The particle was predicted to exist back in the 1960s but now scientists at the LHC have confirmed its existence.

The discovery, which amounts to a new form of matter, was made by the Hadron Collider's LHCb experiment.
"There is quite a history with pentaquarks, which is also why we were very careful in putting this paper forward," Patrick Koppenburg, physics co-ordinator for LHCb at Cern, told BBC News.
"It's just the word 'pentaquark' which seems to be cursed somehow because there have been many discoveries that were then superseded by new results that showed that previous ones were actually fluctuations and not real signals."

"We have examined all possibilities for these signals, and conclude that they can only be explained by pentaquark states," said LHCb physicist Tomasz Skwarnicki of Syracuse University, US

It never ceases to amaze me how we go deeper and deeper into the world of the small and still find more and more stuff.

And it is just a year ago that CERN announced the Tetra-Quark, but I think they chose another name for it!

I read stuff like this and think... my job sucks.

It’s pretty fascinating, but does it do anything?

Serious question, anyone know of any practical applications for this or the Higgs?

Pentaquark, tetraquark, captain quark...I can't keep up anymore.

Soon enough the standard model will need it's own 'periodic table'.

Here is the blurb from Cern.
press.web.cern.ch...


Geneva, 14 July 2015. 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.

LHCb researchers looked for pentaquark states by examining the decay of a baryon known as Λb (Lambda b) into three other particles, a J/ψ- (J-psi), a proton and a charged kaon. Studying the spectrum of masses of the J/ψ and the proton revealed that intermediate states were sometimes involved in their production. These have been named Pc(4450)+ and Pc(4380)+, the former being clearly visible as a peak in the data, with the latter being required to describe the data fully.

“Benefitting from the large data set provided by the LHC, and the excellent precision of our detector, we have examined all possibilities for these signals, and conclude that they can only be explained by pentaquark states”, says LHCb physicist Tomasz Skwarnicki of Syracuse University.

"More precisely the states must be formed of two up quarks, one down quark, one charm quark and one anti-charm quark.”

Earlier experiments that have searched for pentaquarks have proved inconclusive. Where the LHCb experiment differs is that it has been able to look for pentaquarks from many perspectives, with all pointing to the same conclusion. It’s as if the previous searches were looking for silhouettes in the dark, whereas LHCb conducted the search with the lights on, and from all angles. The next step in the analysis will be to study how the quarks are bound together within the pentaquarks.

“The quarks could be tightly bound,” said LHCb physicist Liming Zhang of Tsinghua University, “or they could be loosely bound in a sort of meson-baryon molecule, in which the meson and baryon feel a residual strong force similar to the one binding protons and neutrons to form nuclei.”

was any scientist wearing a vaguely inappropriate shirt SJWs can get upset and cry over?
If not, then this, like many other great scientific accomplishments, will fall into relative obscurity.

Yes , it proves the hypothesis from the 1960s that it should exist.

“The pentaquark is not just any new particle,” said Guy Wilkinson from the LHCb in a press release. “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.”

Each small step takes us closer to new physics , new physics will take us closer to new star systems ... eventually.

Major news, thanks. Since more than one form of quark was discovered I've thought and vocalized that the quark is not the ultimate building block of matter, that's yet to be found, or it could just be stylized energy around a non-point, kicked up to full steam by non-point size gravity and connected to others of its kind by mirrorization effects.

Isn't that like asking "what are the practical applications for the individual iron atoms in this building's steel beams"?

They are just going to find smaller and smaller and smaller particles until they are so small we don't have a physical way to detect or measure them anymore, so they think there is nothing more to find, and their models will be incomplete.

I don't think any of their "models" contain the possibility of an infinite division of the whole. They have already shot their selves in the foot by giving every possible particle a name, knowing not that there is only ONE primal energy that can be divided infinitely. So their book of names better be infinitely large.

Imagine you are a lucid dreaming scientist, and you decided to study the material objects in your dream to see what they are made of. What do you think you will find?

You will find an infinite mind.

This is amazing... I've always thought that instead of looking out at the universe to discover our beginnings we need to look within.
Every time we find what we think is the end of the line in regards to what is the smallest thing.. something else pops up to blow our theories out of the water.
looks like the lhc budget and experiments are well justified.

This blog has an interesting explanation on how information is stored and exchanged in the universe. Quarks, Gluons are like sockets in the internet.
aaronsreality.blogspot.fr...

Quarks are just the interaction between Gluons and the way information is exchanged in the universe. You can't break quarks into smaller particles. There's an interesting comparison between the fetch/decode/read/write cycles of CPU's and interchange of information between particles (spin counters). But a modern CPU can actually have hundreds of instructions in various stages of completion.

There are many good reasons to believe we have already discovered the smallest units of matter. For a start QM tells us that energy is quantized which means there are no truly continuous or fractal energy states in nature. Also, if you could divide energy up into infinitely small units, then nearly all particles would look different, but in fact all fundamental particles in existence have the exact same structure (eg electrons). And finally, even if you attempt to separate a pair of quarks you'll find it impossible, the energy you put into breaking the bond will produce a new quark pair, it's literally impossible to break them apart.

Interesting discovery.
BTW keep the funding coming and we will keep finding new particles.

Well... Scientists are calling it a "new" particle... but it's actually just another mosaic of already-discovered quarks.



Pentaquarks are just structures made of five quarks (by comparison, normal matter has three quarks).
