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 ...

Mixed QCD-EW corrections to the neutral-current Drell-Yan process
Journal of High Energy PhysicsWe report on the complete computation of the mixed QCD-electroweak corrections to the neutral-current Drell-Yan process. Our calculation holds in the entire range of dilepton invariant masses.

Three-loop master integrals for the Higgs boson self-energy with internal top-quarks and W-bosons
Journal of High Energy Physics, 2022 We consider the full set of master integrals with internal top-and W-propagators contributing to the three-loop Higgs self-energy diagrams of order O $$ \mathcal{O} $$ (α 2 α s ).

Higher-order supersymmetric contributions to electroweak precision observables [PDF]
, 2005 The dominant electroweak two-loop corrections to the precision observables M(_w) and sin(^2) θ off are calculated in the MSSM. They are obtained by evaluating the two loop Yukawa contributions of ϭ (aas) and ϭ (at2), ϭ (a2ab), ϭ (a2b), to the quantity Ap.

Feynman-diagram evaluation in the electroweak theory with computer algebra
, 2001 The evaluation of quantum corrections in the theory of the electroweak and strong interactions via higher-order Feynman diagrams requires complicated and laborious calculations, which however can be structured in a strictly algorithmic way.

Annalen der Physik, Volume 537, Issue 9, September 2025.Applications of the Dressing Field Method are reviewed and further expanded to the very foundations of the supersymmetric framework, where it allows to build relational supersymmetric field theory. Furthermore, a novel approach is proposed giving a unified description of fermionic matter fields and bosonic gauge fields: a Matter‐Interaction ...

Master integrals for O $$ \mathcal{O} $$ (αα s ) corrections to H → ZZ *
Journal of High Energy Physics, 2022 We present analytic results for all the Feynman integrals relevant for O $$ \mathcal{O} $$ (αα s ) virtual corrections to H → ZZ * decay. We use the method of differential equations to solve the master integrals while keeping the full dependence on the ...

Two loop vertices and tree level multicollinear limits in QCD [PDF]
, 2005 We present a summary of the methods required to solve loop-integrals and their reduction to Master Integrals. We then present the expansion in d = 4 - 2e of the Master Integrals required for the two loop massless vertex diagrams with three off-shell legs.
