If gravitons exist, it should be possible to create them at the LHC, but they would rapidly disappear into extra dimensions. Collisions in particle accelerators always create balanced events – just like fireworks – with particles flying out in all directions.

Can gravitons be generated?

Also according to Particle Radiation and Contact Interaction Theory, any traveling particle with the capability of making contact interaction with the same particles in space will form a field such as graviton and electron.

Will the graviton ever be discovered?

One consequence of that: while scientists know of particles associated with the strong, weak and electromagnetic forces, they have yet to discover a particle of gravity, or graviton. ... “The most important result is the possibility of verifying the quantum nature of the gravitational field,” said Sawyer.
