Why is the Higgs field a scalar field? I understand if it is one, it will have no spin and no angular momentum. But understanding that a particle is a scalar seems to me a leap of faith. What am I not getting?
Naty1 said:The Higgs field arises out of the spontaneous symmetry breaking during inflation.
BenTheMan said:all of the symmetries that the higgs was charged under are no longer symmetries. This means that the higgs (which does the symmetry breaking) must be charged under the electroweak symmetry, but it can't break the SO(3,1) symmetry of GR. The only type of particle that does this is a scalar particle. More succinctly, it is CALLED a scalar particle because it doesn't have any transformation properties under the SO(3,1) of gravity. :)
Am I understanding this right that the charged-ness, the turned on position, of the Higgs field is a consequence of the symmetry? Or is it the breaking?
When I hear talks about scalar fields, I envision something like a sea of speeds without any objects being sped along.

Nothing wrong with scalar particles, pions and all other mesons are scalar particles. For non-mathematical dscription of hidden symmetries see

A scalar field is a type of field in physics that assigns a scalar value (a single number) to every point in space. This value can represent a physical quantity, such as temperature or pressure, or a mathematical quantity, such as a potential energy or a probability density.
The Higgs field is considered a scalar field because it assigns a single number, known as a Higgs field value, to every point in space. This value determines the strength of the Higgs field at that point, which in turn gives mass to particles that interact with it.
The Higgs field interacts with particles that have mass, such as quarks and electrons, and gives them mass through a process known as the Higgs mechanism. This mechanism involves the particles interacting with the Higgs field, which causes them to gain mass and become more difficult to accelerate.
No, the Higgs field is not considered a fundamental force. It is a type of field, similar to the electromagnetic field, that interacts with particles to give them mass. The four fundamental forces in physics are gravity, electromagnetism, the strong nuclear force, and the weak nuclear force.
The Higgs field is important in understanding the origin of mass in the universe and how particles interact with one another. It also plays a crucial role in the Standard Model of particle physics, which describes the fundamental particles and their interactions. By studying the Higgs field, scientists hope to gain a deeper understanding of the fundamental nature of our universe.
