How do we know about the variety of elementary particles?

Slowly but surely revealing the theoretically predicted particles…

With their own hands physicists allow new species of particles that do not exist in substances to be born. The birth occurs when particle beams collide with either a target or each other at purposely built particle accelerators. Although most of the resulting particles do not live long, their lifetime is high enough for scientists to register them with help of special tools called detectors of elementary particles. These detectors work as magnifying lenses transmitting information about the produced particles to computer’s memory. Here is a photo that can give an idea of ​​the size and complexity of the particle detector ATLAS built for the Large Hadron Collider (LHC). In addition, there are three more large detectors placed at the LHC’s accelerating ring: the CMS, LHCb and ALICE.

Today, the power of large international collaborations is necessary to carry out experiments studying elementary particles.
