The experimental high-energy physics processes are a brilliant case of application of the rules and methodologies of statistics. It comprises of multitude of processes each having a unique topography and physical kinematics. Some of the processes are called the signal for their specific treatment for extraction of a physical quantity. The other processes are mainly categorized as a bunch of background processes each contaminating the signal processes. The signals and background processes can crossfeed each other in the measurement of the yield for each of the process. There are errors associated with yield measurements and these propagate through the estimation of the yield and the efficiencies of the cross-feed associated with each yield [signal and background].
