Supersymmetric and non-supersymmetric models without catastrophic Goldstone bosons [PDF]

, 2017
The calculation of the Higgs mass in general renormalisable field theories has been plagued by the so-called "Goldstone Boson Catastrophe", where light (would-be) Goldstone bosons give infra-red divergent loop integrals.

Precise predictions for V + 2 jet backgrounds in searches for invisible Higgs decays

Journal of High Energy Physics, 2023
We present next-to-leading order QCD and electroweak (EW) theory predictions for V + 2 jet production, with V = Z, W ± , considering both the QCD and EW production modes and their interference.

Automation of NLO QCD and EW corrections with Sherpa and Recola [PDF]

, 2017
This publication presents the combination of the one-loop matrix-element generator Recola with the multipurpose Monte Carlo program Sherpa. Since both programs are highly automated, the resulting Sherpa+Recola framework allows for the computation of -in ...

Complete SMEFT predictions for four top quark production at hadron colliders

Journal of High Energy Physics, 2022
We study four top quark production at hadron colliders in the Standard Model Effective Field Theory (SMEFT). We perform an analysis at the tree-level, including all possible QCD- and EW-coupling orders and relevant dimension-six operators.

Renormalon contributions to \delta\rho

, 1995
Leading QCD vacuum polarization contributions to the electroweak parameter $\delta\rho$ are evaluated numerically using several different prescriptions for the gluon self-energy. Simple theoretical estimates of the asymptotic behavior are given.

Mixed NNLO QCD × electroweak corrections to single-Z production in pole approximation: differential distributions and forward-backward asymmetry

Journal of High Energy Physics
Radiative corrections in pole approximation, which are based on the leading contribution in a systematic expansion of amplitudes about resonance poles, naturally decompose into factorizable corrections attributed to the production or decay of the ...

Two-loop mixed QCD-EW corrections to q q ¯ $$ q\overline{q} $$ → Hg, qg → Hq, and q ¯ g $$ \overline{q}g $$ → H q ¯ $$ H\overline{q} $$

Journal of High Energy Physics, 2022
We compute the two-loop mixed QCD-Electroweak corrections to q q ¯ $$ q\overline{q} $$ → Hg and its crossed channels qg → Hq, q ¯ g $$ \overline{q}g $$ → H q ¯ $$ H\overline{q} $$ , limiting ourselves to the contribution of light virtual quarks.

Holomorphic field theories and higher algebra

Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Electroweak corrections to τ + τ − production in ultraperipheral heavy-ion collisions at the LHC

Journal of High Energy Physics
While the anomalous magnetic moments of the electron and the muon have been measured with remarkable precision, the magnetic moment of the τ-lepton is only known to rather limited precision.
