What is the difference between graviton and higgs boson

It's a pretty outlandish theory, but it's one that can actually be tested by studying the Cosmic Microwave Background. By studying the CMB closely, scientists can discover clues about what happened in the early years of the universe and possibly determine whether this new theory about gravity is right. Unfortunately, we will need to wait a few years for the next generation of telescopes—like the James Webb Space Telescope —to be launched before we find the answer.

But until then, we can only wait and enjoy the very weak gravity that we've got. Source: New Scientist. Type keyword s to search. Today's Top Stories.

Something is seriously wrong with gravity, and nobody's quite sure why. This content is imported from YouTube. You may be able to find the same content in another format, or you may be able to find more information, at their web site. Even so, the spark has ignited a fuse. Barely a week after the ATLAS and CMS bumps were made public, theorists had posted more than possible explanations to the arXiv server, a repository where physicists post data before formal publication, and the number has been skyrocketing ever since.

Yasunori Nomura of the University of California, Berkeley, was one of the first. There are some things we can already say about the putative particle. It has no electrical charge, for a start, and its spin — a quantum mechanical property — is constrained. The mathematics of spin mean that any particle that decays into two photons, which have a spin of 1, cannot itself have a spin of 1. It must also have whole-number spin. So the particle might have a spin of 2, exciting the idea among some theorists that it is a type of graviton — a hypothetical spin-2 particle that transmits gravity.

That would be the first herald of a long-awaited theory beyond the standard model that unifies gravity with the other known forces of nature. Or the particle might have spin 0, as does the Higgs — in fact, another theory is that the apparition is a heavier cousin of the Higgs.

Instead, Nomura thinks, it must be a composite particle similar to the protons and neutrons within the atomic nucleus. These are made up of quarks bound together by the strong nuclear force. The mystery particle, on the other hand, would be the first in a family bound by an entirely new fifth force that only kicks in at high energies. That might sound far-fetched, but it would just be history repeating itself. In the s and s, the discovery of a barrage of particles that turned out to be made up of quarks led physicists to the idea of the strong force.

Nomura says that, together with his postdoctoral researcher, he threw several tests at the idea — and it passed every one. Other theorists say the same about their pet theories, and Ellis urges caution — given our level of ignorance, he says, the particle could still be either elementary or composite.

The spin of the particle is wide open too. Strangely, the only thing we probably can rule out is that the particle is what many theorists, including Ellis, would like it to be: a supersymmetric particle. Supersymmetry is a theory that plugs many holes in the standard model by conjuring up a raft of heavier particles that partner each known particle.

A further oddity is that a particle so massive should decay into two photons only indirectly, via particles of at least half its mass — but there is no sign of these. The fact that there is no off-the-shelf model such as supersymmetry that supplies a particle with the right properties makes things all the more intriguing for Giudice.

They might not be the only source of surprises. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. The Higgs boson gives particles mass.

And the graviton is the theoretical force-carrier of gravity. Gravity depends on mass. So if the Higgs Boson gives things mass, it therefore gives them gravity. Is the Higgs Boson the same thing as a Graviton?

Or is there a difference? The only thing I know is that the Higgs Field is something very different from the Gravitational Field. Yet, I'm not satisfied with that fact. I want to know why the Higgs Boson is not the Graviton. The source of the gravitational field is an object called the stress-energy tensor. Even massless particles like photons generate a gravitational field. The Higgs boson, as discovered at the LHC, is a low energy effect of the Higgs field, and it's the Higgs field that is responsible for the mass of the elementary particles.
