The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post-War Period. [PDF]
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Two-loop tensor integral coefficients in OpenLoops
We present a new and fully general algorithm for the automated construction of the integrands of two-loop scattering amplitudes. This is achieved through a generalisation of the open-loops method to two loops.

The renormalization of vacuum expectation value parameters, such as v in the Standard Model (SM), is an important ingredient in electroweak renormalization, where this issue is connected to the treatment of tadpoles. Tadpole counterterms can be generated

Higher Order Electroweak and QCD Corrections in e+e−μ+μ− production at LHC [PDF]
This thesis focuses on improving the theoretical modelling of the process pp → e+e−μ+μ− at LHC by including both EW and QCD higher-order perturbative corrections.

Two-loop mixed QCD-EW corrections to neutral current Drell-Yan
We present the two-loop mixed strong-electroweak virtual corrections to the neutral current Drell-Yan process and we provide, as supplementary material, the explicit formulae of the infrared-subtracted finite remainder.

NLO electroweak corrections to multi-boson processes at a muon collider
We present results on NLO electroweak (EW) corrections to multiple massive boson production processes at a future muon collider. Inclusive cross sections with O $$ \mathcal{O} $$ (α) corrections for processes for up to four bosons in the final state as ...

Hadronic effects in Møller scattering at NNLO
Two-loop electroweak corrections to polarized Møller scattering are studied in two different schemes at low energies. We find the finite Q 2 corrections to be well under control.

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

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 ...

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