The Standard Model Theory of Neutron Beta Decay

open access: yesUniverse, 2023
We review the status of the Standard Model theory of neutron beta decay. Particular emphasis is put on the recent developments in the electroweak radiative corrections.

Light scalaron as dark matter

open access: yesPhysics Letters B, 2021
A new cosmological scenario is proposed in which a light scalaron of f(R) gravity plays the role of dark matter. In this scenario, the scalaron initially resides at the minimum of its effective potential while the electroweak symmetry is unbroken. At the

Topological interaction of neutrino with photon in a magnetic field — Electroweak Hall effect

open access: yesPhysics Open, 2023
The effective interaction of a neutrino with a photon in magnetized plasma is obtained from a strong field expansion in the electroweak standard model.

Cross-section measurements for the production of a Z boson in association with high-transverse-momentum jets in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
Cross-section measurements for a Z boson produced in association with high-transverse-momentum jets (p T ≥ 100 GeV) and decaying into a charged-lepton pair (e + e − , μ + μ − ) are presented.

Measurement of electroweak Z ν ν ¯ γjj $$ Z\left(\nu \overline{\nu}\right)\gamma jj $$ production and limits on anomalous quartic gauge couplings in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
The electroweak production of Z ν ν ¯ γ $$ Z\left(\nu \overline{\nu}\right)\gamma $$ in association with two jets is studied in a regime with a photon of high transverse momentum above 150 GeV using proton–proton collisions at a centre-of-mass energy of ...

Next-to-leading-order QCD and electroweak corrections to triple-W production with leptonic decays at the LHC

open access: yesJournal of High Energy Physics, 2020
We present a calculation of the next-to-leading-order QCD and electroweak corrections to WWW production with leptonically decaying W bosons at the LHC, fully taking into account off-shell contributions, intermediary resonances, and spin correlations. The

An effective field theory approach for electroweak interactions in the high energy limit

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We present an effective action for the electroweak sector of the standard model valid for the calculation of scattering amplitudes in the high energy (Regge) limit.

Zero-range effective field theory for resonant wino dark matter. Part III. Annihilation effects

open access: yesJournal of High Energy Physics, 2018
Near a critical value of the wino mass where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold, low-energy winos can be described by a zero-range effective field theory (ZREFT) in which the winos interact nonperturbatively ...

High-precision determination of the Ke3 radiative corrections

open access: yesPhysics Letters B, 2021
We report a high-precision calculation of the Standard Model electroweak radiative corrections in the K→πe+ν(γ) decay as a part of the combined theory effort to understand the existing anomaly in the determinations of Vus.
