The June issue of CERN Courier, in an article dedicated to the computing needs of LHC, says that volunteer computing (us) has reached one half of the batch computing power of CERN, that is it is equivalent to a Tier 2 computer in the CERN GRID. Tier 0 computers are at Geneva and Budapest.

In Theory: Is theoretical physics in crisis?

"We are struggling to find clear indications that can point us in the right direction. Some people see in this state of crisis a source of frustration. I see a source of excitement because new ideas have always thrived in moments of crisis." - Gian Giudice, head of the Theory Department at CERN.

We are charting new seas, out of the doldrums of the Standard Model. I am happy to take part in it. Somehow lately, CERN has recognized the value of our volunteer contributions.

I think the theories claiming that we humans use less than 10% of our brains were from a time when much less was understood about how it functions. They were also a means of providing hope that someday when humans end up using more of the brain all our problems would be easy to solve.

My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events.

I think we have many capabilities when we are young and lose them as we get older. Think of children learning any language from parents speaking different languages. I know one girl speaking Chinese with her Chinese mother and Italian with her father and comrades at the school. All sons of immigrants in Italy speak good Italian, whatever their origin.

CLOUD shows pre-industrial skies cloudier than we thought

Our planet’s pre-industrial climate may have been cloudier than presently thought, shows CERN’s CLOUD experiment in two papers published today in Nature (link is external).
CLOUD shows that organic vapours emitted by trees produce lots of aerosol particles in the atmosphere when there’s no sulphuric acid – a main product of burning fossil fuels.
Previously, it was thought that sulphuric acid was essential to initiate the formation of these aerosol particles but the new research shows that these so-called biogenic vapours are also key to their growth, and can help them grow up to sizes where they can seed clouds.

Make music with ATLAS data

From techno beats to classical melodies, from jazz swinging to pop and rock riffs – the ATLAS experiment can play them all thanks to Quantizer (link is external).
This new platform translates ATLAS events into notes and rhythms, meaning one of the most complex scientific instruments in the world will not only search for new physics, but also generate music.

Is Particle Physics About to Crack Wide Open?

Hints of an unexpected new particle could be confirmed within days—and if it is, the Standard Model could be going down

It’s very similar to the signal that led to the discovery of the Higgs boson in 2012. But this particle is not the Higgs boson: it is six times more massive. Nobody had predicted anything like this. It is shocking to the physicists.

The Standard Model of particle physics describes what the building blocks of the universe are and how they work, and from there, at least in principle, explains every other phenomenon in nature. Originally theorists thought that the Standard Model would be an approximation of a more fundamental theory that would be quickly discovered.

Nice to see that physics does not discover only something that was predicted a hundred years ago like gravitational waves or 50 years ago like the Higgs boson.
We are charting new territory and, like Columbus,we may make an unforeseen discovery.

Has this discovery possibly got anything to do maybe with supersymmetry ??

---

No, I don't think so. I never heard a theorist claiming so. They would be happy to have an experimental confirmation of SUSY.

tullio I thought you mite find this interesting . SUSY

Thanks. It is a nice theory, but has no experimental evidence. The new 750 GeV bump does not fit into it.

First beam enters unique AWAKE experiment

AWAKE (the Advanced Proton Driven Plasma Wakefield Acceleration Experiment) will be the first accelerator of its kind in the world. It is currently under construction, but hopes to test the concept that plasma wakefields driven by a proton beam could accelerate charged particles.

http://www.upi.com/Science_News/2016/07/05/Large-Hadron-Collider-finds-three-new-particles-confirms-fourth/9611467723639/?spt=mps&or=3

GENEVA, Switzerland, July 5 (UPI) -- Europe's largest particle accelerator, the Large Hadron Collider, is back in action. According to two newly published studies, its latest round of experiments yielded three new "exotic" particles and confirmed the existence of a fourth.

The newly identified particles are considered "exotic" because they contain four quarks, the building blocks of all matter. Particle physicists used to believe all particles were composed of mesons, a quark-antiquark pair, or baryons, three quarks -- but no more than three quarks. A litany of discoveries have shown otherwise.

The exotic particles are named for their reconstructed mass in megaelectronvolts -- a single electronvolt is approximately 160 zeptojoules, a tiny fraction of a joule. The particle X(4140), for example, has a mass of 4,140 megaelectronvolts. Scientists had previously observed X(4140); the latest findings confirm its existence.

Three heavier exotic particles spotted by CERN physicists -- X(4274), X(4500) and X(4700) -- had never been seen before.

"Even though the four particles all contain the same quark composition, they each have a unique internal structure, mass and their own sets of quantum numbers," researchers explained in a news release.

Continued research is necessary to further illuminate the idiosyncrasies of each exotic particle.

The latest findings are detailed in two papers, both published online in the open source journal Arxiv.

LHC performance reaches new highs

Some 2076 bunches of 120 billion protons are currently circulating in the ring in each direction. At the end of June, beams were maintained in the accelerator for a record 37 consecutive hours! But the main indicator of success for the operators is luminosity, the measurement of the number of potential collisions in a given time period. On 29 June, peak luminosity (the number of potential collisions per second and per surface unit) exceeded 1034cm-2s-1. This number may not mean much to most of us, but it made the LHC operators very proud as it corresponds to the ultimate objective defined by those who originally designed this huge machine!

I've had a message from a friend in CERN. The 750 GeV bumps have disappeared, they were simply noise. Embarrassing, he says.

New particle hopes fade as LHC data 'bump' disappears

Hopes for the imminent discovery of a particle that might fundamentally change our understanding of the Universe have been put on hold.

Results from the Large Hadron Collider show that a "bump" in the machine's data, previously rumoured to represent a new particle, has gone away.

The discovery of new particles, which could trigger a paradigm shift in physics, may still be years away.

All the latest LHC results are being discussed at a conference in Chicago.
