An exotic particle is a kind of theoretical particle said to exist by some areas of modern physics whose alleged properties are extremely unusual. Physics (from the Greek, φυσικός (phusikos), natural, and φύσις (phusis), nature) is the science of nature in the broadest sense. ...
The best-known is probably the tachyon, a particle that only travels faster than light. A tachyon (from the Greek ταχύς {takhús}, meaning swift) is a hypothetical particle that travels at superluminal velocity. ...
Particles erupt from the collision point of two relativistic (100 GeV) gold ions in the STAR detector of the Relativistic Heavy Ion Collider.
Particlephysics is a branch of physics that studies the elementary constituents of matter and radiation, and the interactions between them.
Other important goals in particlephysics are the determination of the neutrino masses and the clarification of the existence of double beta decay of the proton.
An elementary particle is a particle with no measurable internal structure, that is, it is not a composite of other particles.
In quantum field theory, these are the particles which are created and annihilated by the field operators in the Lagrangian.
As a result, much of the theory of particlephysics applies to condensed matter physics as well; in particular, there is a whole zoo of field excitations, called quasi-particles, that can be created and explored.
