Web22 de jan. de 2012 · This circumstance is commonly termed in high energy physics applications as the look elsewhere effect. How it concretely manifests in a specific problem of signal search depends upon the particular strategy adopted to unravel the sought-after signal from the underlying background. In this respect an increasingly popular method is … Web3. The Look Elsewhere Effect. We now want to take a closer look at the first step of the data analysis described above. It deals with the question of whether or not the collected data imply new physics. Let us assume that physicists have calculated the background of the process under investiga-tion.
