* Photons: Photons are not particles in the traditional sense, as they do not have mass and do not occupy space. Instead, they are quanta of light and other electromagnetic radiation.

* Gravitons: Gravitons are hypothetical particles that are thought to mediate the force of gravity. However, they have not yet been directly observed, and their existence is still a matter of debate.

* Virtual particles: Virtual particles are particles that are created and destroyed in pairs for very short periods of time. They are not directly observable, and their existence is inferred from their effects on other particles.

* Antiparticles: Antiparticles are particles that have the same mass as their corresponding particles, but opposite charge. For example, the antiparticle of the electron is the positron, which has the same mass as the electron, but a positive charge.

* Quarks: Quarks are the basic building blocks of protons and neutrons. They come in six different types, or "flavors," and are held together by the strong nuclear force.

Some specific examples of non-particles include:

* Waves: Waves are not particles, as they do not have a definite location or momentum. Instead, they are disturbances that propagate through space or matter.

* Fields: Fields are not particles, as they do not have a definite location or momentum. Instead, they are regions of space that have a certain value for a physical quantity, such as temperature or pressure.

* Forces: Forces are not particles, as they do not have a definite location or momentum. Instead, they are interactions between particles that cause them to move or change their state.

In general, anything that does not have a definite location and momentum is not a particle.
