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 ...

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.

Two-loop mixed QCD-EW corrections to neutral current Drell-Yan
Journal of High Energy Physics, 2022 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.

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.

NLO electroweak corrections to multi-boson processes at a muon collider
Journal of High Energy Physics, 2022 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 ...

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 ...

Supersymmetric and non-supersymmetric models without catastrophic Goldstone bosons [PDF]
, 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.

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 ...

Automation of NLO QCD and EW corrections with Sherpa and Recola [PDF]
, 2017 This publication presents the combination of the one-loop matrix-element generator Recola with the multipurpose Monte Carlo program Sherpa. Since both programs are highly automated, the resulting Sherpa+Recola framework allows for the computation of -in ...

Hadronic effects in Møller scattering at NNLO
Journal of High Energy Physics, 2022 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.
