What is hadronization process?
Hadronization (or hadronisation) is the process of the formation of hadrons out of quarks and gluons. There are two main branches of hadronization: quark-gluon plasma (QGP) transformation and colour string decay into hadrons.
What is a QCD jet?
A jet is a narrow cone of hadrons and other particles produced by the hadronization of a quark or gluon in a particle physics or heavy ion experiment. Particles carrying a color charge, such as quarks, cannot exist in free form because of QCD confinement which only allows for colorless states.
What is hard scattering?
“Hard” means large. momentum transfer- either a. violent scatter or creation of a. system of large mass. A “Cartoon” of a hard parton `scattering’
What is confinement particle physics?
In quantum chromodynamics (QCD), color confinement, often simply called confinement, is the phenomenon that color-charged particles (such as quarks and gluons) cannot be isolated, and therefore cannot be directly observed in normal conditions below the Hagedorn temperature of approximately 2 terakelvin (corresponding …
What is jet in high-energy physics?
Jets are the experimental signatures of quarks and gluons produced in high-energy processes such as head-on proton-proton collisions.
What is the difference between ionized plasma and quark-gluon plasma?
Plasma is the fourth state of matter. It is formed when gases are heated to extreme temperatures where they loose electrons and form ions. On the other hand quark gluon plasma is not a state of matter. Infact in quark gluon plasma quarks and gluons are supposed to be found as individual particles and not in pairs.
How are gluons created?
When protons and neutrons are accelerated to extreme speeds, the gluons inside them multiply. At high speeds the proton’s energy increases and gluons split into daughter pairs, each with slightly less energy than the original. The new gluons, in turn, create more daughter gluons with even less energy.
