Unexpected data from the Large Hadron Collider suggest the collisions may be producing a new type of matter

Collisions between protons and lead ions at the Large Hadron Collider (LHC) have produced surprising behavior in some of the particles created by the collisions. The new observation suggests the collisions may have produced a new type of matter known as color-glass condensate. When beams of particles crash into each other at high speeds, the collisions yield hundreds of new particles, most of which fly away from the collision point at close to the speed of light. However, the Compact Muon Solenoid (CMS) team at the LHC found that in a sample of 2 million lead-proton collisions, some pairs of particles flew away from each other with their respective directions correlated. "Somehow they fly at the same direction even though it's not clear how they can communicate their direction with one another. That has surprised many people, including us," says MIT physics professor Gunther Roland, whose group led the analysis of the collision data along with Wei Li, a former MIT postdoc who is now an assistant professor at Rice University. A paper describing the unexpected findings will appear in an upcoming issue of the journal Physical Review B and is now available on arXiv. The MIT heavy-ion group, which includes Roland and MIT physics professors Bolek Wyslouch and Wit Busza, saw the same distinctive pattern in proton-proton collisions about two years ago. The same flight pattern is also seen when ions of lead or other heavy metals, such as gold and copper, collide with each other. Those heavy-ion collisions produce a wave of quark gluon plasma, the hot soup of particles that existed for the first few millionths of a second after the Big Bang. In the collider, this wave sweeps some of the resulting particles in the same direction, accounting for the correlation in their flight paths. It has been theorized that proton-proton collisions may produce a liquid-like wave of gluons, known as color-glass condensate. This dense swarm of gluons may also produce the unusual collision pattern seen in proton-lead collisions, says Raju Venugopalan, a senior scientist at Brookhaven National Laboratory, who was not involved in the current research. Venugopalan and his former student Kevin Dusling theorized the existence of color-glass condensate shortly before the particle direction correlation was seen in proton-proton collisions. While protons at normal energy levels consist of three quarks, they tend to gain an accompanying cluster of gluons at higher energy levels. These gluons exist as both particles and waves, and their wave functions can be correlated with each other. This "quantum entanglement" explains how the particles that fly away from the collision can share information such as direction of flight path, Venugopalan says. The correlation is "a very tiny effect, but it's pointing to something very fundamental about how quarks and gluons are arranged spatially within a proton," he says. The CMS researchers originally set out to use the lead-proton collisions as a "reference system" for comparison with lead-lead collisions. "You don't expect quark gluon plasma effects" with lead-proton collisions, Roland says. "It was supposed to be sort of a reference run—a run in which you can study background effects and then subtract them from the effects that you see in lead-lead collisions." That run lasted only four hours, but in January, the CMS collaboration plans to do several weeks of lead-proton collisions, which should allow them to establish whether the collisions really are producing a liquid, Roland says. This should help narrow down the possible explanations and determine if the effects seen in proton-proton, lead-proton and lead-lead collisions are related.

Scientific Paper:
[1210.5482] Observation of long-range near-side angular correlations in proton-lead collisions at the LHC

i remember seeing something in ted talks about a missing element that theoretically exists, but not discovered. i wonder if this is it?

while i get and have a general understanding of wtf is going on here it's crazy to me that in 10-50 years we'll end up with some type of commercial application of this shyt right here that will be taken fore granted ...mark my words.

This experiment needs to be made public asap. Every detail of the LHC...I been studying it since I read angels and demons, maybe 7 yrs ago

what's not "public" about it?

 

[NkrumahWasRight Is Wrong]

what's not "public" about it?

Who can see it?

 

[daze23]

Who can see it?

what do you mean?

they're not gonna let 'the public' into the actual facilities for obvious reasons. but there's (civilian) scientists from all over the world that study the data, and then they publish their results if they find anything

all conspiracies aside, it's hardly some kind of 'top-secret' experiment

Cameras live streaming it. If its light speed it should be phenomenal to see.

Do u know how much money is involved?

Swiss bank accounts, govt grants, private donations, black budget projects based on extensions..patents..inventions..not to mention the actual value of the resulting matter...

there's nothing to "see" with a camera. all there is a shyt-ton of raw data (aka a bunch of numbers) collected by very sensitive detectors. if I had access to that data, I wouldn't even know what to look for

honestly for someone that claims to have studied this...

[NkrumahWasRight Is Wrong]

Believe what you see and hear, do what you gotta do

 

[Fillerguy]

how the fukk you live stream protons moving at near light speeds

 

[NkrumahWasRight Is Wrong]

how the fukk you live stream protons more a near light speeds

If its unobservable its not scientifically valid.

Ill wait on the peer reviewed articles and I suggest everyone else do the same unless everyone can see the experiment theres no point (edit: in the meantime).

Its like oh look this is a picture of our universe, but its from inside of it so what...thats like something living on the moon independent of knowledge off the Earth, looking at the blue sphere amd deducing its something more than a blue sphere...which its not.

Until they invent something that can see it the lhc itself is billions of dollars worth of potential chaos worse than teslas particle beam stuff.
