Quantum entanglement is quantum: ZZ production at the LHC

Journal of High Energy Physics
Polarization and spin correlations in diboson systems serve as powerful tools for precision tests and searches for new physics. Recently, interpreting these observables through the lens of quantum information, for instance by examining whether the ...

Two-loop light-quark Electroweak corrections to Higgs boson pair production in gluon fusion

Journal of High Energy Physics
We compute two-loop electroweak corrections to double Higgs boson production in gluon fusion mediated by light quarks in a fully analytical way. We determine a basis of master integrals satisfying canonical differential equations in dlog form, enhanced ...

Theoretical results for electroweak-boson and single-top production

, 2015
I present results from recent high-order calculations for the production of electroweak bosons and top quarks. In particular, I discuss $W$ and $Z$ boson production at large transverse momentum, single-top production, and FCNC top production. Theoretical

Polarized NLO EW e+e- cross section calculations with ReneSANCe-v1.0.0

, 2020
In this paper we present a new Monte Carlo event generator ReneSANCe for simulation of processes at electron–positron colliders. In the current release of the generator the Bhabha scattering (e+e- -> e-e+) and Higgs-strahlung (e+e- -> ZH) process are ...

Electron-positron annihilation into heavy leptons at two loops

Journal of High Energy Physics
We calculate the NNLO QED corrections to the C-even part of differential cross section of e + e − → μ + μ − process. We neglect power corrections in the electron mass and obtain the result in terms of Goncharov’s polylogarithms.

Mixed QCD-EW corrections to W-pair production at electron-positron colliders

Journal of High Energy Physics
The discrepancy between the CDF measurement and the Standard Model theoretical prediction for the W-boson mass underscores the importance of conducting high-precision studies on the W boson, which is one of the predominant objectives of proposed future e

Unitarity-based techniques for one-loop calculations in QCD

, 1996
Perturbative QCD, and jet physics in particular, have matured sufficiently that rather than being merely subjects of experimental studies, they are now tools in the search for new physics. This role can be seen in the search for the top quark, as well as

EVAluation of the Equivalent Vector boson Approximation at highest energy colliders

Journal of High Energy Physics
Collider processes at the highest available partonic center-of-mass energies — 10 TeV and above — exhibit a new regime of electroweak interactions where electroweak gauge bosons mostly act as quasi-massless partons in vector boson fusion processes.

Fermionic electroweak two-loop corrections to Drell-Yan and related processes

Journal of High Energy Physics
We perform a complete calculation of the next-to-next-to-leading order (NNLO) electroweak fermionic corrections to fermion-pair production processes, where “fermionic” refers to contributions with closed fermion loops.
