class RooStats::HypoTestResult: public TNamed

HypoTestResult is an base class for a results from hypothesis tests. Any tool inheriting from HypoTestCalculator can return a HypoTestResult. As such, it stores a p-value for the null-hypothesis (eg. background-only) and an alternate hypothesis (eg. signal+background). The p-values can also be transformed into confidence levels (CLb, CLsplusb) in a trivial way. The ratio of the CLsplusb to CLb is often called CLs, and is considered useful, though it is not a probability. Finally, the p-value of the null can be transformed into a number of equivalent Gaussian sigma using the Significance method.
