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

Composite Higgses [PDF]

open access: yes, 2014
We present an overview of composite Higgs models in light of the discovery of the Higgs boson. The small value of the physical Higgs mass suggests that the Higgs quartic is likely loop generated, thus models with tree-level quartics will generically be ...

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 ...

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.

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

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.

Minimal supersymmetric model of Higgs-Higgs condensation [PDF]

open access: yesPhysical Review D, 1995
The discussion of the following two topics are included, (1). How large can the lightest-Higgs mass be in the supersymmetric standard models? (2). The triviality bound of the Higgs mass, with the conclusion that the SUSY model of Higgs-Higgs condensation will be the most promising candidate if the lightest-Higgs mass of the MSSM is excluded by the ...

Measurements of Higgs boson properties in the diphoton decay channel with 36 fb$^{-1}$ of $pp$ collision data at $\sqrt{s} = 13$ TeV with the ATLAS detector [PDF]

open access: yes, 2018
Properties of the Higgs boson are measured in the two-photon final state using 36.1 fb$^{-1}$ of proton-proton collision data recorded at $\sqrt{s} = 13$ TeV by the ATLAS experiment at the Large Hadron Collider.
