Update:

First physics experiment at HIE-ISOLDE begins

“It’s a major breakthrough. This is the result of eight years of development and manufacturing. This would not have been possible without the dedication of the technical staff at CERN. But what makes us most proud isn’t that we built a machine, but that we have attracted enthusiastic users to do forefront physics. We are looking forward to this exciting high intensity period,” says Yacine Kadi , leader of the HIE-ISOLDE project.


Update for scientists:

ICE-DIP project comes to a close with workshop held at CERN

ICE-DIP brings together CERN, Intel and universities to offer training to five PhD students in advanced information and communication technologies (ICT).
The focus of the project, which launched in 2013, has been the development of next-generation techniques for acquiring and processing data that are relevant for the trigger and data-acquisition systems of the LHC experiments. The developments made by the ICE-DIP researchers are of great interest for CERN’s future computing facility upgrades, other research laboratories and, potentially, other business sectors too.

Update:

Great expectations from fewer collisions

Usually, the motto of the LHC is ‘maximum luminosity’ (in other words, as many collisions as possible).
But last week, the LHC ignored its motto, and performed special runs at very low luminosity for the TOTEM and ATLAS/ALFA experiments.
This is because scientists want to study a particular type of interaction, called “elastic scattering”. Elastic scattering is when two protons survive their encounter in the detector intact, without colliding head-on, so they don’t create new particles and only slightly change their direction. In normal LHC runs, this interaction is not observable, as the protons are more likely to crash into each other and create new particles.

One of the most fascinating physics goals of TOTEM is to get information on the probability that two protons pass completely through each other without interfering.

I had to transfer to Kansas City to get some real data from CERN. Since they say Kansas City has an optical fiber network, people residing there can get real data to run in vLHC@home and not simulated data. So I joined the Kansas City team and now I am getting jobs from CERN saluting me as a Kansas City citizen. But I still live near Milano, no teleportation so far.

Do you mean this project?
https://cernkcchallenge.github.io/CernKCChallenge/
Finally, to participate in the CERN+KC Challenge, you must join “Team Kansas City!” The special jobs for fiber users are currently limited to participants on Team Kansas City, since this is a limited test. To join, go to the Team Kansas City page, log in to your account, and click “Join this team.”.

No teleportation so far:)

Scientists use laser to unlock the secrets of antimatter


Scientists have succeeded in shining light on trapped antimatter atoms to detect whether they behave differently to regular atoms. This is the first time physicists have managed to control antimatter long enough to directly measure its behaviour and compare it.

The achievement is the result of two decades of work and opens up new ways of studying antimatter. “This is the reason CERN was created,” said Jeffrey Hangst, spokesperson for Cern’s Alpha experiment in Switzerland and professor at Aarrhus University in Denmark.

The January/February issue of CERN Courier is all dedicated to gravitation after the detection of gravitational waves by LIGO. It also explains the possible role of gravitational waves in the context of the various quantum gravity theories and, of course, strings theory. I am going to follow an online course on gravitation offered by Diderot University of Paris in the hope of understanding something of all, often conflicting, theories of gravitation covered in the CERN Courier articles.

So what about the possible relationship between gravity and Electromagnetism?

For now a couple of other things earlier being mentioned does not seem to fit in with the rest of it either, so definitely still something is still missing.

Einstein tried vainly to unify gravity and EM in his Unified Field Theory. But he forgot nuclear forces, described by the Standard model. Now many people try to achieve what he did not succeed in achieving. Good luck to them.

I think the danger with CERN and the LHC, is the many reputations that will be broken, if no evidence for super symmetry particles are discovered.....

As a physicist, I am not caring for my reputation. I can learn from my mistakes, as Einstein has done.Carlo Revelli has made a list of Einstein's mistakes. They all produced some advances.

LHC double heavy particle to shine light on strong force


Scientists have detected a new particle at the Large Hadron Collider at Cern.

The discovery will help researchers learn more about the so-called "strong force" which holds the centres of atoms together.

The existence of the new particle was theoretically predicted but this is the first time it has been identified.

The details of the Xi-cc++ particle were presented at a high-energy physics conference in Venice.

Good!

Ξcc++ or Xicc++
Weird name for a particle.
Since it's a baryon shouldn't it have a name ending with -on?
Like proton and neutron.

The name says it has 2 charm quarks and a double positive charge. The proton has charge 1 and the neutron has charge zero.

Another way of defining a Joule is that it is about the amount of energy used in each heartbeat...

Luckily our hearts performs better by one hundred times.

You need at least eat about 2000 kcal per day.
That's about 8 million Joules.
A heart rate at 1 per second is 86400 beats per day when not exercising .
About 100 J/s of energy are then distributed by the heart to our body.
Roughly 100 Watts.

At CERN they use electronvolt instead to measure energy and mass.
A heartbeat produces more then 6*10^20 Ev per heartbeat !

Scientists baffled: Universe shouldn't exist


Despite the organization’s $1.24 billion annual budget for 2017, the physicists at CERN, the European Organization for Nuclear Research, are being forced to admit failure in their latest effort to explain why any of us are here.

Indeed, why there’s even a “here” here at all.

“The universe should not actually exist,” said Christian Smorra, a physicist at CERN’s Baryon–Antibaryon Symmetry Experiment (BASE) collaboration.

CERN, founded in 1954, features a circular tunnel some 17 miles around that houses a particle accelerator, which uses peak energy of 14 trillion electron volts to speed particles to nearly the speed of light and allow them to collide. It is underneath Switzerland near its border with France.
