	Particle accelerator - Wikipedia, the free encyclopedia
		In early particle accelerators a Cockcroft-Walton voltage multiplier was responsible for voltage multiplying.
		As the particles approach the speed of light the switching rate of the electric fields becomes so high that they operate at microwave frequencies, and so RF cavity resonators are used in higher energy machines instead of simple plates.
		Depending on the energy and the particle being accelerated, circular accelerators suffer a disadvantage in that the particles emit synchrotron radiation.

	Elementary particle - Wikipedia, the free encyclopedia
		In particle physics, an elementary particle is a particle of which other, larger particles are composed.
		There are likely to be hypothetical elementary particles not described by the Standard Model, such as the graviton, the particle that would carry the gravitational force or the sparticles, supersymmetric partners of the ordinary particles.
		According to string theorists, each kind of fundamental particle corresponds to a different resonant vibrational pattern of a fundamental string (strings are constantly vibrating in standing wave patterns, similar to the way that quantized orbits of electrons in the Bohr model vibrate in standing wave patterns).

		Particles erupt from the collision point of two relativistic (100GeV) gold ions in the STAR detector of the Relativistic Heavy Ion Collider.
		One of the major activities in theoretical particle physics is the attempt to better understand the standard model and its tests.
		This divide of efforts in particle physics is reflected in the names of categories on the preprint archive [1]: hep-th (theory), hep-ph (phenomenology), hep-ex (experiments), hep-lat (lattice gauge theory).

		At the moment, the particle physics world is watching as Fermilab struggles to fulfil the promise of Run II at the Tevatron; and CERN's current LHC budget and schedule challenges have strong implications for the future of every physics laboratory.
		To achieve the kind of future that particle physicists everywhere would like for their field, the Standard Model of Physics Communication will have to change.
		As the early American experimental physicist Benjamin Franklin told his colonial colleagues in 1776: "We must all hang together, or assuredly we shall hang separately." The Quark Wars are over.

	Particle physicists discover new meson (May 2005) - News - PhysicsWeb
		Physicists may have discovered the first "hybrid meson" at the KEK laboratory in Japan.
		The properties of the decay have led the Belle team to believe that it is not a standard quark-antiquark particle but may be a hybrid meson containing a charm quark, a charm antiquark and a gluon.
		These include several particles called pentaquarks (which may or may not exist) that contain five quarks, a particle called the X(3872) that appears to be made of four quarks, and another meson called the Ds(2317) that does not behave as predicted.

	LHC@home - Why do physicists need accelerators?
		Some of these particles, such as the electron, are stable and form normal matter.
		The enormous concentration of energy that can be reached in collisions between particles such as electrons or protons in an accelerator can recreate the conditions of the early universe, and generate particles like the Higgs boson for a fraction of a second, before such particles decay into more ordinary ones.
		It is the tell-tale traces left by these more ordinary particles that the physicists capture in huge detectors, placed around collision points on the accelerator.

	Problems for the Standard Model
		The only fundamental force not included in the Standard Model of particle physics is gravity: Physicists have been unable to construct a consistent quantum theory of gravity although string theory holds some promise.
		Of these particles, only the electrons are stable; the other charged leptons, which are heavier, decay in a small fraction of a second.
		The exchange of vector gauge bosons generates the particle forces: Passing virtual photons between charged particles yields the electromagnetic forces, exchanging virtual W's and Z's between quarks and leptons produces the weak subnuclear forces, and rapidly emission between gluons themselves and quarks creates the strong interactions.

	New Scientist Breaking News - Particle physicists rescue rare vinyl recordings
		During construction of the lab's five-storey tall ATLAS instrument, which is soon to be used to search for an elusive particle called the Higgs boson, a precise optical system was used to align the silicon detectors used to monitor the trajectory of subatomic particles.
		By modifying the instrument and passing it above the grooves used to store audio on vinyl, the researchers were able to visually record their position to an accuracy of a one thousandth of a millimetre.
		Furthermore, algorithms used to strip away background noise from particle data proved an effective way to clean up scratches and other flaws on the vinyl.
