Since the discovery of the Higgs boson in 2012, particle physicists have not found any statistically significant deviations from the Standard Model. This has led to a shift of emphasis from model testing to exploration and an increasing popularity of ‘model-independent’ experimental approaches. Our goal is to analyze this shift by focusing on particle and event signatures. A differentiated picture of experimentation emerges between the extremes of theory guidance and theory-free exploration. Using the example of the top quark, we distinguish four types of motivations for the study of physics processes.
Our research is part of the research unit Epistemology of the LHC supported by the German Research Foundation DFG (project FOR 2063).
