Thanks for that. And not making a black hole that ate the planet. ;)

CERN s LHCb experiment reports observation of exotic pentaquark particles

"Today, the LHCb experiment at CERN's Large Hadron Collider has reported the discovery of a class of particles known as pentaquarks. The collaboration has submitted a paper reporting these findings to the journal Physical Review Letters.

"The pentaquark is not just any new particle," said LHCb spokesperson Guy Wilkinson. "It represents a way to aggregate quarks, namely the fundamental constituents of ordinary protons and neutrons, in a pattern that has never been observed before in over fifty years of experimental searches. Studying its properties may allow us to understand better how ordinary matter, the protons and neutrons from which we're all made, is constituted."

Our understanding of the structure of matter was revolutionized in 1964 when American physicist, Murray Gell-Mann, proposed that a category of particles known as baryons, which includes protons and neutrons, are comprised of three fractionally charged objects called quarks, and that another category, mesons, are formed of quark-antiquark pairs. Gell-Mann was awarded the Nobel Prize in physics for this work in 1969. This quark model also allows the existence of other quark composite states, such as pentaquarks composed of four quarks and an antiquark. Until now, however, no conclusive evidence for pentaquarks had been seen."

CERN colliding lead ions at record energy using upgraded LHC
Nov. 26, 2015 - The upgraded collider is accelerting particles at a faster rate than in previous years.
Experiments to simulate matter states existing after the Big Bang are successfully underway at CERN's Large Hadron Collider near Geneva, Switzerland. CERN, the European Organization for Nuclear Research, announced Wednesday "stable beams" from lead-ion collisions begun November 17 were observed for the first time, beginning a one-month series of experiments with positively-charged lead ions, lead atoms with electrons removed.

CERN reported a successful start to experiments simulating conditions immediately after the Big Bang.​

The collision of lead ions is part of a study to approximate conditions immediately after the Big Bang, the prevailing model for the first seconds after the birth of the universe, when for a few milliseconds, matter was hot, dense and reached a temperature of several trillion degrees. "It is a tradition to collide ions over one month every year as part of our diverse research program at the LHC. This year, however, is special as we reach a new energy and will explore matter at an even earlier stage of our universe," said CERN Director-General Rolf Heuer.

This year's experiments, crashing individual protons together in a newly-reinforced chamber, are at a much higher rate of acceleration than in previous years. New behavior of particles is expected to be observed at these speeds, and new observations are anticipated.

CERN launches new accelerator to help boost data output
May 9, 2017, Scientists at the world's biggest atom smasher have inaugurated their newest particle accelerator, a key step toward churning out greater amounts of data that could help explain many lingering mysteries of the universe.
The European Organization for Nuclear Research, or CERN, announced Tuesday the completion of Linac 4, a 90-meter-long (295-foot-long) underground machine that took nearly a decade to build and will deliver proton beams for many experiments.

Linac 4 is CERN's largest accelerator developed since the 2008 startup of the Large Hadron Collider that helped confirm the Higgs boson particle five years ago.

Director-General Fabiola Gianotti said it's the first key element in a multi-year program to "increase the potential of the LHC experiments for discovering new physics and measuring the properties of the Higgs particle in more detail."
