Lay Summary (German)

Lead
Das vorliegende SNF-SCOPES Projekt stellt eine Zusammenarbeit dar von Instituten in Serbien (Belgrad), Ungarn (Budapest und Debrecen) und der Schweiz (ETH Zurich). Die TeilnehmerInnen an diesem Projekt forschen aktiv in der Hochenergiephysik und befassen sich speziell mit Fragen, wie sie mit dem CMS Experiment am Large Hadron Collider (LHC) am CERN beantwortet werden können. Neben wichtigen Beiträgen zur Datenanalyse sind auch Beiträge zur Verbesserung von Detektorkomponenten geplant, sowie die Erstellung neuer theoretischer Vorhersage für zu messende Prozesse am LHC.
Lay summary

Das CMS Experiment ist eines der Gross-Experimente am LHC Beschleuniger des CERN. Im Jahre 2015 wird der Beschleuniger nach einer aktuellen Instandhaltungsphase wieder in Betrieb genommen werden, bei einer noch nie erreichten Energie. Die Analyse dieser neuen Daten verspricht viele neue Erkenntnisse zu erlangen und ermöglicht, z.B., die Eigenschaften des neu entdeckten Higgs Bosons genauer zu vermessen, oder nach neuen Teilchen zu suchen.

Das vorliegende Projekt vereint PhysikerInnen aus Serbien, Ungarn und der Schweiz, welche alle im CMS Experiment involviert sind, bzw. theoretische Vorhersagen für die zu messenden Prozesse am LHC machen. Diese Gruppen haben bereits in einem Vorgänger-SCOPES-Projekt sehr erfolgreich zusammengearbeitet. Konkret sind die Gruppen der ETH und aus Belgrad hauptverantwortlich für das Detektor-Kontrollsystem des elektromagnetischen Kalorimeters des CMS Experimentes, und werden wichtige Instandhaltungsarbeiten am System durchführen, bevor es dann ab 2015 wieder routinemässig in Betrieb sein wird. Die Gruppen aus Ungarn werden sich vor allem wieder führend an der Analyse von Daten aus Schwerionenkollisionen beteiligen, sowie wiederum ihre Expertise zur Spurenrekonstruktion einbringen. Die Gruppe aus Debrecen ist spezialisiert auf theoretische Vorhersagen von komplizierten Prozessen, die speziell die schweren Top-Quarks enthalten.

Die Finanzierung durch SCOPES wird es ermöglichen, dass Forscher aus Ungarn und Serbien häufig ans CERN zu Forschungsaufenthalten kommen. Gerade in grossen Kollaborationen wie CMS ist es enorm wichtig, sich aktiv am Betrieb des Experimentes und an den Sitzungen der Kollaboration am CERN beteiligen zu können. Dies gibt den Gruppen deutlich mehr Sichtbarkeit, was auch für deren wissenschaftlichen Nachwuchs von grosser Wichtigkeit ist.

