In particle physics, a jet is a shower of collimated particles generated by a highly energetic quark or gluon. In a lead-lead collision, jets must traverse through quark gluon plasma, altering their energy, track and consistency.

Forty years ago, in 1979, experiments at the DESY laboratory in Germany provided the first direct proof of the existence of gluons—the carriers of the strong force that "glue" quarks into protons, neutrons and other particles ...

Collisions of lead nuclei take place under extreme physical conditions. Their course can be described using a model which assumes that the transforming, extremely hot matter—the quark-gluon plasma—flows in the form of ...

Neutron stars are among the densest-known objects in the universe, withstanding pressures so great that one teaspoon of a star's material would equal about 15 times the weight of the moon. Yet as it turns out, protons—the ...

The leading theory about how the universe began is the Big Bang, which says that 14 billion years ago the universe existed as a singularity, a one-dimensional point, with a vast array of fundamental particles contained within ...
