HiggsBounds-5: testing Higgs sectors in the LHC 13 TeV Era [PDF]

open access: yesThe European Physical Journal C, 2020
We describe recent developments of the public computer code HiggsBounds. In particular, these include the incorporation of LHC Higgs search results from Run 2 at a center-of-mass energy of 13 TeV, and an updated and extended framework for the theoretical

Scattering amplitudes and electromagnetic horizons

open access: yesJournal of High Energy Physics, 2023
We consider the scattering of charged particles on particular electromagnetic fields which have properties analogous to gravitational horizons. Classically, particles become causally excluded from regions of spacetime beyond a null surface which we ...

Higgs in space! [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2010
We consider the possibility that the Higgs can be produced in dark matter annihilations, appearing as a line in the spectrum of gamma rays at an energy determined by the masses of the WIMP and the Higgs itself. We argue that this phenomenon occurs generally in models in which the the dark sector has large couplings to the most massive states of the SM ...

Deuteron uncertainties in the determination of proton PDFs

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We evaluate the uncertainties due to nuclear effects in global fits of proton parton distribution functions (PDFs) that utilise deep-inelastic scattering and Drell–Yan data on deuterium targets.

Theory and phenomenology of two-Higgs-doublet models [PDF]

open access: yes, 2011
We discuss theoretical and phenomenological aspects of two-Higgs-doublet extensions of the Standard Model. In general, these extensions have scalar mediated flavour changing neutral currents which are strongly constrained by experiment.

LHC: Standard Higgs and hidden Higgs [PDF]

open access: yesPhysics Letters B, 2012
Interpretations of Higgs searches critically involve production cross sections and decay probabilities for different analysis channels. Mixing effects can reduce production rates, while invisible decays can reduce decay probabilities. Both effects can transparently be quantified in Higgs systems where a visible Higgs boson is mixed with a hidden sector

A measurement of the Higgs boson mass in the diphoton decay channel [PDF]

open access: yes, 2020
A measurement of the mass of the Higgs boson in the diphoton decay channel is presented. This analysis is based on 35.9 fb$^{-1}$ of proton-proton collision data collected during the 2016 LHC running period, with the CMS detector at a center-of-mass ...

Pole-skipping of gravitational waves in the backgrounds of four-dimensional massive black holes

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Pole-skipping is a property of gravitational waves dictated by their behaviour at horizons of black holes. It stems from the inability to unambiguously impose ingoing boundary conditions at the horizon at an infinite discrete set of Fourier modes.

Measurements of the Higgs boson production and decay rates and constraints on its couplings from a combined ATLAS and CMS analysis of the LHC pp collision data at √s = 7 and 8 TeV [PDF]

open access: yes, 2016
Combined ATLAS and CMS measurements of the Higgs boson production and decay rates, as well as constraints on its couplings to vector bosons and fermions, are presented.

Observation of Higgs Boson Decay to Bottom Quarks. [PDF]

open access: yesPhysical Review Letters, 2018
The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for ...
