Classical Yang-Mills observables from amplitudes
Journal 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 ...

Surprises from complete vector portal theories: New insights into the dark sector and its interplay with Higgs physics [PDF]
, 2017 We study UV complete theories where the Standard Model (SM) gauge group is extended with a new abelian $U(1)$, and the field content is augmented by an arbitrary number of scalar and fermion SM singlets, potentially including dark matter (DM) candidates.

Correlation of theoretical uncertainties in PDF fits and theoretical uncertainties in predictions
European Physical Journal C: Particles and Fields, 2021 We show how to account for correlations between theoretical uncertainties incorporated in parton distribution function (PDF) fits, and the theoretical uncertainties in the predictions made using these PDFs.

EPJ Web of Conferences, 2014 Searches for the Higgs boson at CMS, based on the data collected in 2011 and 2012 at 7 and 8 TeV centre-of-mass energy, corresponding to integrated luminosities of 5 and 20 fb−1, are presented. The observed new boson is found to be consistent with the Standard Model Higgs boson in all investigated properties such as the spin and couplings to bosons and

Nuclear uncertainties in the determination of proton PDFs
European 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.

Prospects for Higgs physics at energies up to 100 TeV [PDF]
Reports on progress in physics. Physical Society, 2015 We summarize the prospects for Higgs boson physics at future proton–proton colliders with centre of mass (c.m.) energies up to 100 TeV. We first provide the production cross sections for the Higgs boson of the Standard Model from 13 TeV to 100 TeV, in ...

Bayesian approach to inverse problems: an application to NNPDF closure testing
European Physical Journal C: Particles and Fields, 2022 We discuss the Bayesian approach to the solution of inverse problems and apply the formalism to analyse the closure tests performed by the NNPDF collaboration.

Directly probing the Higgs-top coupling at high scales
Physics Letters B, 2022 We explore the sensitivity to new physics for the coupling of the Higgs boson (h) and top quark (t) at high energy scales with the process pp→tt¯h at the high-luminosity LHC.

Journal 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 ...
