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.

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.

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.
”Launching the CERN Open Data Portal is an important step for our Organization. Data from the LHC programme are among the most precious assets of the LHC experiments, that today we start sharing openly with the world. We hope these open data will support and inspire the global research community, including students and citizen scientists,” said CERN Director General Rolf Heuer.

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

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.

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.
“With this new energy level, the LHC will open new horizons for physics and for future discoveries,” said CERN Director General Rolf Heuer. “I’m looking forward to seeing what nature has in store for us”.

Islamic Republic of Pakistan to become Associate Member State of CERN


Geneva 19 December 2014. CERN Director General, Rolf Heuer, and the Chairman of the Pakistan Atomic Energy Commission, Ansar Parvez, signed today in Islamabad, in presence of Prime Minister Nawaz Sharif, a document admitting the Islamic Republic of Pakistan to CERN Associate Membership, subject to ratification by the Government of Pakistan.
“Pakistan has been a strong participant in CERN’s endeavours in science and technology since the 1990s,” said Rolf Heuer. “Bringing nations together in a peaceful quest for knowledge and education is one of the most important missions of CERN. Welcoming Pakistan as a new Associate Member State is therefore for our Organization a very significant event and I'm looking forward to enhanced cooperation with Pakistan in the near future.”

I have known one Pakistani scientist, Abdus Salam, Nobel prize winner. Now the International Center for Theoretical Physics, founded by him in Miramare, near Trieste, bears his name. I've read in the December issue of Cern Courier that the ICTP. now directed by a Mexican scientist, will expand its mission to Third World countries, as proposed by Salam.

Australian scientists helping to unlock mysteries of the universe at CERN

Physicist Amelia Brennan knows more than most about the stuff that holds the universe together.

She recently returned to Melbourne after a stint at CERN – the European Organisation for Nuclear Research in Geneva - where the sub-atomic Higgs boson or "God particle" was discovered in 2013.

Despite the discovery, hailed as a major scientific breakthrough, Ms Brennan said she and her CERN colleagues could still only account for 25 per cent of the matter in the universe.

I wish people would start referring to the Higgs Boson asa "God's particle". That was a publisher's idea for a fast selling book by Leo Lederman. He had wanted to call it the "Goddam particle", because it was so difficult to find it.

One thing I've learned from my CERN friends is that the Higgs field (and not the boson) gives mass only to weakly interacting particles, like the W and Z intermediate vector bosons, and not to strong interacting particles like quarks, whose mass is due mostly to the nuclear strong interaction. Of course the Higgs field also gives mass to the Higgs boson.
