Large Hadron Collider luminosity upgrade project moving to next phase
After a four year long design study the project is now moving into its second phase, which will see the development of industrial prototypes for various parts of the accelerator. Luminosity is a crucial indicator of performance for an accelerator. It is proportional to the number of particles colliding within a defined amount of time. Since discoveries in particle physics rely on statistics, the greater the number of collisions, the more chances physicists have to see a particle or process that they have not seen before. The High-Luminosity LHC will increase the luminosity by a factor of 10, delivering 10 times more collisions than the LHC would do over the same period of time.

...The increase in luminosity will mean physicists will be able to study new phenomena discovered by the LHC, such as the Higgs boson, in more detail. The High-Luminosity LHC will produce 15 million Higgs bosons per year compared to the 1.2 million in total created at the LHC between 2011 and 2012.

After the successful restart of the Large Hadron Collider and its first months of data taking with proton collisions at a new energy frontier, the LHC is moving to a new phase, with the first lead-ion collisions of season 2 at an energy about twice as high as that of any previous collider experiment. Following a period of intense activity to re-configure the LHC and its chain of accelerators for heavy ion beams, CERN’s accelerator specialists put the beams into collision for the first time in the early morning of 17 November 2015 and ‘stable beams’ were declared at 10.59 a.m. today, marking the start of a one-month run with positively charged lead ions: lead atoms stripped of electrons. The four large LHC experiments will all take data over this campaign, including LHCb, which will record this kind of collision for the first time. Colliding lead ions allows the LHC experiments to study a state of matter that existed shortly after the big bang, reaching a temperature of several trillion degrees.

In reading the linked article I wondered what the NASA equivalent would be, Did you know that the next generation space telescope is being finished now? Its named after James Webb a NASA administrator during the Apollo days. A NASA goal is to observe some of what CERN is attempting to replicate. JWST should give us some pretty exciting images after its scheduled launch in 2018.

Here's the NASA link http://jwst.nasa.gov/firstlight.html NASA's new space telescope brings an excitement to the CERN element, The combined information may be a real eye opener to cosmic origins.

I notice Taylor that the article says that just after the big bang a "hot soup" of particles formed. What with Darwin's warm puddle and primeval soups we are edging closer to a scientific formulation of origins.
The soup dun it!

CERN LHC Update: Researchers See Tantalizing Hints Of New Particle Heavier Than The Higgs Boson

Scientists have spent years testing and probing the so-called Standard Model of particle physics, looking for chinks in its armor that may hint at some hitherto undiscovered realm of reality. On Tuesday, two teams of physicists working independently at CERN’s Large Hadron Collider (LHC) reported that they may have just seen traces of a new fundamental particle, which if confirmed, would break the model that has governed our understanding of the cosmos for the past quarter century.

...Here’s the kicker: Since the Higgs boson was the last missing piece from the Standard Model, the only way another, more massive particle can be incorporated is by discarding the Standard Model and opening an entirely new chapter in the field of particle physics.

“The more nonstandard the better,” Joe Lykken, the director of research at the Fermi National Accelerator Laboratory and a member of one of the CERN teams, reportedly said. “It will give people a lot to think about.”

***We interrupt this broadcast to bring you a special news bulletin.***
At around 5:30 am on Friday 29 April 2016, a small beech marten found its way onto a large, open-air electrical transformer situated above ground at CERN, causing a short circuit and cutting the power to part of the Large Hadron Collider (LHC).

The concerned part of the LHC stopped immediately and safely. Since then the entire machine has remained in standby mode.

Stay tuned for the next "few weeks, or possibly even within days", this could get really......... (Also see post from 12/16/15 above.)
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

...This really does look like a new particle, and if it is, there is suddenly an enormous crack at the very heart of high-energy physics.

The signal is one of the simplest you can imagine: it represents two high energy photons emerging from the decay of a subatomic particle created in a proton-proton collision. 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 in the auditorium. People look around, astonished, trying to confirm that their own reactions are reflected in what they see in their colleagues’ faces. If the observations are confirmed, it will be revolutionary. This could mean nothing less than the fall of the Standard Model of particle physics (SM), which has passed every experimental test thrown at it since it was first put together over four decades ago.

New particle hopes fade as LHC data 'bump' disappears

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.

...David Charlton of Birmingham University, leader of the Atlas experiment at the LHC, told BBC News that everyone working on the project was disappointed. "There was a lot of excitement when we started to collect data. But in the [latest results] we see no sign of a bump, there's nothing. It is a pity because it would have been a really fantastic thing if there had been a new particle."
