This weak charge is predicted by the Standard Model to be about -0.989 for neutrons and about + 0.071 for protons (+) and electrons (-), as measured in elementary charges.

Only quarks have a smaller charge, being a third or two-thirds of the elementary charge. The elementary charge of the proton is 1.602192 x 10^–19 coulombs (C).

Since the weak charge of the proton is precisely predicted by the Standard Model, which is a well-tested theoretical framework that describes the elementary particles and the details of how they ...

The Large Hadron Collider (LHC) has begun its first-ever collisions of oxygen ions, in the latest attempt to understand the ...

The proton can contain pairs of elementary particles known as strange quarks. The contribution of these particles to the proton's electric-charge distribution and magnetic moment has been determined.

Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces, and pressures inside a subatomic particle for the first time.

Protons are made of two up quarks and one down quark, while neutrons contain two down quarks and one up quark. (Image credit: MichaelTaylor | Shutterstock ) Elementary particles are the smallest ...

The electric charge radius of the proton was first measured in 1955, in experiments that involved high-speed electrons being shot at a target of hydrogen atoms 3.

The charge of each electron has the same magnitude as a proton, defined as one elementary electric charge (1 e). The number and position of electrons are shown on the periodic table by the element ...

Protons are no one-trick ponies. Although famous for their positive electric charge, the particles also carry an analogous, lesser-known charge, called the weak charge. Now, physicists have made ...

NEWPORT NEWS, VA, Sept. 17, 2013 – Researchers have made the first experimental determination of the weak charge of the proton in research carried out at the Department of Energy's Thomas ...
