cutflow
Cutflow refers to a sequential application of selection criteria, known as cuts, to a dataset. This process is commonly employed in particle physics and data analysis to isolate specific events or data points of interest from a larger, more general dataset. Each cut progressively reduces the number of events that satisfy the preceding conditions, thereby refining the sample.
The purpose of a cutflow is to enhance the signal-to-background ratio. By applying cuts based on observable
A typical cutflow is documented step-by-step, showing the number of events remaining after each cut is applied.
The final sample, after all cuts have been applied, is then used for further analysis, such as
