Weak force

Astronomy WaznWeber bar

Weak force- the second weakest of the four fundamental forces, with a very short range; it affects all matter particles, but not force-carrying particles ...

 


weak force: One of the four forces of nature; the weak force is responsible for some forms of radioactive decay.
west point: The point on the western horizon exactly halfway between the north point and the south point; exactly west.

ELECTROWEAK FORCE - Unified force combining the electromagnetic force and weak nuclear forces. The unification of these two forces was proposed in the 1960s by Sheldon Glashow, Steven Weinberg and Abdus Salam.

Electroweak Force
(a) The combination of the electromagnetic force and the weak nuclear force which takes place at high energy.
(b) A unification of electromagnetism and the weak nuclear force.

weak force The nuclear force involved in radioactive decay. The weak force is characterized by the slow rate of certain nuclear reactions such as the decay of the neutron, which occur with a half-life of 11 min.

Weak Force
The force that governs the change of one kind of elementary particle into another. This force is associated with radioactive processes that involve neutrons.

weak force - (n.)
One of the four fundamental forces of nature, weaker than the strong force and the electromagnetic force. It is important only in the decay of certain elementary particles.
weight - (n.) ...

Weak Force - This causes Beta decay (the conversion of a neutron to a proton, an electron and an antineutrino) and various particles (the "strange" ones) are formed by strong interactions but decay via weak interactions (that's what's strange about ...

A unit of charge defined as the charge which exerts a force of 1 dyne on a charge of equal magnitude at a distance of 1 cm. [H76]
Electroweak Force ...

Two types actually exist, the "strong force" which holds nuclei together, and the "weak force" which determines the ratio between the numbers of protons and neutrons.

At this point, there are now three forces in existence - Gravity, Strong Nuclear Force and the Electro-Weak force. This last is a combination of two forces, which, like the GUT, is sort of strange.

In More Precisely 16-1 we noted that the behavior of all matter in the universe is ruled by just three fundamental forces"gravity, the electroweak force (the unification of the electromagnetic and weak forces), and the strong (nuclear) force.

The electromagnetic and the weak forces are now understood to be different facets of a single underlying force that is described by the electroweak theory.

Researchers speculate that this is the reason why investigation through the weak force, the strong force, and the electromagnetic force have not hinted at the possibility of extra dimensions.

Actually two kinds of force are active in the nucleus, known simply as the "strong force" and the "weak force, ...

Basically, around 1980 or so, theoretical physicists managed to unify the electromagnetic and weak forces into the electroweak force. This resulted in, among other things, the standard model.

Gravity is the only one of the four fundamental forces of nature that stubbornly refuses to be quantised (the other three: Electromagnetism, the Strong Force, and the Weak Force, can be quantised).

Neutrinos interact primarily through the weak force. The discovery of neutrino flavor oscillations implies that neutrinos have mass.

Because WIMPs may only interact through gravitational and weak forces, they are extremely difficult to detect. However, there are many experiments underway to attempt to detect WIMPs both directly and indirectly.

These are unknown, theoretical particles that interact through gravity and the weak force (which causes radioactive decay). The Large Hadron Collider (LHC) is searching for evidence of their existence, and theory suggests they fit the bill.

(see Super-Kamiokande and Sudbury Neutrino Observatory) have shown it to be nonzero. Since it is an electrically neutral lepton, the neutrino interacts neither by way of the strong nor the electromagnetic force, but only through the weak force and ...

The substances iron, hydrogen, sulfur, carbon, nitrogen and oxygen, as well as the fundamental interactions of gravity, electromagnetism, weak force and strong force, are just as prevalent within the stars and planets as they are on Earth.