Abstract

The Institute for Particle Physics (IPP) of ETH Zurich is one of the leading Institutes participating in the Compact Muon Solenoid (CMS) experiment at CERN’s Large Hadron Collider (LHC). After a most successful first running period in 2009-2012, CMS is presently in the shutdown and maintenance phase (years 2013 and 2014), in view of the planned LHC re-start in spring 2015. The design concept of the CMS experiment guarantees full exploitation of the physics potential offered by the LHC, which will provide proton-proton collisions at unprecedented centre-of-mass energies of 13 - 14 TeV in the years 2015 and later. CMS has thus a unique prospective for fur-ther important discoveries in Elementary Particle Physics for the next decade, after the celebrated breakthrough in 2012 with the discovery of the long-sought Higgs boson. Two of the most distinctive and important detector systems of the CMS experiment are the high precision Electromagnetic Calorimeter (ECAL), consisting of about 76000 Lead-Tungstate crystals, and the muon spectrometer. These systems are crucial for a large spectrum of measurements and their good performance is essential for the success of the CMS experiment. Most notably, these systems have been essential for the discovery of the Higgs boson in 2012. From the very beginning the IPP had major responsibility of scientific, technical and managerial nature for this ECAL sub-detector. In particular, we carry the project leadership for the development, construction and operation of the Detector Control System (DCS) of ECAL. This project is realized in collaboration with scientists from the VINCA Institute and the Faculty of Physics of the University of Belgrade (Serbia). Similarly, Hungarian Institutes from Budapest and Debrecen have taken important responsibilities for the alignment system of the muon spectrometer.This proposal for a Joint Research Project (JRP) is intended to strengthen the already existing and very successful collaboration with our colleagues from Serbia and Hungary, which manifested itself also in the successful execution of a previous SCOPES JRP, Project Number IZ73Z0_128079. The proposal for a new (follow-up) JRP is motivated by the success of the previous JRP, exemplified by a considerable number of highly important publications in the context of the CMS experiment, and, very importantly, by the fact that some of our youngest colleagues in the JRP, from Serbia and Hungary, have obtained several prestigious Postdoc positions (MIT, CERN). This would not have been possible without the support by the SCOPES programme, which allowed them to obtain significant visibility at CERN in the day-to-day operations and meetings of the CMS experiment. The proposed cluster of institutes would again build on a large expertise on various important aspects of the CMS experiment and thus again play a competitive role in the upcoming data analyses in 2015 and beyond.The requested funds are intended to allow the Eastern European partners to spend a considerable amount of time at CERN, both to participate in the operation and maintenance of the detector components mentioned above and to actively take part in the physics and analysis discussions of the collaboration. For smaller institutes such as those from Serbia and Hungary it is difficult to gain visibility in a very large collaboration like CMS (close to 3000 scientists from about 180 In-stitutes). Therefore it is important for them to have a strong presence at CERN and a close collaboration with larger institutes such as the IPP of ETH Zurich. Again, the logic behind this reasoning was proven to be correct during the previous JRP, which has led to the successes briefly mentioned above and described in detail in the final scientific report to the SNF for the previous JRP.The proposed research topics concern (i) the operation and maintenance of the ECAL safety and humidity readout systems, which is part of the ECAL DCS, and the muon alignment system; (ii) the participation in a number of different CMS data analyses, in particular regarding the efforts of studying the newly found Higgs boson, as well as exploring phenomena of strong interactions, quark and gluon matter; and (iii) contributions to phenomenology of LHC physics by higher-order quantum chromo-dynamics (QCD) calculations. The objectives and expected results of the proposed JRP can thus be summarized as follows:? Allow for prolonged stays of members from the Serbian and Hungarian research teams at CERN in order to carry out the following research activities: • Operation and maintenance of the CMS ECAL safety and humidity readout systems and the muon alignment system; • Participation in the final commissioning of the CMS detector in 2014 and the start-up of the 13 TeV physics run in 2015; • Setting up and participation in physics analyses of LHC data, which concentrate on the exploitation of the excellent capabilities of the CMS sub-detectors; • Support of the data analysis activities in terms of theoretical contributions, most notably in the jet and heavy quark pair hadroproduction sector of strong interactions.? These activities should result in • highly efficient and safe operation of the CMS ECAL and precise muon track reconstruction thanks to an optimally aligned muon system; • an in-depth understanding of the upcoming high-energy CMS data; • first physics results from the analyses of the data collected during the initial years of the next LHC running.Based on the positive experience from the past SCOPES JRP, we are convinced that the strong and visible participation of the Eastern European partners in a fore-front international research project such as the CMS experiment will allow them to (a) further strengthen their scientific capabilities, (b) improve the efficiency of their work and participation within large international collaborations, (c) enhance their national as well as international reputation and thus (d) to attract students, funding agencies and industries in their home countries, with evident long-term benefits.
