Non-minimal CW inflation, electroweak symmetry breaking and the 750 GeV anomaly [PDF]

open access: yes, 2015
A bstractWe study whether the hinted 750 GeV resonance at the LHC can be a Coleman-Weinberg inflaton which is non-minimally coupled to gravity. Since the inflaton must couple to new charged and coloured states to reproduce the LHC diphoton signature, the

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

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.

Measurement of the effective leptonic weak mixing angle

open access: yesJournal of High Energy Physics
Using pp collision data at s $$ \sqrt{s} $$ = 13 TeV, recorded by the LHCb experiment between 2016 and 2018 and corresponding to an integrated luminosity of 5.4 fb −1, the forward-backward asymmetry in the pp → Z/γ * → μ + μ − process is measured.

Evidence of pair production of longitudinally polarised vector bosons and study of CP properties in ZZ → 4ℓ events with the ATLAS detector at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2023
A study of the polarisation and CP properties in ZZ production is presented. The used data set corresponds to an integrated luminosity of 140 fb −1 of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the ...

(mu B)-driven Electroweak Symmetry Breaking

open access: yes, 2005
We consider a scenario in which the dominant quartic coupling for the Higgs doublets arises from the F-term potential, rather than the conventional SU(2)_L x U(1)_Y D-term potential, in supersymmetric theories.

Stabilization of the electroweak vacuum by a scalar threshold effect [PDF]

open access: yes, 2012
A bstractWe show how a heavy scalar singlet with a large vacuum expectation value can evade the potential instability of the Standard Model electroweak vacuum.

Dark Dimension With (Little) Strings Attached

open access: yesFortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Higgs Boson studies at future particle colliders

open access: yesJournal of High Energy Physics, 2020
This document aims to provide an assessment of the potential of future colliding beam facilities to perform Higgs boson studies. The analysis builds on the submissions made by the proponents of future colliders to the European Strategy Update process ...

Electroweak Strings, Zero Modes and Baryon Number

open access: yes, 1994
The Dirac equations for leptons and quarks in the background of an electroweak $Z-$string have zero mode solutions. If two loops of electroweak string are linked, the zero modes on one of the loops interacts with the other loop via an Aharanov-Bohm ...
