Theoretical and phenomenological aspects of vector boson production [PDF]

, 2000
The production of three gauge bosons in high-energy collisions - in particular in view of a next-linear collider with center of mass energies in the TeV range - offers an unique opportunity to probe the Standard Model (SM) of today's particle physics. In

Using DUNE to shed light on the electromagnetic properties of neutrinos

Journal of High Energy Physics, 2022
We study future DUNE sensitivity to various electromagnetic couplings of neutrinos, including magnetic moments, milli-charges, and charge radii. The DUNE PRISM capabilities play a crucial role in constraining the electron flavored couplings. We find that

Triboson production in the SMEFT

Journal of High Energy Physics
We study the production of three electroweak gauge bosons at the LHC, in the effective field theory of the standard model, at dimension six and next-to-leading order in QCD.

Complementary constraints on Zb b ¯ $$ Zb\overline{b} $$ couplings at the LHC

Journal of High Energy Physics, 2023
We propose a new strategy to probe the Z boson couplings to bottom and charm quarks at the LHC. In this work we mainly focus on the case of bottom quarks. Here, the Z boson is produced in association with two b-jets and decays to electrons or muons.

Primer on Axion Physics

Annalen der Physik, Volume 536, Issue 1, January 2024.
A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.

Hint for a Minimal Interaction Length in e+e−⟶γγ Annihilation in Total Cross Section of Center‐of‐Mass Energies 55‐207 GeV

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
The measurements of the total cross section of the e+e−⟶γγ(γ) reaction from the VENUS, TOPAS, OPAL, DELPHI, ALEPH, and L3 collaborations, collected between 1989 and 2003, are used to perform a χ2 test to validate the current quantum electrodynamics (QED) theory and search for possible deviations with the direct contact term annihilation. By observing a

New physics off the Z-pole: e + e − → f f ¯ $$ f\overline{f} $$ at Future Lepton Colliders

Journal of High Energy Physics
We explore the prospects for probing new physics (NP) beyond the Standard Model (SM) at the future lepton colliders through precision measurements of e + e − → f f ¯ $$ f\overline{f} $$ observables off the Z resonance.

Tracing the bottom electroweak dipole operators at future lepton colliders

Journal of High Energy Physics
While often omitted in the SMEFT analyses of electroweak measurements, the electroweak dipole operators of the bottom quark have been found to be important in some cases and are also related to processes involving the top quark. In this paper, we further
