OK, I won't discuss its value. But it will be published in Physical Review LETTERS on September 4 and it is available online before that date. Should it be a breakthrough worthy of a Nobel prize, which would be its publication date? The September issue of CERN Courier does not mention it.

I like this quote Julie.
"The Standard Model says the world interacts with all leptons in the same way. There is a democracy there. But there is no guarantee that this will hold true if we discover new particles or new forces," said study co-author and UMD team lead Hassan Jawahery, Distinguished University Professor of Physics and Gus T. Zorn Professor at UMD. "Lepton universality is truly enshrined in the Standard Model. If this universality is broken, we can say that we've found evidence for non-standard physics."

Finding new forces makes me think of anti-forces just like there is anti-matter.

CALET docks on the International Space Station

CALET will perform accurate measurements of the electron energy spectrum from 1 GeV to 20 TeV. “The high end of the spectrum could be particularly interesting as it could help resolve the controversial interpretation of the electron and positron spectra measured by AMS-02 and could provide a clue on possible signatures of dark matter,” says John Wefel of Louisiana State University, Co-PI of the CALET project and lead of the American team participating in CALET.


Photographers, capture behind-the-scenes at CERN

CERN is teaming up with seven other large physics laboratories for an international photo competition, the 2015 Global Physics Photowalk (link is external). On 25 and 26 September, photographers from around the world will be given the opportunity to take photographs behind the scenes at these prestigious laboratories.

Update: "God particle", that word needs to go.

2 experiments unveil sharper details about Higgs boson, largely in line with predictions

GENEVA (AP) — After three years of scrutinizing the elusive Higgs boson closely, scientists say they've determined that the "God particle" behaves just as predicted.

The European Organization for Nuclear Research, known by its French acronym CERN, said Tuesday two experiments that previously helped confirm the particle have produced the most precise measurements yet of its decay and interaction with other particles.

Yes. Especially when Higgs collegues called it the "God Damn Particle" from the beginning:)
The term was originated by the former director of Fermilab and Nobel laureate Leon Lederman.

'Littlest' quark-gluon plasma revealed by physicists using Large Hadron Collider

Researchers at the University of Kansas working with an international team at the Large Hadron Collider have produced quark-gluon plasma—a state of matter thought to have existed right at the birth of the universe—with fewer particles than previously thought possible.

"This is the first paper that clearly shows multiple particles are correlated to each other in proton-lead collisions, similar to what is observed in lead-lead collisions where quark gluon plasma is produced," said Yen-Jie Lee, assistant professor of physics at MIT and co-convener of the CMS heavy-ion physics group. "This is probably the first evidence that the smallest droplet of quark gluon plasma is produced in proton-lead collisions."
The KU researcher described quark-gluon plasma as a very hot and dense state of matter of unbound quarks and gluons—that is, not contained within individual nucleons.

LHC signal hints at cracks in physics' standard model

Collider spots same anomaly seen by two other experiments, but more data are needed to claim a discovery.

An intriguing signal from the Large Hadron Collider (LHC) might prove to be the crack that prises apart the standard model — physicists’ current best description of how matter and forces interact.

Analysis of data gathered during 2011–12 at the collider at CERN, Europe’s particle-physics laboratory near Geneva, Switzerland, suggests that in particular decays, short-lived particles called B-mesons create taus more frequently than they create muons. (Taus and muons are heavier cousins of electrons.) But the standard model says that once the particles’ mass differences are taken into account, the decays should occur at exactly the same rate. The finding will be published in Physical Review Letters this month (and has been on the arXiv1 pre-print server since June).

2.1 Sigma is not significant. But, since I am running both ATLAS@home and CMS-dev, I shall be watching.

Photos: A behind-the-scenes look at CERN's ALICE

ALICE
Recently, after a more than two-year hiatus, CERN's Large Hadron Collider (LHC) began delivering data again. Let's take a look at one of its most important experiments, ALICE.

ALICE stands for A Large Ion Collider Experiment.

CAST explores the dark side of the universe

Over the next 10 days, CERN's Axion Solar Telescope (CAST) will receive the Sun's rays. The Sun's course is visible from the window in the CAST experimental hall just twice a year, in March and September. The scientists will take advantage of these few days to improve the alignment of the detector with respect to the position of the Sun to within a thousandth of a radian.
Outside of this alignment operation, CAST tracks the Sun but does not see it. The astroparticle experiment is searching for solar axions, hypothetical particles that are thought to interact so weakly with ordinary matter that they pass through walls unimpeded. It is in order to catch these elusive particles that the CAST detector tracks the movement of the Sun for an hour and a half at dawn and an hour and a half at dusk.

Axions were postulated to solve the problem of a discrepancy between the theory of the infinitely small and what is actually observed. They were named after a brand of washing powder because their existence may allow the theory to be “cleaned up”. If they exist, axions could also be good candidates for the universe’s dark matter. Dark matter is thought to represent 80% of the matter of the universe, but its nature remains unknown.

I just had to Google it and there it was - Axion dishwashing paste, made and sold in Costa Rica.
Having most of the universe named after your product would be the ultimate advertising coup, I would think.

Antihydrogen at CERN: 20 years and going strong:)
Twenty years ago a team of scientists at CERN led by Walter Oelert succeeded in producing the first atoms made of antimatter particles.
The nine atoms of antihydrogen – the antimatter counterpart of the simplest atom, hydrogen – were made at CERN’s Low Energy Antiproton Ring (LEAR) facility. This world premiere happened exactly 30 years after the discovery of the antiproton and opened a new chapter in the study of antimatter.

On the October 8 issue of "Nature" there is a link to a notice I cannot read because it givesm me a DOI error(?). The title speaks of a new kind of accelerator being developed at CERN which uses particle "surfing" an electric field. It should be much shorter than current circular accelerators like LHC and uses much less energy. I am waiting for further informations.
