The collaboration has observed a new kind of “pentaquark” and the first-ever pair of “tetraquarks”

The international LHCb collaboration at the Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of “pentaquark” and the first-ever pair of “tetraquarks”, which includes a new type of tetraquark. The findings, presented today at a CERN seminar, add three new exotic members to the growing list of new hadrons found at the LHC. They will help physicists better understand how quarks bind together into these composite particles.

Quarks are elementary particles and come in six flavours: up, down, charm, strange, top and bottom. They usually combine together in groups of twos and threes to form hadrons such as the protons and neutrons that make up atomic nuclei. More rarely, however, they can also combine into four-quark and five-quark particles, or “tetraquarks” and “pentaquarks”. These exotic hadrons were predicted by theorists at the same time as conventional hadrons, about six decades ago, but only relatively recently, in the past 20 years, have they been observed by LHCb and other experiments.

Good stuff. Thanks.

in Christ all things hold together

They dig down far enough they're going to come to the impassable and incomprehensible spiritual element of Christ that holds all things together. Their physical means won't be able to penetrate that.

It is possible that as infinitely vast our universe is the same applies to looking inward into matter. We are only seeing a minutia of how small it goes.

[rdl6989]

Agreed.

Everybody likes Quark's.

I have this fear that one of these days these collider/accelerator guys are going to blow us to atoms.

There’s a bunch of fanfics on 4chan saying that they already have torn space time and are now sending people back to alternative timelines.

Yes, even the "Doublemint Twins".

"Most of the exotic hadrons discovered in the past two decades are tetraquarks or pentaquarks containing a charm quark and a charm antiquark, with the remaining two or three quarks being an up, down or strange quark or their antiquarks. But in the past two years, LHCb has discovered different kinds of exotic hadrons. Two years ago, the collaboration discovered a tetraquark made up of two charm quarks and two charm antiquarks, and two “open-charm” tetraquarks consisting of a charm antiquark, an up quark, a down quark and a strange antiquark. And last year it found the first-ever instance of a “double open-charm” tetraquark with two charm quarks and an up and a down antiquark. Open charm means that the particle contains a charm quark without an equivalent antiquark."

Actually, Joe Biden said the exact same thing just last month...

ROTF!

That reminds me of Man in the High Castle.

Those two women have a lot of mileage on their faces.

Cornpop probably told him about this.

[rlmorel]

Heh, that was the first thing I thought of when I read that exchange...:)

More fun than the “THE WORLD IS GOING TO END FROM THE ACCIDENTAL BLACK HOLE THEY CREATE!”

Actually...no...those are kind of fun to read too!

That can’t be because the Planck constant is a hard limit.
