The experimental discovery of the W and Z bosons at CERN in 1983 confirmed the detailed predictions of the electroweak theory, which unifies the electromagnetic and weak nuclear forces. After a brief introduction to the most important ideas in this force unification, this account describes the ...

W particle, one of two massive electrically charged subatomic particles that are thought to transmit the weak force—that is, the force that governs radioactive decay in certain kinds of atomic nuclei. According to the Standard Model of particle physics
Production of Almost Fermiophobic Gauge Bosons in the Minimal Higgsless Model at the LHC We study the production of the heavy W' and Z' bosons in the three site higgsless model at the LHC. We focus on the s-channel production mode to estimate t... T Ohl,C Speckner - 《Physical Revi...
Artificial intelligence and machine learning are becoming indispensable tools in many areas of physics, including astrophysics, particle physics, and climate science. In the arena of quantum materials, the rise of new experimental and computational techn
In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts. Ten years later, and with the data corresponding to the production of a 30-times larger number of Higgs bosons, we have...
It was only the resilience and conviction of Carlo Rubbia, who shared the 1984 Nobel Prize in Physics with van der Meer for the project leading to the discovery of the W and Z bosons, that kept the project alive. Rubbia, who became Director-General of CERN in 1989, argued that, in ...
The Higgs-gauge bosons couplings ghVV(V = g, γ, W, Z) receive non-decoupling corrections due to heavy quanta, and deviations from the SM predictions can be used to test its presence. The possible Higgs signal recently reported at LEP, with m...

and the heavy W and Z bosons for the weak interaction. The SM has been very successful in providing accurate predictions for essentially all particle physics experiments carried out so far. In 2012, the final missing particle of the SM, the Higgs boson, was observed by the ATLAS1and CMS2,...
