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.

IceCube data analysis yields a 3.1 sigma excess consistent with dark matter annihilation into neutrinos from the dwarf galaxy Bootes III at 26.5 TeV mass.
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.
Correlated HNL discovery at SHiP and flavor ratio shifts in astrophysical neutrinos at telescopes would establish neutrinos as Majorana fermions.
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.
Null result from dimuon scouting search at 13.6 TeV sets 95% CL limits on long-lived particle production in Higgs and b-hadron decay channels across multiple BSM models.
A reweighting method creates model-agnostic likelihoods from histogram analyses, applied to Belle II B+ to K+ nu nubar data for WET constraints and light new physics searches.
The paper presents a simple conservative relation between local and global significances that accounts for look-elsewhere effects across multiple invariant-mass distributions at the LHC.
No significant excess observed in CMS four-lepton data; 95% CL upper limits set on heavy scalar resonance production cross section times BR(ZZ) ranging 0.05-0.1 pb at low mass to 0 pb at high mass.
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.
