The decay constants f D and fDs $$ {f}_{D_s} $$ in the continuum limit of N f = 2 + 1 domain wall lattice QCD

open access: yesJournal of High Energy Physics, 2017
We present results for the decay constants of the D and D s mesons computed in lattice QCD with N f = 2 + 1 dynamical flavours. The simulations are based on RBC/UKQCD’s domain wall ensembles with both physical and unphysical light-quark masses and ...

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 ...

Isospin mass differences of the B, D and K

open access: yesJournal 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 ...

Measurement of Higgs boson production and properties in the WW decay channel with leptonic final states [PDF]

open access: yes, 2013
A search for the standard model Higgs boson decaying to a W-boson pair at the LHC is reported. The event sample corresponds to an integrated luminosity of 4.9 fb−1 and 19.4 fb−1 collected with the CMS detector in pp collisions at s√ = 7 and 8 TeV ...

Relating amplitude and PDF factorisation through Wilson-line geometries

open access: yesJournal of High Energy Physics, 2019
We study long-distance singularities governing different physical quantities involving massless partons in perturbative QCD by using factorisation in terms of Wilson-line correlators. By isolating the process-independent hard-collinear singularities from

Limits on neutral Higgs boson production in the forward region in pp collisions at s√=7 TeV [PDF]

open access: yes, 2013
Limits on the cross-section times branching fraction for neutral Higgs bosons, produced in pp collisions at TeX TeV, and decaying to two tau leptons with pseudorapidities between 2.0 and 4.5, are presented. The result is based on a dataset, corresponding

Renormalization of gluonic leading-twist operators in covariant gauges

open access: yesJournal 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.

Gauge invariant accounts of the Higgs mechanism [PDF]

open access: yes, 2011
The Higgs mechanism gives mass to Yang-Mills gauge bosons. According to the conventional wisdom, this happens through the spontaneous breaking of gauge symmetry.
