New data set recorded by Dø experiment at the Tevatron collider at s√ 1.96 TeV makes the diboson physics program an attractive probe of electroweak gauge structure in the Standard Model. Here we ...present the most recent diboson production cross section measurements at Dø for Wγ, Zγ, WZ and ZZ and report on the tightest limits to date on the neutral trilinear gauge boson couplings in Zγ production. Depending on the analysis the size of utilized RunIIa data collected during 2002-2006 by the Dø detector is 0.8-1.0 pb-1.
If no light Higgs boson exists, the interaction among the gauge bosons becomes strong at high energies (\(\sim 1 {\rm TeV}\)). The effects of strong electroweak symmetry breaking (SEWSB) could ...manifest themselves indirectly as anomalous couplings before they give rise to new physical states like resonances. Here a study of the measurement of trilinear gauge couplings is presented looking at the hadronic decay channel of the W boson at an \(e\gamma\)-collider. A sensitivity in the range of 10-3 to 10-4 can be reached depending on the coupling under consideration.

One option at the International Linear Collider is to convert the electron beams into high energy photon beams by Compton scattering a few millimetres in front of the interaction region. Selected ...physics channels for this option have been analysed and technical issues have been studied. So far no showstoppers for this option have been found.
The meteorological parameters: direct solar (DS) and relative ultraviolet solar (UV) irradiances, pressure (
p), temperature (
T), relative humidity (RH) and negative small air-ion concentration (
...n), have been measured at Belgrade during the partial (97.7%) solar eclipse on 11 August 1999. Correlation between DS, relative UV irradiances (Pearson's correlation coefficient,
r
=
0.7
) and theoretical prediction of insolation drop during the eclipse are presented. The atmospheric pressure was close to normal and practically constant. A “mirror symmetry” between
T and RH was observed. Correlation between RH and
n (
r
=
0.8
) was found and highlighted considering molecular collision processes. This correlation was confirmed in an indoor experiment (
r
=
0.95
) and it is related partly to the decrease of air-ion recombination rate with increase of RH during the eclipse.
Eur.Phys.J.C38:427-436,2005 If no light Higgs boson exists, the interaction among the gauge bosons
becomes strong at high energies (~1TeV). The effects of strong electroweak
symmetry breaking (SEWSB) ...could manifest themselves indirectly as anomalous
couplings before they give rise to new physical states like resonances. Here a
study of the measurement of trilinear gauge couplings is presented looking at
the hadronic decay channel of the W boson at an e-gamma - collider. A
sensitivity in the range of 10^{-3} to 10^{-4} can be reached depending on the
coupling under consideration.

The processes gamma gamma -> WW and e gamma -> nu W are sensitive to triple
gauge boson interactions. Both reactions have been simulated for hadronically
decaying W-bosons and the sensitivity to ...anomalous couplings has been
estimated.
