abstract
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". The effect can be quantified in terms of a trial factor, which is the ratio between the probability of observing the excess at some fixed mass point, to the probability of observing it anywhere in the range. We propose a simple and fast procedure for estimating the trial factor, based on earlier results by Davies. We show that asymptotically, the trial factor grows linearly with the (fixed mass) significance.

Introduces Gaussian Process eigenmodes to unify statistical and systematic template uncertainties, replacing per-bin factors with truncated leading modes while containing Barlow-Beeston as a limiting case.
Asymptotic distributions of profiled likelihood-ratio test statistics are derived for new-physics searches and parameter estimation, with the Asimov dataset supplying a direct route to median experimental sensitivity.
Antineutrino-based detection can function as a barrier for locating nuclear submarines, with a 20 kt detector achieving Z_A ≈ 2.54 in the Strait of Gibraltar for a 100 MW case and higher scores with multiple detectors.
No excess in VVV production; bounds set on c_W/Λ² (-0.13 to 0.12 TeV^{-2}) and c_Hq3/Λ² (-0.24 to 0.21 TeV^{-2}) at 95% CL.
CMS reports fiducial and differential ttγ cross sections plus ttγ/tt ratios at 13 TeV that agree with Standard Model expectations within uncertainties.
Develops a likelihood ratio framework for assessing highly motivated subdominant new physics signals against experimental residuals that appear consistent with background predictions.
