We describe here the general mathematical approach to constructing likelihoods for fitting observed spectra in one or more dimensions with multiple sources, including the effects of systematic uncertainties represented as nuisance parameters, when the likelihood is to be maximized with respect to these parameters. We consider three types of nuisance parameters: simple multiplicative factors, source spectra "morphing" parameters, and parameters representing statistical uncertainties in the…

Within the framework of likelihood-based statistical tests for particle physics measurements, we derive expressions for estimating the statistical significance of discovery using the asymptotic
Untersuchung von Eigenschaften des Top-Quarks unter Benutzung eines Profile-Likelihood-Fits bei ATLAS Studies of Top Quark Properties Using a Profile Likelihood Fit at ATLAS
Top quarks play an essential role in the field of elementary particle physics especially due to their remarkable properties comprising a large mass, which is approximately comparable to the mass of a
The evaluation of the systematic uncertainties for the finite MC samples in the presence of negative weights
TLDR
This work proposes the method of incorporating the systematic uncertainties due to finite statistics of MC samples with negative weights, and the possible approximations are discussed and the comparison of different methods are presented.
Lectures on Statistics in Theory: Prelude to Statistics in Practice.
This is a writeup of lectures on "statistics" that have evolved from the 2009 Hadron Collider Physics Summer School at CERN to the forthcoming 2018 school at Fermilab. The emphasis is on foundations,
Statistical Learning and Inference at Particle Collider Experiments
TLDR
A large part of this document is devoted to a broad redefinition of the relevant concepts for problems in experimental particle physics to better connect these issues with those in other fields of research, so the solutions found can be repurposed.
Simultaneously determining the W ± boson mass and p T spectrum
We explore the possibility of simultaneously determining the W boson mass, mW, and QCD-related nuisance parameters that affect the W boson pT spectrum from a fit to the pT spectrum of the muon in the
submitter : Search for new physics in pp collision events with one electron and missing transverse energy using CMS data
In this thesis, a search for new physics in the electron + missing transverse energy channel is presented based on proton-proton collisions measured with the CMS detector at the LHC. The whole 2012
A search for new phenomena in pp collisions at √ s = 13 TeV in final states with missing transverse momentum and at least one jet using the α T variable CMS
A search for new phenomena is performed in final states containing one or more jets and an imbalance in transverse momentum in pp collisions at a centre-of-mass energy of 13 TeV. The analysed data
