164 2 As I understand it (e.g. from discussions around the Fermi field theory of the nuclear force), a spin 1/2 particle can emit a spin-1 particle and simultaneously flip its spin (say, spin +1/2 -> photon +1 & spin -1/2); but how does this work with spin-2 particles? Does it need to emit pairs in opposite directions (so no spin flip)?.

The photon is a boson with spin 1, which is a typical boson spin. Exceptions are the graviton with spin 2 and the Higgs boson with spin 0. The spin classification of particles determines the nature of the energy distribution in a collection of the particles. Particles of integer spin obey Bose-Einstein statistics, whereas those of half-integer.

Additionally, it can be shown that any massless spin-2 field would give rise to a force indistinguishable from gravitation, because a massless spin-2 field would couple to the stress–energy tensor in the same way that gravitational interactions do. This result suggests that, if a massless spin-2 particle is discovered, it must be the graviton.

Thus if we find a spin-2 massless particle, we'll know it's a graviton. This spin-2 behavior also explains the fact that conventional gravity only attracts, unlike electromagnetism, which both attracts and repels. Particles can be either bosons, which have an integral value of spin (the quantum mechanical equivalent of angular momentum due to rotation of the particle) that is a whole number value such as.

Interacting massless spin 2 particles! to describe spin 2 gravitons. Much easier way the diffeomorphisms are realized -the corresponding eld components can be projected out from the outset. At least one spin-0 particle, called the Higgs boson, is postulated to explain the origin. The weak and strong interactions are also associated with the exchange of spin-1 particles.
What does it mean for a particle to have a spin of 2? - Quora.
Weinberg gives an argument in his QFT book which addresses this question, but with one added assumption: the spin-2 particle leads to a long-range interaction. The traditional route is to start with a field and see what particle states you can build. Weinberg goes in the opposite direction.

The massless, spin 2 particle was the hypothesized graviton: an undetected particle which mediates the force of gravity Ver simply put, dualities are symmetric connections between two string theories..

2 Answers. There are two quantum numbers to consider, the total spin = 1/2 and the azimuthal or projection quantum number on an axis, say z with angular momentum +-hbar/2. This quantum number is also 1/2 for electrons. (The x and y components are undefined by the uncertainty principle as spin quantum number and spin z component are defined. What spin does a graviton have? While the matter particles of the Standard Model are spin 1/2 and the Standard Model force-carrying particles have a spin of 1, gravitons must have a spin of 2. (This proceeds from the fact that gravity stems from the distribution of energy and momentum in the universe. What is a spin-2 particle?.

So for Spin -2, the particles can be 2,1,0,-1,-2. There is a lot more to spin than this, but we can always get into that more if you'd like. tl;dr: A spin-2 field is a theory about particles that can have spin states of 2,1,0,-1,-2. Thanks for the clear response, you should be up there with rrc. 12 A particle has an intrinsic spin angular momentum Spin ½ particles: Electrons, protons, neutrons and neutrinos all have an intrinsic spin characterised by the quantum number s = 1/2 Particles with..

Scientists have achieved the ultimate speed limit of the control of spins in a solid state magnetic As an elementary particle, the electron cannot be broken down into smaller particles, at least as far as. This means that the particles are indistinguishable. Both particles are labelled A. Recall that bosons have integer spin: 0, 1, 2, etc. For Bose statistics any number of particles can be in one state.
