Specifically, they want to use machine learning to reconstruct
gluons.
Gluons are core particles that contain a lot of information, but are very difficult to see.
The hadronic matter within the tube has very high density and high temperature T [much greater than] [mu][c.sup.2], where [mu] is the pion mass, so that, following modern concepts it consists of point-like quarks and
gluons, rather than usual hadrons.
All hadrons, including protons, are composed of quarks and
gluons which are (currently) considered fundamental particles that feel the strong nuclear force.
The fourth lesson is entitled 'Particles' and considers the nature of matter and its components, electrons, quarks, photons and
gluons, but also explains why some physicists are unhappy with this 'standard model'.
In one and the same instant, by refusing Socratic formalism Priest's
gluons reinforce the widespread intuition that ingredients are relevant keys to material explication, even as they also challenge the same intuition with a fundamental particle that does and does not belong to a unified whole.
To remove the ultraviolet (UV) divergences in the quarks and
gluons perturbed interaction, we modify the propagator like:
Overrun with hungry leptons, sticky-fingered
gluons and massive bosons, Schrodinger's Cat is called in to get the pesky particles under control and back where they belong.
But take quantum physics - the world of exotically named particles like quarks and
gluons that make up the individual atoms we and the rest of the universe are made of.
Inside protons and neutrons that make up the colliding atomic nuclei are elementary particles called quarks, which are bound together tightly by other elementary particles called
gluons. Only under extreme conditions, such as collisions in which temperatures exceed by a million times those at the center of the sun, do quarks and
gluons pull apart to become the ultra-hot, frictionless perfect fluid known as quark-gluon plasma.

Gluons: Calorons Out of the Box
