CERN Large Hadron Collider

What has been presented is an outline of an SU(2) x SU(2) electroweak theory that can give rise to the non-Abelian 0(3)b theory of quantum electrodynamics on the physical vacuum. The details of the fermions and their masses has yet to be worked through, as well as the mass of the A boson. This vector boson as well as the additional fermions should be observable within the 10-Tev range of energy. This may be accessible by the CERN Large Hadron Collider in the near future. 

The existence of this propagator will be the largest addition to the physics of electroweak interactions when electromagnetism is nonAbelian. Further discussion on the subject of 51/(2) x 51/(2) electroweak theory is given by the authors in [4], Estimates on the mass of this boson are around four times the mass of the Zo boson and should be observable with the CERN Large Hadron Collider.

The Large Hadron Collider is an accelerator scheduled for completion in the year 2005 at the CERN laboratory near Geneva Switzerland. It will accelerate protons to an energy of 8 TeV. At that energy, the protons will have a speed only about one part in 130 million slower than the speed of light.

The Large Hadron Collider at CERN studies the properties of subatomic particles and nuclear matter. 

CERN (Conseil Europeen pour la Recherche Nucleaire) The European Laboratory for Particle Physics, formerly known as the European Organization for Nuclear Research, which is situated close to Geneva in Switzerland and is supported by a number of European nations. It runs the Super Proton Synchrotron (SPS), which has a7-kilometre underground tunnel enabling protons to be accelerated to 400 GeV, and the Lai e Electron-Positron Collider (LEP), in which 50 GeV electron and positron beams are collided. The Large Hadron Collider began operation in September 2008.

Engineering also facilitates science in many ways, the largest scale example being the Large Hadron Collider (LHC) at the European Organisation for Nuclear Research (CERN).

There is still hope that the somewhat more modest European project for a Large Hadron Collider (LHC) with 8 TeV -I- 8 TeV proton-proton collision, will go ahead. A final decision was due during 1994. After much procrastination the CERN Council finally voted in favour of the project in December 1994. The construction will proceed in stages, with full-scale operation planned for 2008 ...

The Large Hadron Collider at CERN was designed to prove or disprove the existence of the Higgs boson. A very powerful particle accelerator was needed, because Higgs bosons might not be seen in lower energy experiments, and because huge numbers of collisions would need to be studied. 

The Higgs potential is introduced ad hoc, and its reality cannot be confirmed experimentally directly, but the consequences of its existence were confirmed by observing the Higgs boson in experiments with the Large Hadron Collider at CERN in 2012. This indirectly confirmed also the idea that aU our observations are about one of the degenerate states of the broken symmetry of the Universe. Similar Higgs-field behavior was observed in superconductors [84] (coherent excited states in superconducting condensates with SSB were predicted earlier [85]). 

In 1999 Matey Mateev became a member of the European Center for Nuclear Research (CERN) in Switzerland. Bulgaria s active participation in CERN s experimental and theoretical research was one of his major services to science and to his country. He became a member of the Committee for Bulgaria s Cooperation with CERN and of the Board of CERN, where he represented Bulgaria throughout the period 1999-2000 and was the team leader of Bulgarian scientists invited to work at the Large Hadron Collider on its activation in CERN. 

Hadron showers (jets) from quarks and gluons produced in the decay of weak bosons as detected in high-energy electron-positron collisions by the OPAL Collaboration (OPAL 2003) at the Large Electron Positron Collider at CERN. Upper left the decay of a Z boson to a quark and an antiquark, e+e+ Z q + q (two jets). Upper right a Z boson decays to a pair of b quarks (as identified by jet properties) and one of them emits a gluon, e+e+ Z b + b + g (three jets). Below a W W pair decays to two quark-antiquark pairs (four jets). The sizes of boxes indicate the particle energies deposited in the detector elements...
