Charged and neutral B ¯ u , d , s $$ {\overline{B}}_{u,d,s} $$ → γ form factors from light cone sum rules at NLO

open access: yesJournal of High Energy Physics, 2021
We present the first analytic O α s $$ \mathcal{O}\left({\alpha}_s\right) $$ -computation at twist-1,2 of the B ¯ u , d , s $$ {\overline{B}}_{u,d,s} $$ → γ form factors within the framework of sum rules on the light-cone. These form factors describe the

Classical Yang-Mills observables from amplitudes

open access: yesJournal of High Energy Physics, 2020
The double copy suggests that the basis of the dynamics of general relativity is Yang-Mills theory. Motivated by the importance of the relativistic two-body problem, we study the classical dynamics of colour-charged particle scattering from the ...

Boomerang webs up to three-loop order

open access: yesJournal of High Energy Physics, 2021
Webs are sets of Feynman diagrams which manifest soft gluon exponentiation in gauge theory scattering amplitudes: individual webs contribute to the logarithm of the amplitude and their ultraviolet renormalization encodes its infrared structure.

First look at the physics case of TLEP [PDF]

open access: yes, 2013
The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV and with measured properties compatible with those of a Standard-Model Higgs boson, coupled with the absence of discoveries of phenomena beyond the Standard Model at ...

Philosophical perspectives on ad hoc-hypotheses and the Higgs mechanism [PDF]

open access: yes, 2013
We examine physicists' charge of adhocness against the Higgs mechanism in the Standard Model of elementary particle physics. We argue that even though this charge never rested on a clear-cut and well-entrenched definition of "ad hoc", it is based on ...

Nuclear uncertainties in the determination of proton PDFs

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We show how theoretical uncertainties due to nuclear effects may be incorporated into global fits of proton parton distribution functions (PDFs) that include deep-inelastic scattering and Drell–Yan data on nuclear targets.

HIGGS PHYSICS AND SUPERSYMMETRY [PDF]

open access: yesInternational Journal of Modern Physics A, 2012
A brief overview of Higgs physics and of supersymmetry is given. The central theme of the overview is to explore the implications of the recent discovery of a Higgs-like particle regarding the prospects for the discovery of supersymmetry assuming that it is indeed the spin-0 CP even boson that enters in the spontaneous breaking of the electroweak ...

Search for WH production with a light Higgs boson decaying to prompt electron-jets in proton–proton collisions at $\sqrt {s}=7$ TeV with the ATLAS detector [PDF]

open access: yes, 2013
A search is performed for WH production with a light Higgs boson decaying to hidden-sector particles resulting in clusters of collimated electrons, known as electron-jets.

Physics at a Higgs Factory [PDF]

open access: yesInternational Journal of Modern Physics A, 2016
I give an overview of the physics potential at possible future [Formula: see text] colliders, including the ILC, FCC-ee, and CEPC. The goal is to explain some of the measurements that can be done in the context of electroweak precision tests and Higgs couplings, to compare some of the options under consideration, and to put the measurements in context ...
