  One way of searching through vast amounts of data that are already in, i.e. those that the detector has already delivered, is to look for occurrences that remain robust under varying conditions of detection. Physicists employ the technique of data cuts in such analysis. They cut out data that may be unreliable—when, for instance, a data set may be an artefact rather than a genuine particle interaction the experimenters expect. E.g. a colliding beam may interact with the walls of the detector and not with the other colliding beam, while producing a signal identical to the signal the experimenters expected the beam-beam interaction to produce. Thus, if under various data cuts a result remains stable, then it is increasingly likely to be correct and to represent the genuine phenomenon the physicists think it represents. The robustness of the result under various data cuts minimizes the possibility that the detected phenomenon only mimics the genuine one (Franklin 2013, 224–5).
