Abstract

Collider-based particle physics at the high energy frontier probes the most fundamental questions of the Universe in controlled laboratory settings. In the lab settings the initial states are known, allowing for a rigorous reconstruction of the elementary particle processes at a scale of 10^-19m. CERN's Large Hadron Collider (LHC) provide unique capabilities to study the recently discovered Higgs particle and search for new elementary particles that could for eg. constitute the dark matter of the universe. The computing resources applied for in this proposal will be used in the context of a research collaboration between KTH, Lund University (2 research groups), Stockholm University and Uppsala University on the subject of precision Higgs physics and search for new particles at the high energy frontier. Our research collaboration exploits synergies among the 5 swedish research groups working with LHC. The goal is to pool resources and expertise for increased impact, and enhanced scientific environment. In this spirit we aim at using the same computing platform. If funded, the project described in this application will enable: * common computing platform for the 5 Swedish LHC research groups, * very fast turn-around 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. It will allow the LHC research groups mentioned above to compete with these international groups.
