Why are interactions always mediated via bosons (as opposed to fermions)? [duplicate]

Weak, Strong and electromagnetic force are mediated via bosons. I've come across the Walecka-model where the exchange particles are $\sigma$ and $\omega$ mesons; bosons again. why are interactions ...

Why do forces have to be mediated by bosons? (Or do they?) [duplicate]

In another question, I was asking about the interaction between photons and electrons. It was suggested that in compton scattering there is no particle to "mediate" the force. The tree-level diagrams ...

Why bosons have integer spin and fermions have half-integer ones?

Due the fact that the fermions are the "block particles" and the bosons are the "carriers" I just came out with the question that, why the "block particle" have half-integer spin and the "carriers" ...

Is there some special case where a fermion can mediate a force?

Looking at the comments of this questions Does the gravitino contribute to the gravitational interaction? and even considering that the answers here in this other question Why are all force particles ...

Why don't we call the fermions in the standard model force carriers?

Maybe this is a chicken-and-egg problem, but couldn't we call all the bosons fundamental and treat the fermions as force carriers between them? EDIT: After all we never see the asymptotic states of ...

Why are photons bosonic?

I am studying the quantization of the electromagnetic field. My text quantizes by changing amplitudes to ladder operators, by putting in an action and by imposing bosonic commutation relations upon ...

Can elementary particles be nicely classified into "force transmitters" and "force emitters"?

This well-received answer begins with First of all, you can't compare photons with electrons. They are different types of particles (spin 1 vs spin1/2; force transmitter vs force emitter). I'd ...

Is there a difference between boson and bosonic?

I read about Bose-Einstein condensate consist of bosonic atoms at incredible low temperature do not obey Pauli exclusion, I am wondering what happens if it is possible to create fermionic photon for ...

Are interactions mediated by spin 3 or higher bosons allowed in mainstream QFT? [duplicate]

Electromagnetism, the strong interaction, and the weak interaction are mediated by spin 1 particles, and in Quantum Gravity spin 2. I saw in this question that the answers pointed out how ...
