Nov 29, 2021 · What is a graviton? Similarly how a photon is a particle you get after quantizing free electromagnetism, a gluon is a particle you get after quantizing linearized Yang-Mills; you …

Jan 18, 2022 · In the analogy between photons and gravitons, (real) photons make up electromagnetic waves such as light and radio waves; and (real) gravitons make up …

A graviton is a theorised particle (specifically a boson). It is said to be its own antiparticle. It has a special role in general relativity (being that the science is all about gravitation and the warping …

Perhaps we still need to have a (spin 2) graviton, but if we do, even its quantum spin must be relative to the only invariant spin state, which is the zero spin state of Higgs. Otherwise, there …

Feb 25, 2021 · Usually there are a huge number of indices (6 for a 3 graviton vertex) with lots of integrations by parts to keep track of. Nevertheless, it should always be clear how to derive the …

Dec 23, 2018 · 2) A graviton is necessary since we believe graviton excitations, maybe Wheeler's space-time foam in some form or alike, must dominate the description of very dense objects …

May 2, 2015 · You are basically asking how forces work in quantum field theory, because the graviton is the force carrier in a QFT description of gravity. Have a read through this article by …

Jul 18, 2019 · What is the graviton propagator? What is the off-shell 3 point function for the GR vertex? DeWitt has a collection of papers that contain this but the expression for the vertex is …

Aug 12, 2016 · A graviton is postulated to be chargeless particle state. Moreover, it doesn't have any other quantum numbers (aside from spin) that would need to be conserved. Therefore, a …

Feb 23, 2021 · The main difference is that gravity is always attractive while electromagnetic force is not. A photon intermediating electromagnetic force has spin 1 while graviton should have …
