The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post-War Period. [PDF]
Ber WissAbstract 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 ...

Beam polarization effects on top-pair production at the ILC. [PDF]
Eur Phys J C Part Fields, 2018 Full one-loop electroweak-corrections for an $e^-e^+\rightarrow t \bar{t}$ process associated with sequential $t\rightarrow b \mu\nu_\mu$ decay are discussed. At the one-loop level, the spin-polarization effects of the initial electron and positron beams

Feynman-diagram evaluation in the electroweak theory with computer algebra [PDF]
, 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 535, Issue 12, December 2023., 2023 This article describes the implementation of low‐frequency axion haloscope setups inside the future BabyIAXO magnet. The RADES proposal has a potential sensitivity to the axion‐photon coupling down to values corresponding to the KSVZ model, in the mass range between 1 and 2 μ$\umu$eV.

Computing Techniques for Two-Loop Corrections to Anomalous Magnetic Moments of Leptons [PDF]
, 1996 Two-loop electroweak corrections to the electron, muon, and tau lepton anomalous magnetic moments have been computed recently. Effects of hadronic contributions to the photon propagator in two-loop QED corrections have also been reanalysed.

The global electroweak fit at NNLO and prospects for the LHC and ILC [PDF]
, 2014 For a long time, global fits of the electroweak sector of the Standard Model (SM) have been used to exploit measurements of electroweak precision observables at lepton colliders (LEP, SLC), together with measurements at hadron colliders (Tevatron, LHC ...

Supersymmetric and non-supersymmetric models without catastrophic Goldstone bosons. [PDF]
Eur Phys J C Part Fields, 2017 The calculation of the Higgs mass in general renormalisable field theories has been plagued by the so-called "Goldstone Boson Catastrophe", where light (would-be) Goldstone bosons give infra-red divergent loop integrals.

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 ...

Automation of electroweak corrections for LHC processes [PDF]
, 2015 For the Run 2 of the LHC next-to-leading order electroweak corrections will play an important role. Even though they are typically moderate at the level of total cross sections they can lead to substantial deviations in the shapes of distributions.

Top-quark physics in six-quark final states at the Next Linear Collider [PDF]
, 1999 The processes of six-quark production with one $b\bar b$ pair are studied by means of a complete tree-level electroweak calculation. The top-quark signal is examined: the importance of electroweak backgrounds, of the order of 10% above the $t\bar t ...
