Regularising experimental correlations in LHC data: theory and application to a global analysis of parton distributions

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We show how an inaccurate determination of experimental uncertainty correlations in high-precision LHC measurements may undermine the reliability of the associated $$\chi ^2$$ χ 2 .

Observation of a new particle in the search for the Standard Model Higgs boson at the CMS detector [PDF]

open access: yes, 2013
The discovery of the Standard Model (SM) Higgs boson is one of the primary physics objectives of the Large Hadron Collider at CERN. This thesis describes a search carried out for the SM Higgs boson on data collected during the 2011 and 2012 proton ...

Reweighting a parton shower using a neural network: the final-state case

open access: yesJournal of High Energy Physics, 2019
The use of QCD calculations that include the resummation of soft-collinear logarithms via parton-shower algorithms is currently not possible in PDF fits due to the high computational cost of evaluating observables for each variation of the PDFs ...

Radiative decays of heavy-light mesons and the f H , H ∗ , H 1 T $$ {f}_{H,{H}^{\ast },{H}_1}^{(T)} $$ decay constants

open access: yesJournal of High Energy Physics, 2021
The on-shell matrix elements, or couplings g H H ∗ H 1 γ $$ {g}_{H{H}^{\ast}\left({H}_1\right)\upgamma} $$ , describing the B D q ∗ $$ B{(D)}_q^{\ast } $$ → B(D) q γ and B 1q → B q γ (q = u, d, s) radiative decays, are determined from light-cone sum ...

Measurements of properties of the Higgs boson decaying into the four-lepton final state in pp collisions at s=13$$ \sqrt{s}=13 $$ TeV [PDF]

open access: yes, 2017
A bstractProperties of the Higgs boson are measured in the H → ZZ → 4ℓ (ℓ = e, μ) decay channel. A data sample of proton-proton collisions at s=13$$ \sqrt{s}=13 $$ TeV, collected with the CMS detector at the LHC and corresponding to an integrated ...

Phase-resolved Higgs response in superconducting cuprates [PDF]

open access: yesNature Communications, 2019
In high-energy physics, the Higgs field couples to gauge bosons and fermions and gives mass to their elementary excitations. Experimentally, such couplings can be inferred from the decay product of the Higgs boson, i.e., the scalar (amplitude) excitation

When is a Higgs THE Higgs?

open access: yes, 1994
The one-Higgs-doublet standard model is necessarily incomplete because of the triviality of the scalar symmetry-breaking sector. If the Higgs mass is approximately 600 GeV or higher, there must be additional dynamics at a scale $Λ$ which is less than a few TeV.

Higgs Physics [PDF]

open access: yesNuclear and Particle Physics Proceedings, 2015
The cause of the screening of the weak interactions at long distances puzzled the high-energy community for more nearly half a century. With the discovery of the Higgs boson a new era started with direct experimental information on the physics behind the breaking of the electroweak symmetry.

Higgs Boson Studies at the Tevatron [PDF]

open access: yes, 2013
We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90--200 GeV$/c^2$ produced in the gluon-gluon fusion, $WH$, $ZH$, $t{\bar{t}}H$, and vector boson fusion processes, and decaying in the $H ...
