Lay Summary (German)

Lead
Dieser Antrag fördert die Forschung am CMS (Compact Muon Solenoid) Experiment am CERN (European Organization for Nuclear Research), bei dem hochenergetische Proton-Proton-Kollisionen am LHC (Large Hadron Collider) untersucht werden.
Lay summary
This application supports research on CMS (Compact Muon Solenoid) experiment at CERN (European Organization for Nuclear Research), are examined in the high-energy proton-proton collisions at the LHC (Large Hadron Collider). The goal of our research is to gain a more comprehensive understanding of elementary particles and interactions. Specifically, we investigate the properties of the newly discovered Higgs boson and look for signs for the production of dark matter as well as for evidence of the existence of extra dimensions in the form of massive resonances. 
Our group analyzed the collision data, which were recorded in 2012, and prepares on possible discoveries in the year 2015, when the LHC starts up again with almost twice the energy. 
Moreover, we are involved in the operation of the CMS pixel detector. CMS pixel detector enables the precise reconstruction of the tracks, and vertices of the charged particles produced in the collisions. Among other things we are working on the calibration of the detector, the maintenance of the different hardware components as well as the development of software and simulations. We also contribute to the development of a new pixel detector system with better efficiency at high data rates. We are developing the electronics for data readout and communication with the detector, build a support structure for the electronics and a new, lightweight cooling system. The installation of the new pixel detector in the CMS experiment is planned for the year 2017.

Lay summary

This proposal supports research with the CMS (Compact Muon Solenoid) experiment at CERN (European Organization for Nuclear Research) which uses high energy proton collisions from the LHC (Large Hadron Collider).  Our goals are to provide a more complete understanding of the forces and particles of nature.  In particular we are studying the properties of the newly discovered Higgs boson, searching for evidence of dark matter particle production, and looking for extra dimensions by studying high mass resonances.  Our group is preparing analyses of 8 TeV collision data collected in 2012, and preparing for discoveries when the LHC starts in 2015 at almost twice the energy.   We are also engaged in the CMS precision tracking system (pixel detector) which accurately measures the trajectory and vertex position of charged particles created in collisions.  We participate in calibrations, hardware testing and replacement, developing software, and simulations.  We are also helping to construct a new, upgraded pixel detector with improved performance at high data rates.  We are preparing new electronics for readout and communication with the detector, and building a new light-weight cooling system, and supply support system, for installation in 2017.

Abstract

This proposal is for particle physics research using the CMS (Compact Muon Solenoid) experiment at the LHC (Large Hadron Collider) located at CERN (European Organization for Nuclear Research). Prof. Canelli's group will be searching for Higgs bosons produced in association with top quarks as well as for dark matter in association with third generation quarks, and studying matrix element analysis techniques. Prof. Kilminster's group will be involved in heavy resonance searches with jets that could arise in extra dimensional scenarios, boosted jets and substructure analysis techniques, and Standard Model (SM) and beyond-SM Hbb searches. We request funds for a crucial two year time period (October 2014-September 2016). Not only will we begin CMS data taking with almost double the energy, but we will also finish and install an upgrade of the pixel detector. In the first year of this grant, we will move from finishing our 8 TeV publications and prototyping of the pixel upgrade components, to preparing the detector, analysis techniques, and analyses for 13 TeV data. When the first 13 TeV data arrives in summer 2015, we will be positioned for some immediate discoveries with small datasets. In the second year we will be completing the phase I pixel upgrade which will be installed during the winter technical stop of 2016/17. Moreover, in the second year, we will harvest physics results from the 13 TeV data.
