Questions tagged [carrier-particles]

Use for force carrier particles, quanta of characteristic quantum fields, usually gauge fields, such as the quanta of electromagnetic fields (photons), of the electroweak interactions (EW bosons), and of the strong interactions (gluons); elastic forces on on a lattice (phonons); nuclear forces (pions); gravity forces (gravitons), etc. May include conjectural particles from GUTS (like their proton-decay-inducing gauge bosons).

If gravity turns out to be mediated by exchange particles, would that imply a problem with gravitational fields around a black hole?

In general relativity, gravity is a distortion of spacetime due to mass. Its effects travel (if that's the right word) at the speed of light. In the SM all 3 other known interactions are mediated by ...

Models of confinement based on negative mass carriers

In the old Yukawa model of nuclear forces, it was proposed that short-range interactions were mediated by exchanges using massive force carriers (originally, mesons were proposed for this). If one ...

What does it mean for a graviton to have mass?

On wikipedia we can read: Astronomical observations of the kinematics of galaxies, especially the galaxy rotation problem and modified Newtonian dynamics, might point toward gravitons having non-...

Why is the $W$ boson (and none other elementary boson) the only with EM charge?

I have read this question: Working out the charge of a W Boson The role of W bosons in the weak nuclear force and beta decay The W, Z, together with the photon comprise the four gauge bosons of ...

Gravitons from linearized gravity

Linearizing gravity as follows: $$ g_{\mu\nu}=\eta_{\mu\nu}+h_{\mu\nu} $$ Up to this point, everything is a 4x4 matrice. How does one eventually recover a spin-2 particle which, according to https:/...

Probability of breaking a covalent bond through collisions

I was watching a lecture and at some point they say that for a covalent bond of 1.1 eV and for particles with 0.026 eV mean energy, the number of particles requiered to break the bond is 42, that is 1....

Possibility of the existence of Graviphotons?

I have been attempting to do research on the graviphoton yet I can find almost nothing, and many of the articles I do find are locked behind hefty paywalls. It is an interesting possibility to think ...

Layperson can not get his head around Force Carriers

I read all I can but, this is vexing me. It realtes to Quantum-Mechanics, and I believe Quantum Field Theory, and maybe even Quantum Chromodynamics. Before the Higgs the Model was 16 instead of 17 we ...

Gravitons, photons and conservation of momentum

How can gravitons be emitted from a mass to cause an attractive force to another mass? The same question could be asked of attractive e-m forces as well. Don't these violate the conservation of ...
