Like-sign W-boson scattering at the LHC — approximations and full next-to-leading-order predictions

Journal of High Energy Physics, 2023
We present a new calculation of next-to-leading-order corrections of the strong and electroweak interactions to like-sign W-boson scattering at the Large Hadron Collider, implemented in the Monte Carlo integrator Bonsay. The calculation includes leptonic

Broken electroweak phase at high temperature in the Littlest Higgs model with T-parity [PDF]

, 2009
We have examined in detail the nonrestoration of symmetry at high temperature in a finite-temperature Littlest Higgs model, without and with T-parity, by evaluating the one-loop-order finite-temperature integrals of the effective potential numerically ...

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 ...

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.

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.

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.

Multiple photon corrections to the neutral-current Drell-Yan process

, 2005
Precision studies of single W and Z production processes at hadron colliders require progress in the calculation of electroweak radiative corrections.

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 ...

Three loop master integrals for $$\mathcal{O}\left(\alpha {\alpha }_{s}^{2}\right)$$ corrections to quark form factor

Journal of High Energy Physics
We consider the three-loop mixed strong-electroweak $$\left(\mathcal{O}\left(\alpha {\alpha }_{s}^{2}\right)\right)$$ corrections to the quark form factor.

Next-to-leading order electroweak corrections to gg → HH and gg → gH in the large-m t limit

Journal of High Energy Physics, 2023
We compute two-loop electroweak corrections to Higgs boson pair and Higgs plus jet production, taking into account all sectors of the Standard Model. All diagrams with virtual top quarks are computed in an expansion for large top quark mass up to order 1/
