Das Institut für Teilchen- und Astrophysik der ETH Zürich ist führend involviert im CMS Experiment am Large Hadron Collider des CERN. Der Fokus der Forschungsaktivitäten liegt auf den Studien des Higgs Bosons, der Suche nach supersymmetrischen Teilchen, sowie den Erneuerungsarbeiten am Detektor. Dieses Projekt hat zum Ziel, dass die ETH Gruppe weiterhin eine führende Rolle bei diesen Aktivitäten einnehmen wird.
Lay summary
Seit 2015 läuft der sogenannte "Run 2" des LHC Beschleunigers am CERN, bei den höchsten bisher erreichten Energien. Die ETH Gruppe von Prof. G. Dissertori, welche führend im CMS Experiment involviert ist, war massgeblich an den bisherigen grossen Erfolgen des Experiments, speziell an der Entdeckung des Higgs Bosons, beteiligt. Nun geht es vor allem darum, die Suche nach bisher unentdeckten Teilchen, z.B. sogenannten supersymmetrischen Teilchen, fortzuführen, sowie die Eigenschaften des neu entdeckten Higgs Bosons so genau wie möglich zu vermessen. Ziel des vorliegenden Projekts ist es, die führende Rolle der ETH Gruppe bei diesen Aktivitäten zu erhalten und möglicherweise auszubauen. Ein Schwerpunkt wird die optimale Ausnutzung des elektromagnetischen Kalorimeters sein, u.a. zur genauen Vermessung von Photonen. Ein weiterer Aspekt der Arbeiten besteht in der Entwicklungs- und Forschungsarbeit im Hinblick auf die Erneuerung von Komponenten des elektromagnetischen Kalorimeters, vorgesehen ab ca. 2023.
Diese Grundlagenforschung erfolgt in einem sehr kompetitiven internationalen Umfeld. Das Projekt ermöglicht den beteiligten Doktorierenden und Postdoktoranden, am weltweit bedeutensten Projekt der Teilchenphysik führende Beiträge zu leisten.

Abstract

This funding proposal seeks support by the SNF in order to carry out a world-class research program in the context of the CMS experiment at the Large Hadron Collider (LHC) at CERN, Geneva. The first years of very successful LHC running at 7, 8 and 13 TeV have shown that CMS in general, and the ETH group within CMS in particular, have taken important roles in this unique quest for Physics beyond the Standard Model (SM) and for understanding the mechanism behind electroweak symmetry breaking. In particular, the discovery of a new scalar boson with mass ~125 GeV, consistent with the long-sought Standard Model Higgs boson, represents a major breakthrough for the whole field.The overarching aim of the CMS groups of ETH Zurich, led by Prof. G. Dissertori, Prof. C. Grab and Prof. R. Wallny, is to maintain and consolidate the leadership role of the ETH group within CMS on a level commensurate with the important investments made by the Swiss funding agencies into the CMS experiment (Electromagnetic Calorimeter (ECAL), Barrel Pixel Detector, Solenoid, Silicon Strip Tracker). This continuation proposal, under the leadership of the PI G. Dissertori, specifically requests funds to exploit the potential of CMS for precision studies of the SM Higgs sector and for searches for supersymmetric particles, as well as to contribute to the so-called Phase-2 upgrade of the ECAL barrel readout electronics and to the development of a novel Precision Timing Layer. Currently we are in the middle of the LHC Run 2, with the accelerator showing excellent performance in terms of delivered luminosity at a centre-of-mass energy of 13 TeV. This promises well for obtaining a significant data set by the end of this run in late 2018, that can be scrutinized during the next long shutdown of the LHC (2019-2020), while at the same time also developing novel methods and preparing for the subsequent Run 3 at 14 TeV centre-of-mass energy. In view of this particular period ahead of us, this proposal presents a streamlined physics analysis program with clear emphasis on precision studies of the Higgs boson (differential measurements of Higgs production using its di-photon decay channel and limits on the Higgs self-interaction via the search for di-Higgs production), and on searches for supersymmetric particles by scrutinizing so-far unexplored regions of phase space. The proposed research program builds on our previous developments and recognized expertise in terms of event reconstruction and analysis software. This period also coincides with an important phase of the CMS activities targeting the Phase-2 upgrades, to which we intend to contribute in an essential manner with focus on the ECAL barrel electronics and the recently proposed Precision Timing Layer (barrel part).The planned research efforts are in excellent synergy, complementarity and close coordination with the other CMS efforts at ETH (groups of R. Wallny and C. Grab), whose focus is on the optimal Physics exploitation of the CMS Pixel detector and on its upgrades. Close ties also exist to other Swiss CMS groups at PSI and the University of Zurich. The analysis efforts of the ETH team in CMS follow a common analysis master plan, sharing the overall responsibilities in order to increase efficiency and exploit synergies between the different groups. It is very important to highlight that the CMS data analysis environment is extremely competitive, with notably very strong and large groups from the US, the UK and Germany, such as MIT, Fermilab, Imperial College and KIT, to mention a few. Given the experience gained over the last years, we are convinced to have the necessary know-how to compete with such groups and thus make visible impacts, provided strong support is given by the SNF in terms of funding for Postdocs and PhD students, thus complementing other investments related to detector operations and upgrade efforts.
