Measurement of the electroweak production of dijets in association with a Z-boson and distributions sensitive to vector boson fusion in proton-proton collisions at √s= 8 TeV using the ATLAS detector [PDF]

open access: yes, 2014
Measurements of fiducial cross sections for the electroweak production of two jets in association with a Z-boson are presented. The measurements are performed using 20.3 fb−1 of proton-proton collision data collected at a centre-of-mass energy of s√ = 8 ...

Higher-Order Electroweak Contributions to Indirect CP Violation in Neutral Kaons [PDF]

open access: yes, 2022
The parameter ϵK is an important measure of the imbalance between matter and antimatter in the neutral kaon (K0 and K¯0) system. In particular, ϵK provides a highly sensitive probe of new physics and plays a critical role in the global fit of the Cabibbo-

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

open access: yesBer Wiss
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 ...

Higher-order supersymmetric contributions to electroweak precision observables [PDF]

open access: yes, 2005
The dominant electroweak two-loop corrections to the precision observables M(_w) and sin(^2) θ off are calculated in the MSSM. They are obtained by evaluating the two loop Yukawa contributions of ϭ (aas) and ϭ (at2), ϭ (a2ab), ϭ (a2b), to the quantity Ap.

Measurement of the low-mass Drell-Yan differential cross section at √s = 7 TeV using the ATLAS detector [PDF]

open access: yes, 2014
The differential cross section for the process Z/γ ∗ → ℓℓ (ℓ = e, μ) as a function of dilepton invariant mass is measured in pp collisions at s√ = 7 TeV at the LHC using the ATLAS detector.

Two-loop mixed QCD-EW corrections to neutral current Drell-Yan

open access: yesJournal 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.

Singular Higher-Order Complete Vector Bases for Finite Methods [PDF]

open access: yes, 2004
This paper presents new singular curl- and divergence- conforming vector bases that incorporate the edge conditions. Singular bases complete to arbitrarily high order are described in a unified and consistent manner for curved triangular and ...

Combining initial-state resummation with fixed-order calculations of electroweak corrections [PDF]

open access: yes, 2017
We present a resummation of those double-logarithmically enhanced electroweak correction that arise in pp colliders because protons are not SU(2) singlets, by solving DGLAP equations in the full Standard Model.

Electroweak renormalization based on gauge-invariant vacuum expectation values of non-linear Higgs representations. Part I. Standard Model

open access: yesJournal of High Energy Physics, 2022
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

NLO electroweak corrections to multi-boson processes at a muon collider

open access: yesJournal 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 ...
