzeichnen.

In 2015, the center of mass energy of the LHC (Large Hadron Collider) proton-proton collisions at CERN (European Organization for Nuclear Research) was upgraded from 8 to 13 TeV, providing a new opportunity to explore a regime where elusive physics beyond the standard model is expected to be hiding. This grant proposal is a continuation of the existing, funded Swiss National Science Foundation (SNF) grants of Prof. Canelli and Prof. Kilminster for Ph.D. students and post docs for particle physics research using the CMS (Compact Muon Solenoid) experiment the LHC. Profs. Canelli and Kilminster operate independent research groups, although there is synergy in their participation in the CMS pixel detector operation and upgrades. Profs. Canelli and Kilminster are also co-PIs of funded SNF grants for Maintenance and Operations (M\&O) costs of CMS. The construction of the phase 1 pixel upgrade and R\&D for phase 2 upgrades mentioned in this proposal are funded in a separate swiss-wide (University of Z\"urich, ETH Z\"urich, PSI) SNF grant for which Prof. Kilminster is the PI and Prof. Canelli is a co-PI. This proposal requests funds for a crucial two year time period (October 2016-September 2018). Not only will we exploit the 100 fb$^{-1}$ of luminosity expected in LHC Run 2 at the 13 TeV (and possibly 14 TeV) energy frontier with searches for new physics, but we will also install, commission, and operate a completely new upgraded phase 1 pixel detector, as well as begin designing the phase 2 pixel detector for installation in the 2023-2025 long shutdown that is a bridge to the High Luminosity LHC (HL-LHC) which will run until 2037 and collect 3000 fb$^{-1}$.By October 2016, a completely new 4-layer pixel detector with supply tube power, cooling, control and readout electronics will have been assembled and tested in Zurich. The main challenge of the first year of this grant will be to insert and commission this new detector into CMS, and then regain and surpass CMS performance for tracking, vertexing, secondary vertexing, as well as object identification. Over the course of this grant, Prof. Kilminster's group will continue its deep participation in heavy resonance searches with boosted jets, $b$ jets, and $\tau$ leptons that could arise in extra dimensional or composite Higgs scenarios, and which require a detailed understanding of jet substructure analysis techniques. Prof. Canelli's group will be searching for dark matter in association with top quarks and the production of heavy vector-like quarks, as well as Higgs bosons produced in association with top quarks, building upon advances in matrix element analysis techniques. The two groups are involved in various aspects of the currently installed pixel system, including pixel monitoring and DAQ software, recommissioning and calibrating the detector, on-call pixel shifts, and pixel track clustering offline software. The groups are also building the cooling tubes and mechanical structures for the phase 1 upgraded pixel detector, as well as integrating and commissioning the electronics, power supplies, fiber connections and cabling, cooling tubes, and the foreseen DAQ systems. The University of Z\"urich groups will produce a complete and tested supply tube system which will be able to power, control, cool, and readout the barrel pixel detector. Our CMS groups were founded recently in fall 2012, but we have already established group expertise in pixel detector operations and pixel detector building, while at the same time have become firmly rooted in some of the most important physics analysis topics of LHC particle physics. We will continue this progress as we integrate the next 100 fb$^{-1}$ luminosity expected in this grant period, searching for BSM physics processes, caring for a newly upgraded pixel system, and increasing our involvement in the phase 2 upgrade, which will require new detector techniques to handle the high instantaneous luminosity and integrated luminosity demands of the HL-LHC.
