The detection is detailed in a new study published in the journal Physical review letters.

Exotic 'X' particles first detected in quark gluon plasma 01 |  TweakTown.com

Immediately after the Big Bang, the universe was an extremely hot, concentrated plasma of elementary particles known as quarks and gluons, the precursor particles to protons and neutrons that make up all matter as we know it. In the first split second of existence, before the universe expanded, these quarks and gluons briefly united in various combinations known as “X” particles with unknown structures and properties.

Physicists have theorized that their creation would be possible in particle accelerators, and now physicists from MIT’s Laboratory for Nuclear Science have found evidence for X-particles in experiments conducted by the Large Hadron Collider (LHC) at CERN, European Organization for Nuclear Research, based in near Geneva, Switzerland. From 13 billion heavy ion collisions, the team identified about 100 X particles, known as the X (3872) type, with 3872 referring to the estimated mass of the particle.

“This is just the beginning of the story. We have shown that we can find a signal. In the next few years we will use the quark gluon plasma to probe the internal structure of the X particle, which may change our view of what kind. of material the universe should produce, “said lead author Yen-Jie Lee, a class of 1958 career development associate professor of physics at MIT.
