Signal How1 #722775 In particle physics, a signal refers to the set of data or observations that indicate the presence or occurrence of the phenomenon under study, in contrast to the background noise, which encompasses similar characteristics but stemming from other phenomena.

Data Analysis »Data AnalysisData Analysis☜In the physics of the infinitely small, the study of a dataset recorded by a detector and the use of the provided information to search for a specific phenomenon, e.g. the decay of a particle into two others. If the phenomenon is observed, the analysis consists in measuring its properties with the highest precision. Most often, analysis results are published in an international scientific journal, along with a detailed report on the methods used to achieve them.☜9FDDBE

Measurement »MeasurementMeasurement☜Measurement is essential in physics, as this science constantly draws on comparisons between observations and models. However, absolute accuracy cannot be achieved: repeated measurements will fluctuate due to various environmental and instrinsic factors, linked to the measuring method. In addition, most phenomena studied in particle physics are random in nature: the same measurement has to be repeated many times to obtain an overall, statistical understanding of the phenomenon.☜D3ABAB
