Look-elsewhere effect
Web27 de jul. de 2024 · The look-elsewhere effect is prominent throughout (astro)particle physics and cosmology. One of the most commonly known occurrences is in collider searches for new particles, for example it was a key consideration in the Higgs boson discovery [1, 8].In this example, one searches a large range of masses for a resonance, … WebThe look elsewhere effect is a cognitive bias that occurs when people find seemingly significant patterns or results in data by chance, due to the large number of …

Web11 de mai. de 2010 · Trial factors for the look elsewhere effect in high energy physics. When searching for a new resonance somewhere in a possible mass range, the significance of observing a local excess of events must take into account the probability of observing such an excess anywhere in the range. This is the so called “look elsewhere effect”.
