Complementary Probes of the Dimension‐6 Operator via Gravitational Waves and Multi‐Higgs Production

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
We investigate the phenomenological consequences of a dimension‐6 operator H†H3/Λ2, Λ is the effective scale at which new physics takes over, which modifies the scalar potential of the standard model and can induce a strong first‐order electroweak phase transition (SFOEWPT). We estimate the lower limit on the effective scale Λ to be 515 GeV from the di‐

O α s 2 α $$ \mathcal{O}\left({\alpha}_s^2\alpha \right) $$ corrections to quark form factor

Journal of High Energy Physics
We present the analytic results for the non-singlet contributions to the three-loop mixed strong-electroweak O α s 2 α $$ \mathcal{O}\left({\alpha}_s^2\alpha \right) $$ virtual corrections to the quark form factors.

Unification of Conformal and Fuzzy Gravities With Internal Interactions Resulting in SO(10) and a Possible Probe Through Stochastic Gravitational Wave Background

Fortschritte der Physik, Volume 73, Issue 9-10, October 2025.
Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

Mixed QCD-EW corrections to the neutral-current Drell-Yan process

Journal of High Energy Physics
We 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.

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 ...

Two-loop mixed QCD-EW corrections to charged current Drell-Yan

Journal of High Energy Physics
We present the two-loop mixed strong-electroweak virtual corrections to the charged current Drell-Yan process. The final-state collinear singularities are regularised by the lepton mass.

Relational Supersymmetry via the Dressing Field Method and Matter‐Interaction Supergeometric Framework

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 ...

A procedure g5anchor to anchor γ 5 in Feynman diagrams for the Standard Model

Journal of High Energy Physics
We present a procedure g5anchor to anchor γ 5 in the definition of a Dirac trace with γ 5 in Dimensional Regularization (DR) in Feynman diagrams for the Standard Model, based on a recent revision of the works by Kreimer, Gottlieb and Donohue.

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.

Two-loop mixed QCD-electroweak amplitudes for Z+jet production at the LHC: bosonic corrections

Journal of High Energy Physics
We present a calculation of the bosonic contribution to the two-loop mixed QCD-electroweak scattering amplitudes for Z-boson production in association with one hard jet at hadron colliders.
