Technicolor models use a new force of nature to generate particle masses.

To put matters in terms of forces, the accelerations are multiplied by the particle mass:

In these, gluons that bind quarks together confer most of the particle mass.

In this expression m the particle mass and h Planck's constant.

He also realizes that the particle mass is similar to the one of hydrogen particle.

Cigarette smoke accounts for 1 to 1.3 percent of the fine particle mass in the atmosphere there, researchers have found.

The same unattractive messiness turns up in the particle masses.

Physicists in making this choice decided that properties other than particle mass should control their classification.

The strangeness quantum number S (not to be confused with spin) was noticed to go up and down along with particle mass.

The electron-volt is used by scientists as a unit of particle mass.
