Why is it that the boson for the electromagnetic force does not have a charge? I apologize if this question is rudimentary, as all of you guys are WAY out of my league. Thanks!

bhobba said:Well it is the carrier of the electric charge so it 'sort of' seems reasonable it doesn't have a charge.
Drakkith said:Bhobba, are you aware that the force carrier of the color force, the gluon, carries color charge?

ChrisVer said:How does U(1) say it must be chargeless?
ChrisVer said:In fact under global U(1) nothing is charged because everything transforms trivially (even the fermionic field equations -dirac equation).
*editted since I read you wrote "global"*
Local gauge invariance (of any group not only Abelians) rquires the force carriers to be massless vector fields.Matterwave said:[STRIKE]... the fact that the gauge group of E&M is U(1), an Abelian group, would only require the force carriers to be mass less.[/STRIKE]
Now this follows from the Abelian nature of the gauge group.That the force carriers are charge less is reflected in the fact that the equations of motion of the field (the Maxwell equations) are linear.
Non-lineariry of the EOM and the charged nature of the force carries both follow from the non-abelian nature of the gauge group.A charged force carrier would lead to non-linear field equations.

Matterwave said:And indeed that is why I redacted my comment. But it is interesting that after spontaneous symmetry breaking the photon turns out to be the mass less one while the W and Z bosons are the massive ones. I have to look closer at the derivations, but have not had time to yet.

atyy said:http://arxiv.org/abs/0809.1003 (Eq 27-29, and Eq 30) seems to argue that the photon can be massive without spoiling gauge invariance.

The charge-less boson of the electromagnetic force is a hypothetical particle that is predicted to exist by some theories in physics. It is thought to be responsible for mediating the electromagnetic force, which is one of the four fundamental forces in nature.
The charge-less boson of the electromagnetic force is different from the Higgs boson in several ways. The Higgs boson is responsible for giving particles their mass, while the charge-less boson is thought to be responsible for mediating the electromagnetic force. Additionally, the Higgs boson has been observed and confirmed by experiments, while the charge-less boson is still a theoretical concept.
Studying the charge-less boson can help us better understand the fundamental forces and particles that make up our universe. It can also provide insights into the unification of forces and the search for a theory of everything. Furthermore, if the charge-less boson is found to exist, it could have practical applications in technology and energy production.
Scientists are using high-energy particle accelerators, such as the Large Hadron Collider, to try and create the charge-less boson in controlled experiments. They are also looking for indirect evidence of its existence through the analysis of data from these experiments.
If the charge-less boson is discovered, it would have significant implications for our understanding of the universe. It could help bridge the gap between quantum mechanics and the theory of relativity and could potentially lead to new technologies and advancements in our understanding of the fundamental forces of nature.
