### Lay Summary (German)

Einige der wichtigsten wissenschaftlichen Fragen, denen das CMS Experiment am LHC des CERN nachgeht, ist die genauere experimentelle Charakterisierung des im Jahre 2012 gefundenden Higgsbosons sowie die Suche nach Physik jenseits des Standardmodells. Dieses Gesuch widmet sich diesen Fragen in drei Datenanalyse-Ansätzen. Weiterhin unterstützt dieses Gesuch den Upgrade einer Komponente des CMS Detektors, die im Jahre 2016 eingebaut werden wird.
Lay summary

Im Jahre 2012 haben die beiden grossen Experimente des Large Hadron Colliders (LHC) am europäischen Teilchenphysikforschungszentrums CERN das Higgsboson entdeckt. Eine wichtige Komponente dieses Gesuchs ist die genaue Bestimmung seiner Eigenschaften mittels des Compact Muon Solenoid (CMS) Experiments. Abweichungen von Eigenschaften des gefundenen Teilchens von denen im Standardmodell vorausgesagten würden einen indirekten Hinweis auf Physik jenseits des Standardmodells liefern. Dieses Projekt widmet sich der Messung von Prozessen, die eine Bestimmung der Kopplungen des Higgsbosons an schwere Quarks (bottom und top quarks) ermöglicht. Eine weitere Komponente dieses Projektes ist die Suche nach einer direkten Manifestation neuer Physik in Form der Erzeugung supersymmetrischer Teilchen, die markante Zerfallsignaturen im Detektor hinterlassen. Eine von Forschern der ETH entwickelte Methode benutzt zum Nachweis der Supersymmetrie (SUSY) Leptonen unterschiedlicher Ladung, die zusammen mit einem Z-Boson erzeugt werden. Eine weitere Methode macht sich den Endzustand mit Leptonen gleicher Ladung zunutze, eine Signatur, die im Standardmodell nur selten vorkommt.  Dieses Projekt unterstützt weiterhin die Arbeit von ETH Wissenschaftlerinnen und Wissenschaftler am Upgrade des CMS Barrel-Pixel-Detektors für die "Phase 1" Ausbauphase des LHC. Das abgedeckte Aufgabengebiet umfasst den Test des neuen Auslesechips (ROC) und Tests des Moduldesigns. Im Gesuchszeitraum wird die Massenproduktion der Module beginnen und somit einen wichtiger Meilenstein erreicht. Diese Arbeit wird in enger Zusammenarbeit mit Mitarbeitern des Paul-Scherrer-Instituts und der Unversität Zürich durchgeführt.

### Abstract

With this continuation grant proposal, we would like to request support for our research program in high energy particle physics tackling fundamental questions of the field. The research proposed is conducted with the Compact Muon Solenoid (CMS) experiment operating at the Large Hadron Collider (LHC) at the European Center for Particle Physics (CERN). The proposal is driven by the preparation for the LHC running period at a center of mass (CM) energy of 13- 14 Tera-Electronvolt (TeV) foreseen to start in spring 2015 which will provide excellent prospects for the exploration of physics at the TeV energy scale. We also prepare for the upgrades of the CMS detector (phase 1 and phase 2) necessitated by the continuing and future improvements of the LHC accelerator. With the spectacular discovery of a Higgs particle at CERN, a success to which scientists of this proposal have contributed in a leading manner, the measurement of its properties becomes a high priority in order to elucidate whether the new particle indeed plays a crucial role in the mechanism of electroweak symmetry breaking. We will attempt to firmly establish the existence of the Higgs boson decaying into two b-quarks using the production mode in association with a vector boson (W or Z). This process allows the extraction of the couplings of the Higgs boson to b-quarks andWor Z-bosons as well as a determination of the spin and parity of the newly found particle. We improve this long-standing effort of the CMS ETH group by exploiting jet substructure techniques to identify highly boosted b-jets. These methods will also be employed for a new initiative proposed by this funding request which focuses on Higgs boson production in association with top quarks. This process allows the extraction of the top-Yukawa coupling to the Higgs field, a fundamental parameter of electroweak symmetry breaking.We continue the search for SUSY using the dilepton final state, employing a kinematic method (Jet-Z-balancing) for leptons of opposite charge sign to estimate SM backgrounds from data. The search for SUSY in the like-sign dilepton final state is not only sensitive to the production of SUSY particles via the strong force, but with a suitable optimization is also sensitive to electroweak SUSY production, a channel which becomes important if the mass hierarchy for SUSY squarks and gluinos is beyond the energy reach of the LHC. A SM background for the dilepton SUSY searches is the production of a top-anti-top quark pair in association with a vector boson (W or Z). Scientists of this proposal have made a successful first measurement of this process at a LHC CM energy of 7 TeV and we are in the process of publishing the result based on the 8 TeV data set. This measurement made on the 13 TeV data set will naturally lead to a complementary measurement of top quark associated Higgs production mentioned above using the multi-lepton final state.Our proposal further requests support to continue hardware work for the upgrades of one of the key components of the CMS detector, the barrel pixel detector, foreseen for the year 2016 (phase 1) and around 2021 (phase 2). Within CMS several consortia have formed to collaborate on the phase 1 upgrade, with ETH Zurich, PSI and University of Zurich forming the Swiss consortium. The role of the ETH Zurich group within the Swiss consortium will be the important task of module testing and quality assurance.
