Probing Anomalous Gauge Boson Couplings at LEP [PDF]
, 1994 We bound anomalous gauge boson couplings using LEP data for the $Z\rightarrow {\overline f} f$ partial widths. We use an effective field theory formalism to compute the one-loop corrections resulting from non-standard model three and four gauge boson ...

Spectroscopic Investigations on Polyvinylidene Fluoride Nanofibers
Macromolecular Chemistry and Physics, Volume 227, Issue 1, 15 January 2026.The fabrication of Polyvinylidene fluoride nanofibers from solution by force‐spinning is reported. Polymer mats were obtained at spinning rates ranging from 4000 to 10 000 rotations per minute. Raman and X‐ray data confirm the dominant α phase with a small admixture of β. The β‐phase content increases from 15% to over 70% as the spinning rate increases.

Physics Letters B, 1985 Abstract We show at leading order of the 1/ N expansion that composite gauge fields in a supersymmetric U(4 n + 2)/U(4 n ) × SU(2) non-linear sigma model become dynamical in some range of parameters. Since the hidden local symmetry in this sigma model is identifiable with a weak SU(2) of the standard electroweak model, we suggest that the observed ...

Journal of High Energy Physics, 2018 We construct a self-interacting dark matter model that could simultaneously explain the observed muon anomalous magnetic moment. It is based on a gauged U1Lμ−Lτ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ extension of the standard model, where we ...

Excited States of Coherent Harmonic Qubits With Long‐Range Photon Coupling and Dissipation
Annalen der Physik, Volume 537, Issue 12, December 2025.When N qubits are strongly coupled with photons in a cavity, they can condense into a ground state with negative energy gap. Some new information is found on coherent transitions among excited states of this system, by simulating them numerically for small N.

Gauge Boson Mixing in the 3-3-1 Models with Discrete Symmetries
Advances in High Energy Physics, 2012 The mixing among gauge bosons in the 3-3-1 models with the discrete symmetries is investigated. To get tribimaximal neutrino mixing, we have to introduce sextets containing neutral scalar components with lepton number L=1,2.

Annalen der Physik, Volume 537, Issue 12, December 2025.A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

CP violation in loop-induced diboson production
Journal of High Energy PhysicsWe consider the impact of CP-violating Higgs and top interactions on diboson production from gluon fusion within the Standard Model Effective Field Theory framework.

General structure of gauge boson propagator and its spectra in a hot magnetized medium
European Physical Journal C: Particles and Fields, 2019 Based on transversality condition of gauge boson self-energy we have systematically constructed the general structure of the gauge boson two-point functions using four linearly independent basis tensors in presence of a nontrivial background i.e.

Supercurrents and Tunneling in Massive Many‐Vortex Necklaces and Star‐Lattices
Annalen der Physik, Volume 537, Issue 12, December 2025.It is numerically shown how massive many‐vortex systems, in a mixture of Bose–Einstein condensates, can host the bosonic tunneling of the infilling component in an almost‐periodic way when the vortices are organized in necklaces or star‐lattices. The purpose is to explore the conditions for the onset of Josephson supercurrents in rotating many‐vortex ...
