Alternatives to an Elementary Higgs

, 2015
We review strongly coupled and extra dimensional models of electroweak symmetry breaking. Models examined include warped extra dimensions, bulk Higgs, "little" Higgs, dilaton Higgs, composite Higgs, twin Higgs, quantum critical Higgs, and "fat" SUSY ...

When is a Higgs THE Higgs?

, 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.

Updated global SMEFT fit to Higgs, diboson and electroweak data [PDF]

Journal of High Energy Physics, 2018
A bstractThe ATLAS and CMS collaborations have recently released significant new data on Higgs and diboson production in LHC Run 2. Measurements of Higgs properties have improved in many channels, while kinematic information for h → γγ and h → ZZ can now

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

Journal 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

Journal 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 ...

Isospin mass differences of the B, D and K

Journal of High Energy Physics, 2023
We compute the electromagnetic mass difference for the B-, D- and K-mesons using QCD sum rules with double dispersion relations. For the B- and D-mesons we also compute the linear quark mass correction, whereas for the K the standard soft theorems prove ...

Higgs Mixing in the NMSSM and Light Higgsinos

, 2014
We explore the effects of Higgs mixing in the general next-to-minimal supersymmetric Standard Model (NMSSM). Extended to include a gauge singlet, the Higgs sector can naturally explain the observed Higgs boson mass in TeV scale supersymmetry without ...

Renormalization of gluonic leading-twist operators in covariant gauges

Journal of High Energy Physics, 2022
We provide the all-loop structure of gauge-variant operators required for the renormalisation of Green’s functions with insertions of twist-two operators in Yang-Mills theory.
