A typical example is offered by a free massive particle and, in this case, the constant has the value 1/m.

The photon in this model becomes a massive particle at low temperatures.

One of the first ever boosted massive particle candidates.

The spectrum of the model consists of a single massive particle.

These massive particles are also seen to decay into 2-3 particles.

Rather counterintuitively, more massive particles are, in general, more difficult to produce.

Because electrons are so much smaller than atoms, there must be other, more massive particles in the atom.

The term massive particle refers to particles which have non-zero rest mass.

Quarks are massive particles, and therefore are also subject to gravity.

In particular, massive particles can interfere and therefore diffract.

Massive particles tore through the neural nets which comprised her awareness.

Substituting this into the equation for a massive particle gives:

The quarks, which were massive particles that carried fractional electric charges.

"Weakly interactive massive particle," the postdoc who'd been talking to him about the missing mass said.

The four-momentum for a massive particle is given by:

It is the conversion of massless particles into one or more massive particles.

Other thermodynamic parameters may be derived analogously to the case for massive particles.

The radiation field is not, however in equilibrium and is being entirely driven by the presence of the massive particles.

For example, LTE is usually applied only to massive particles.

There are elementary particles that spontaneously decay into less massive particles.

It defines the non-relativistic, non-quantum mechanical limit for massive particles.

For a massive particle, the components of the four-velocity satisfy the following equation:

Models of supersymmetry involve new, highly massive particles.

But muons are 200 times as heavy, the better to interact with the relatively massive particles predicted by supersymmetry.

The winner must then prove that the mass of the least massive particle of the force field predicted by the theory is strictly positive.
