Reviews of Modern Physics, 1999 “Gentlemen and Fellow Physicists of America: We meet today on an occasion which marks an epoch in the history of physics in America; may the future show that it also marks an epoch in the history of the science which this Society is organized to cultivate!” (Rowland, 1899).1 These are the opening words of the address by Henry Rowland, the first ...

Non-factorisable contribution to t-channel single-top production
Journal of High Energy Physics, 2022 We compute the non-factorisable O $$ \mathcal{O} $$ ( α s 2 $$ {\alpha}_s^2 $$ ) corrections to t-channel single-top quark production at the LHC. These peculiar corrections arise because of interactions between the heavy- and the light-quark lines and ...

Theoretical particle physics [PDF]
, 1992 We have carried out research in lattice gauge theory, superstring theory, supersymmetry, the solar neutrino puzzle, QCD perturbation theory, and phenomenological models of hadrons. In this report, we summarize our work in each of these areas.

Gapped Goldstones at the cut-off scale: a non-relativistic EFT
Journal of High Energy Physics, 2021 At finite density, the spontaneous breakdown of an internal non-Abelian symmetry dictates, along with gapless modes, modes whose gap is fixed by the algebra and proportional to the chemical potential: the gapped Goldstones.

On non-factorisable contributions to t-channel single-top production
Journal of High Energy Physics, 2021 We compute the non-factorisable contribution to the two-loop helicity amplitude for t-channel single-top production, the last missing piece of the two-loop virtual corrections to this process.

On phase-space integrals with Heaviside functions
Journal of High Energy Physics, 2022 We discuss peculiarities that arise in the computation of real-emission contributions to observables that contain Heaviside functions. A prominent example of such a case is the zero-jettiness soft function in SCET, whose calculation at next-to-next-to ...

Hyperfine splitting effects in string hadronization
European Physical Journal C: Particles and Fields, 2022 We revisit the recipe for hadron formation in the Lund string hadronization model. Given an incoming quark or quark-diquark pair, weights for hadron formation are updated to take hyperfine splitting effects arising from the mass difference between ...

Learning from radiation at a very high energy lepton collider
Journal of High Energy Physics, 2022 We study the potential of lepton collisions with about 10 TeV center of mass energy to probe Electroweak, Higgs and Top short-distance physics at the 100 TeV scale, pointing out the interplay with the long-distance (100 GeV) phenomenon of Electroweak ...

Journal of High Energy Physics, 2023 The renormalization-scale dependence of the non-factorizable virtual corrections to Higgs boson production in weak boson fusion at next-to-next-to-leading order in perturbative QCD is unusually strong, due to the peculiar nature of these corrections.
