As cosmic ray particles penetrate our atmosphere, they collide with air molecules and produce new high-energy particles. These particles, in turn, are involved in further collisions. The whole process is known as an air shower. ...

Jets are the experimental signatures of quarks and gluons produced in high-energy processes such as head-on proton-proton collisions. As quarks and gluons have a net colour charge and cannot exist freely due to colour-confinement, ...
