The Higgs boson and the graviton are both theoretical particles, but they have distinct properties and roles in physics, and they are not considered different forms of the same thing.
The Higgs boson is a particle that was discovered experimentally at the Large Hadron Collider (LHC) in 2012. It is associated with the Higgs field, which is a quantum field pervading space. The Higgs field is hypothesized to interact with certain particles, giving them mass. The Higgs boson is the quantum excitation of the Higgs field and is primarily involved in the mechanism of mass generation in the Standard Model of particle physics.
On the other hand, the graviton is a hypothetical elementary particle that is predicted in some theories of quantum gravity, such as string theory. It is thought to be the carrier particle of the gravitational force, similar to how photons are the carrier particles of the electromagnetic force. The graviton, if it exists, would be associated with the gravitational field and would mediate the interactions between masses.
While both the Higgs boson and the graviton are particles, they have different properties and play distinct roles in physics. The Higgs boson is related to the mechanism of mass generation, while the graviton, if it exists, is associated with the gravitational force. They are not considered different forms of the same thing, but rather separate entities with different characteristics and implications in their respective areas of physics.
