Vacuum stability with radiative Yukawa couplings

open access: yesJournal of High Energy Physics, 2022
We explore the electroweak vacuum stability in the framework of a recently proposed paradigm for the origin of Yukawa couplings. These arise as low energy effective couplings radiatively generated by portal interactions with a hidden, or dark, sector at ...

N-jettiness in electroweak high-energy processes

open access: yesJournal of High Energy Physics, 2022
We study N-jettiness in electroweak processes at extreme high energies, in which the mass of the weak gauge bosons can be regarded as small. The description of the scattering process such as e − e + → μ − μ + + X is similar to QCD.

Probing anomalous off-shell electroweak dipole moment of the top quark

open access: yesEPJ Web of Conferences, 2017
A possibility to search for anomalous Wtb interaction ∂μWμ−b¯ f W L P L + f W R P R t is considered for the first time. Despite such couplings do not contribute to both pair top quark production or three main electroweak production ...

About the rapidity and helicity distributions of the W bosons produced at LHC

open access: yesJournal of High Energy Physics, 2017
W bosons are produced at LHC from a forward-backward symmetric initial state. Their decay to a charged lepton and a neutrino has a strong spin analysing power. The combination of these effects results in characteristic distributions of the pseudorapidity

LEvEL: Low-Energy Neutrino Experiment at the LHC

open access: yesJournal of High Energy Physics, 2021
We propose the operation of LEvEL, the Low-Energy Neutrino Experiment at the LHC, a neutrino detector near the Large Hadron Collider Beam Dump. Such a detector is capable of exploring an intense, low-energy neutrino flux and can measure neutrino cross ...

Higgs vacuum stability and modified chaotic inflation

open access: yesPhysics Letters B, 2017
The issue of electroweak vacuum stability is studied in presence of a scalar field which participates in modifying the minimal chaotic inflation model.

Ground-state β-feeding determination using total-absorption spectrometers

open access: yesFrontiers in Physics
The determination of the β intensity probability between the ground states of parent and daughter nuclei has traditionally been a difficult task with standard γ-spectroscopy approaches due to the lack of the associated γ emission.

Studies of Zγ production in association with a high-mass dijet system in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
The production of a Z boson and a photon in association with a high-mass dijet system is studied using 20.2 fb−1 of proton-proton collision data at a centre-of-mass energy of s = 8 $$ \sqrt{s}=8 $$ TeV recorded with the ATLAS detector in 2012 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.

Simulation of a Three‐Nucleons System Transition on Quantum Circuits

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 5, May 2025.
A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.
