Using Large Hadron Collider, a team of physicists has revealed the “littlest” quark-gluon plasma, a state of matter thought to have existed right at the birth of the universe, with fewer particles than previously thought possible.

The material was discovered by colliding protons with lead nuclei at high energy inside the supercollider’s Compact Muon Solenoid detector.

Researchers at the University of Kansas working with an international team at the Large Hadron Collider have dubbed the resulting plasma as the “littlest liquid.”

Researcher Quan Wang said that before the CMS experimental results, it had been thought the medium created in a proton on lead collisions would be too small to create a quark-gluon plasma.

Wang added that these collisions were being studied as a reference for collisions of two lead nuclei to explore the non-quark-gluon-plasma aspects of the collisions, noting that the analysis presented in this paper indicates, contrary to expectations, a quark-gluon plasma can be created in very asymmetric proton on lead collisions.

The researcher described quark-gluon plasma as a very hot and dense state of matter of unbound quarks and gluons — that is, not contained within individual nucleons.

Wang said such experiments might help scientists to better understand cosmic conditions in the instant following the Big Bang.

The study is published in APS Physics.

    One of these days, we might gain the knowledge about how to create the universe. We might also develop the technology to harness the power of fusion and have little suns in every major potion center to provide energy. We own so much to science yet so little is spent on expanding its implications compared to war systems. We must increase the number of scientists in the major decision nodes to give science/technology a dominant role in our systems instead of pecuniary interests.

        Who cares what happened at the start of time. Give us something useful like the ability to cancel gravity so that mankind can spread to the stars.

          Since when taking a high energy hitting something not produce heat Does heat melt ? Definitely it will turn anything bombarded into metal, This is a scientific break through for science on how to spend millions to melt metal with small particles at taxpayers expense ! Got a torch and I'll do it for a lot less, Or they can use their brains to try to catch up to me at cmae.ca where real energy of the universe will come from

            What's the point? There were no lead nuclei early in the universe's existence. However, the idea of quark-gluon plasmas is solid, if you pardon the pun.

              Beg pardon? Are you asking what the point of performing scientific experiments is? The point is to learn. Some folks seem to think that's a good idea. Go figure.

                He knows what he is talking about. He just doesn't know what Quan Wang is talking about.
