Lay Summary (German)

Lead
Das Standardmodell der Teilchenphysik beschreibt die fundamentalen Teilchen und Kräfte im Universum. Obwohl es in unzähligen Experimenten bestätigt wurde, gibt es noch offene Fragen und Anzeichen dafür, dass es nicht komplett ist. In diesem Projekt geht es darum, hochpräzise Detektoren zu entwickeln und benützen, um diese neue Physik zu untersuchen.
Lay summary
Spuren von Teilchen werden mit hochpräzisen Sensoren aufgezeichnet, um einerseits die Proton-Proton-Kollisionen am CERN Large Hadron Collider (LHC), und anderseits die Neutrino-Wechselwirkungen in Argon beim DUNE-Experiment am Fermilab zu untersuchen. Der LHC bietet die Möglichkeit, direkt nach neuen Teilchen zu suchen. Neutrinos haben selber Eigenschaften, wie ihre Masse, die über das Standardmodell hinausgehen und bis jetzt die einzigen Beweise für neue Physik sind. Eine Kombination dieser Forschungsthemen erweitert die Möglichkeiten, um Antworten auf die grundlegenden offenen Fragen der Teilchenphysik zu finden, und dabei könnten auch grundlegende neue Entdeckungen gemacht werden. Mit dem ATLAS-Experiment am LHC werden wir nach sogenannten supersymmetrischen Teilchen suchen, die offene Fragen im Zusammenhang mit dem absoluten Wert der Higgs Masse, oder auch der Asymmetrie zwischen Materie und Materie stehen, sowie einen Kandidaten für die Dunkle Materie im Universum liefern könnte. Wir werden die Daten analysieren, welche vom ATLAS Detektor bereits aufgezeichnet wurden und auch der nächste Upgrade ATLAS-Detektors für den HL-LHC vorbereiten. Für diesen Upgrade wird im Projekt die Hochgeschwindigkeits-Auslese mit optischen Fasern des neuen Pixeldetektors entwickelt, für welche die Universität Bern verantwortlich ist. Das System wird ab 2025 die höchte Auflösung aller Teile von ATLAS Experiment aufweisen. Für das DUNE-Experiment werden wir Studien zu physikalischen Messungen an Near Detector (ND) in Chicago durchführen, welcher die Neutrinos misst, bevor sie 1500 km weiter zum "Far Detector" in South Dakota fliegen und sich auf dem Weg in andere Neutrino Sorten umwandeln können. Dazu braucht es auch hier die leistungstärksten und präzisesten Neutrino-Detektoren: flüssig-Argon-TPCs. Sowohl das Upgrade des LHC auf das HL-LHC als auch das DUNE-Programm sind weltweit die grössten Projekte auf dem Gebiet der Hochenergiephysik und sind auch die Säulen des von CHIPP definierten Programms für Teilchenphysik in der Schweiz. Für beide Themen kommen die Methoden von Spurendetektoren, zur Datenanalyse, Datenverteilung und -analyse, sowie zur Rekonstruktion  sehr komplexer Topologien verwendet. Dieses Projekt bietet drei Doktoranden und zwei PostDocs einzigartige Möglichkeiten für Abschlussarbeiten und Forschungsthemen in der Spitzenforschung.

Abstract

We propose to explore physics beyond the Standard Model of particle physics, which is known not to be complete. The plan is to utilize high precision trackers to look at the highest energy proton-proton collisions at the CERN Large Hadron Collider (LHC) and at neutrino interactions in argon at the DUNE experiment at Fermilab. The LHC offers the possibility to perform direct searches for new particles, and the neutrino is known to have properties, such as mass, that extend beyond the Standard Model and are so far the only evidence for new physics. A combination of these research topics enhances the possibilities to find answers to the fundamental open questions in particle physics and the chance for fundamental discoveries. With the ATLAS experiment at the LHC, we will continue to conduct searches for supersymmetric particles, which could resolve open questions related to the large difference between the electroweak energy scale and the GUT or the Planck scales (hierarchy problem), the asymmetry between matter and anti-matter, or the existence of a candidate for the dark matter. Overall 150 fb-1 of integrated luminosity at 13 TeV center of mass energy were collected, considerably extending the reach for discoveries of new particles. This project will analyze this full dataset, targeting searches in events with b-quark jets in more challenging channels to extend the phase space coverage for searches as much as possible. Furthermore, we are preparing the ATLAS detector upgrades for the HL-LHC. We will complete the design and testing phase of the high-speed data readout with optical fibers for the new pixel detector, which the University of Bern is responsible for. This is the tracker at the center of ATLAS with the finest granularity. The final construction of the system will start by the end of 2021, just at the completion of this project. For the DUNE experiment we aim at physics studies related to the near detector (ND). In particular, we will work on the understanding of physics of exclusive event topologies in neutrino interactions to put constraints on the cross sections in a combined analysis with the measurements at the far detector (FD). This is necessary for the precision measurements in DUNE to address questions, such as the neutrino mass-eigenstate hierarchy and the extent of the CP violation for neutrinos, besides possibly unveiling undiscovered new physics. The University of Bern is leading the effort for the liquid argon component at the ND and has initiated funding commitments from Switzerland for the ND and signed collaboration contracts with the US DOE and Fermilab. Liquid argon TPCs are the most powerful tracking devices for neutrino physics. In perspective, both the upgrade of the LHC to the HL-LHC and the DUNE program are considered flagship science projects in the field of high energy physics worldwide and are also the pillars of the particle physics program in Switzerland as defined by CHIPP. The same methods for high-level data analysis, statistical interpretation of physics results, high performance computing for data distribution and analysis, high speed detector readout and the reconstruction and event selection for very complex topologies will be used for both topics. This project will offer unique thesis opportunities and research topics at the forefront of science for three PhD students and two PostDocs.
