<p>97.78.165.202: </p> <hr /> <div>{{unreferenced|date=July 2009}}<br /> A '''relativistic particle''' is a particle which moves with a [[relativistic speed]]; that is, a [[speed]] comparable to the [[speed of light]]. This is achieved by [[photon]]s and by [[tachyon]]s to the extent that effects described by special relativity are able to describe those of such [[Elementary particle|particles]] themselves. Several approaches exist as a means of describing the motion of single and multiple relativistic particles, with a prominent example being postulations through [[dirac equation]]s of single particle motion.<br /> <br /> [[Mass]]ive particles are relativistic when their [[kinetic energy]] is comparable to or greater than the energy &lt;math&gt;mc^2&lt;/math&gt; corresponding to their [[rest mass]]. (This condition implies that their [[speed]] is close to the [[speed of light]].) Such relativistic particles are generated in [[particle accelerator]]s, and are naturally occurring in [[cosmic radiation]]. In [[astrophysics]], [[relativistic jet|jets]] of [[relativistic plasma]] are produced by the centers of [[active galaxy|active galaxies]] and [[quasar]]s.<br /> <br /> A charged relativistic particle crossing the interface of two media with different [[dielectric constant]]s emits [[transition radiation]]. This is exploited in the [[transition radiation detector]]s of high-velocity particles.<br /> <br /> ==See also==<br /> * [[Special relativity]]<br /> * [[Relativistic wave equations]]<br /> * [[Lorentz factor]]<br /> * [[Relativistic mass]]<br /> * [[Relativistic plasma]]<br /> * [[Relativistic jet]]<br /> * [[Relativistic beaming]]<br /> * [[List of plasma (physics) articles]]<br /> <br /> [[Category:Quantum mechanics]]<br /> [[Category:Special relativity]]<br /> [[Category:Accelerator physics]]<br /> <br /> <br /> {{relativity-stub}}</div>
