From page 161... ...
AMS. Alpha Mass Spectrometer experiment, a superconducting-magnet particle detector to be flown on the space station to search for cosmic rays of antimatter and dark matter.
|
From page 162... ...
Particle detector in which paths of charged particles are revealed by a trail of bubbles produced by the particles as they traverse a superheated liquid. Hydrogen, deuterium, helium.
|
From page 163... ...
In high-energy physics, the property of quarks and gluons analogous to electric charge that determines how the strong force acts between a quark and a gluon. Conservation law.
|
From page 164... ...
Drift chamber. Particle detector in which the passage of charged particles produces tracks of ionized gas.
|
From page 165... ...
Electroweak force or interaction. Force or interaction that unifies the electromagnetic force and the weak force.
|
From page 166... ...
Grand unified theory. Theory that unifies the electroweak force with the strong force into a single gauge theory.
|
From page 167... ...
Nucleon Decay Experiment, a 3,000-ton waterCerenkov proton decay and neutrino detector experiment (see Super Kamiokande)
|
From page 168... ...
Me V Mega electron volt, a unit of energy equal to 106 eV.
|
From page 169... ...
Baryon with a single positive unit of electric charge and a mass approximately 1,840 times that of the electron, made of two up quarks and one down quark. The proton is the nucleus of the simple hydrogen atom and a constituent of all atomic nuclei.
|
From page 170... ...
A 1,000-ton heavy-water Cerenkov detector under construction in a mine near Sudbury, Ontario, 6,800 feet below ground. SNO is designed to detect neutrinos produced by fusion reactions in the Sun.

From page 171... ...
Theory that summarizes the present picture of the field of elementary-particle physics. It includes three generations of quarks and leptons, the electroweak theory of weak and electromagnetic forces, and the quantum chromodynamic theory of the strong force.
|
From page 172... ...
WIMPs. Weakly interacting massive particles, a class of hypothetical particles thought to be a candidate for dark matter.
|
From page 173... ...
Z boson. Particle that carries the neutral weak force.
