This is exactly when the external momentum can create physical particles.

If the particles created are not stable, the decay process can continue.

It is only this smaller amount of energy that can be used to create particles like the Higgs.

However, these operators literally create and annihilate particles of a given quantum state.

Her research concerns neutrinos, elementary particles created from nuclear reactions like those happening in the sun.

The long neutrons were machines for creating particles in the macrosphere.

The subatomic particles created by collisions will allow scientists to analyze the nature of matter and energy.

Pellet are small particles typically created by compressing an original material.

Even worse, a sudden energy fluctuation could create dangerous particles or miniature black holes.

When an atom is sent through this accelerator, it slams into a target, creating particles.
