Methods for comparing two hypotheses
L. Lyons · 2009
In attempts to discover exciting new phenomena, it is useful to compare our data with (at least) two different hypotheses. These are H0, the null hypothesis, corresponding to just known physics and nothing new; and H1, a specific version of new physics, perhaps involving free parameters, such as the mass of a new particle. Methods of performing this comparison, with a view to claiming a discovery, are reviewed. 1
