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.

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.

Higgs physics at the Future Circular Collider [PDF]
, 2017 The unique Higgs physics opportunities accessible at the CERN Future Circular Collider (FCC) in electron-positron ($\sqrt{s}$ = 125, 240, 350 GeV) and proton-proton ($\sqrt{s}$ = 100 TeV) collisions, are succinctly summarized.

HiggsSignals-2: probing new physics with precision Higgs measurements in the LHC 13 TeV era [PDF]
The European Physical Journal C, 2020 The program HiggsSignals confronts the predictions of models with arbitrary Higgs sectors with the available Higgs signal rate and mass measurements, resulting in a likelihood estimate.

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 ...

Simplified models for Higgs physics: singlet scalar and vector-like quark phenomenology [PDF]
Journal of High Energy Physics, 2016 Simplified models provide a useful tool to conduct the search and exploration of physics beyond the Standard Model in a model-independent fashion. In this work we consider the complementarity of indirect searches for new physics in Higgs couplings and ...

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

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.

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.
