The Nobel committee decided Englert and Higgs should jointly take the accolade for the boson, discovered at Cern in 2012 Higgs boson scientists win Nobel prize in physics ______________________ Voyager 1 exits solar system; let's hope aliens bring it back Lynn |

In a Test4Theory@home message board I had asked if the Higgs boson gives mass only to leptons or also to hadrons. Here is the answer given by dr.Peter Skands of the CERN Theory Division: "The Higgs field (not the Higgs boson) gives mass to both leptons and quarks (in addition to the W and Z bosons, and yes, also to the Higgs boson itself). However, although the up and down quarks, for instance, therefore do acquire some "Higgs mass", that mass is hundreds of times smaller than, say, the mass of the proton (which can be approximated as being made up of two up quarks and one down quark). The Higgs field therefore only plays a relatively minor role in generating the total mass of the proton. Most of the proton mass is generated by the strong interaction (quantum chromodynamics - QCD), via interactions with so-called quark and gluon condensates in the vacuum, another extremely interesting phenomenon which, however, is not the subject of today's Nobel prize )" Tullio |

The search is not ended and will continue after the LHC upgrade from 2015 to determine all the properties of the particle such as spin. Tullio |

I've read an interview with Peter Higgs in the "New scientist". He speaks of the Brout-Engler-Higgs mechanism, not only of the Higgs boson. My friend Peter Skands, a CERN theoretical physicist, wrote in a post in the Test4Theory@home message boards that what gives mass to particles, including the Higgs boson, is the Higgs field. Since Brout is dead, he could not be assigned the Nobel prize. Tullio |

Turning energy into mass.... cool... |

The search is not ended and will continue after the LHC upgrade from 2015 to determine all the properties of the particle such as spin. I assume here Tullio that since this is a bosun type structure it will posses a positive integer spin such as that of the photon, too, another bosun type structure.

In the standard model, the Higgs is a boson with no spin. |

In the standard model, the Higgs is a boson with no spin. Does that mean that anything with a negative spin would not be classed as having a bosun type structure?

A real Higgs boson should have spin zero. A photon has spin one, the graviton, if it exists, should have spin 2. All bosons have integer spins, all fermions half integer spin and obey the Pauli exclusion principle. The discovery of spin by Goudsmit and Uhlenbeck never received a Nobel prize. Tullio |

How many side with Stephen Hawking?? Stephen Hawking: physics would be 'more interesting' if Higgs boson hadn't been found |

Yes, and they are already planning a 100 TeV Very Large Hadron Collider with a 100 km circumference under the Geneva Lake to discover other particles. Cost: ten billion dollars. This is the "Spiral of high energies" described by Angelo Baracca and Silvio Bergia in their book in 1975. Tullio |

Decoherence is a major hurdle in quantum computing. Now scientists at Simon Fraser University seem to have overcome it. Go, Canada! Tullio |
