Collider-based particle physics at the high-energy frontier probes the most fundamental questions of the Universe in controlled laboratory settings. In the lab the initial states are known, allowing for rigorous reconstruction of the elementary particle processes at a scale of 10^-19 m. CERN's Large Hadron Collider (LHC) provides unique capabilities to study the recently discovered Higgs particle and search for new elementary particles that could for example constitute the dark matter of the universe. The computing resources this proposal seeks will be used in the context of a research collaboration between KTH, Lund University (two research groups), Stockholm University and Uppsala University on the subject of precision Higgs physics and searches for new particles at the high-energy frontier. Our research collaboration exploits synergies among the five Swedish research groups working with the LHC. The goal is to pool the resources and expertise for to increase the impact of our research, and to create an enhanced environment for our scientific computing needs. Since the needs for the various research topics within the collaboration are similar, we want to use the same computing platform. If funded, the project described in this application will enable: * common computing platform for the five Swedish LHC research groups * dramatically improved turn-around time of the data analyses of the 2016 and 2017 ATLAS data The processing stage that we want to speed up is specific to the particular researchers performing the data analysis and is not in common with members of the LHC collaborations outside Sweden. The processing task to be performed at the computing facility is a task performed by the local Swedish researchers and is a small task compared to what is performed daily by the LHC grid. However it does still require substantial computing resources beyond what is usually locally available at the Swedish universities. Many of the renowned universities world-wide that are involved in the LHC experiments have acquired capabilities that are comparable to what we are applying for in this SNIC funding application. A successful application will allow the LHC research groups in Sweden to compete with these international groups.
