Theoretical physicists (I was one of them) are always ready to invent new particles (axions, neutralinos and now techni-quarks) and sometimes they are right (neutrinos) but this leaves the burden of finding them to the experimental physicists, who immediately demand a new accelerator to be built in order to detect them. So everybody is happy. Tullio |

No, I believe that the field (not only the particle) they found is really the field which was foreseen by Peter Higgs and other people in the Seventies. Unfortunately the Nobel Prize can only be given to three people. One was dead and the other 2 got it. I"ve just read on the New York Times that a Russian tycoon called Yuri Milner is giving prizes of three million dollars to 12 scientists, including Sam Perlmutter of UC Berkeley who already shared a Nobel prize in astrophysics. Another UC Berkeley scientist is Jennifer A.Doudna for research in biology with Emmanuelle Charpentier. The prizes have also been given to 5 mathematicians for which there is no Nobel prizes but only the Fields medal, with no money attached. The physicist forgotten by the Nobel Prize Committee for the Higgs boson is Jeffrey Goldstone, as also my friend Ben Segal of CERN agreed. Another who deserved it is Tullio Regge, who died at 81 a few days ago in his Torino.I have known him personally and he was a great man, not only a great physicist. Any physicist knows what a "Regge pole" is in elementary particle physics, but he also brought out new concepts in general relativity. Addio, Tullio. Tullio |

Thanks. The Scientific community, as of now is not agreeing they found Higgs. |

The University of Southern Denmark is NOT the scientific community. This is just an opinion. The LHC is being prepared to restart in 2015 to bring its energy from 7 TeV to 15 TeV to get more precise data. There is no need for a new accelerator, which may take ten years to build, if money is found. I am crunching LHC data both in vLHC@home and ATLAS@home, so I am involved in this search. Tullio |

Thanks. The Scientific community, as of now is not agreeing they found Higgs. AFIK they only claimed to have found something near the energy level that the Higgs is predicted to have. Higgs or ??? has to wait for billions of more observations. |

This is exactly in the CERN program. Next year LHC should reach its planned energy of 15 TeV and produce billions of events (600 millions/s). This will produce a huge amount of data which will be processed in the CERN Grid but also by volunteers at home. See the slides of Pete Jones and Wenjing Wu at the Budapest BOINC workshop in the BOINC home page. Tullio |

CERN Physicists Discover Two New Subatomic Particles Scientists working at CERN's Large Hadron Collider near Geneva, Switzerland have discovered two never-before-seen subatomic particles, the nuclear research facility announced today. Dubbed Xi_b'- and Xi_b*-, the particles are "heavyweight" particles known as baryons, CERN scientists said. Like the proton, the new particles are made up of three quarks but are more than six times as massive. http://www.huffingtonpost.com/2014/11/19/cern-physicists-two-new-subatomic-particles_n_6184878.html?utm_hp_ref=science Exciting! |

CERN Physicists Discover Two New Subatomic Particles Sure is! Thanx Lynn:) rOZZ Music Pictures |

The article submitted to Physical Review Letters has more than a thousand authors. Maybe I should in the list because the program PYTHIA used to discover the particles runs also on my computers in the vLHC@home project. Tullio |

Updates. LHCb experiment observes two new baryon particles never seen before Like the well-known protons that the LHC accelerates, the new particles are baryons made from three quarks bound together by the strong force. The types of quarks are different, though: the new X_ib particles both contain one beauty (b), one strange (s), and one down (d) quark. Thanks to the heavyweight b quarks, they are more than six times as massive as the proton. But the particles are more than just the sum of their parts: their mass also depends on how they are configured. Each of the quarks has an attribute called "spin". In the Xi_b'- state, the spins of the two lighter quarks point in the opposite direction to the b quark, whereas in the Xi_b*- state they are aligned. This difference makes the Xi_b*- a little heavier. CERN makes public first data of LHC experiments Geneva, 20 November 2014. CERN1 launched today its Open Data Portal where data from real collision events, produced by the LHC experiments will for the first time be made openly available to all. It is expected that these data will be of high value for the research community, and also be used for education purposes. rOZZ Music Pictures |

There is a new BOINC project, CMS-OpenData which makes use of some CERN data but I was unable to start it. First of all, it must require a 64-bit Virtual Box and then i get a Python error in the demoanalyzer_cfg,py file, which is hidden in a subdirectory of /mnt/.rw, so it is not easy to get there with a File Explorer.

CERN has launched another project based on distributed volunteer computing, called T4T_WebAPI. It is not a BOINC project, but you must have Virtual Box installed on your Windows, Linux or Mac OS X PC in order to run it. I am running it on a Windows 8.1 PC with 16 GB RAM, but it needs a minimum of 256 MB RAM. Of course the bigger your RAM is the better. See lhcathome2.cern.ch Tullio |

My computer (DELL, 64-bit, quad cpu's, 8 GB RAM, w/Windows 7), is, also, running the latest T4T program from CERN. No major problems, yet. |

CERN has launched a Grand Challenge competition for processing LHC data. It is not necessary to have a BOINC account, also Google, Facebook and Twitter accounts can participate. See lhcathome2.cern.ch. Tullio |

Update! CERN’s Large Hadron Collider gears up for run 2 Geneva, 12 December 2014. CERN1 announced today at the 174th session of the CERN Council that the Large Hadron Collider (LHC) is gearing up for its second three-year run. The LHC is the largest and most powerful particle accelerator in the world and the whole 27-kilometre superconducting machine is now almost cooled to its nominal operating temperature of 1.9 degrees above absolute zero. All teams are at work to get the LHC back online and the CERN Control Centre is in full swing to carry out all the requested tests before circulating proton beams again in March 2015. Run 2 of the LHC follows a 2-year technical stop that prepared the machine for running at almost double the energy of the LHC’s first run. rOZZ Music Pictures |
