Panagiotis Spentzouris Jim Kowalkowski Panagiotis Spentzouris and Jim Kowalkowski, head and deputy head of the Accelerator and Detector Simulation and Support Department, wrote this column. To collect data and perform a typical physics analysis in today’s high-energy physics experiments requires a wide range of computational tools as well as specialized techniques and algorithms. The analysis goal is to measure fundamental physical quantities and compare them to theoretical models. Raw event data must be filtered, stored and then processed using…
