Giving mass to other particles?

In summary: This process still occurs in the universe now, giving mass to particles that interact with the Higgs field. However, it does not give mass to particles that do not interact with the Higgs field, such as photons. In summary, the Higgs bosons are heavy and unstable particles that can be created in particle accelerators like the LHC. They are responsible for giving mass to other particles in the Standard Model through spontaneous symmetry breaking. The Higgs boson itself is a result of this process and does not carry any specific force, unlike other bosons. This process still occurs in the universe today, giving mass to particles that interact with the Higgs field.

TL;DR Summary
They say at the Big Bang all the particles does not have mass. It’s the Higgs Bosons give them mass...
Higgs bosons are very heavy particles (probably 1000 times heavier than a protons) and very unstable. Now we can create them in particle accelerators like LHC, like countless of other particles.
But wait. This one can give mass to particles without mass, does this violate the conservation of mass or energy? Or the laws of physics is different at the beginning of time? Also I heard a Boson particle is the one usually carries a force (like gravity, electromagnetic forces and nuclear force). If Higgs boson was a boson, what kind of force does it carry? And what makes it capable of bringing mass? Does this process still work in the universe now (like giving mass to photons)?

The laws of physics were the same back then as they are now. Strictly speaking none of the particles in the SM are massive in the traditional sense (dirac mass, quadratic scalar mass), it's only when you take the weak field limit in the Higgs doublet that you get terms that look like mass terms.

The "force" bosons originate from lorentz vector fields while the higgs comes from a lorentz scalar (technically a lorentz doublet under ##SU(2)_L##), this makes a world of difference as the higgs field doesn't implement a local gauge symmetry like the vector bosons do. In a sense I guess you could consider the higgs to be a "force" in the sense that it can mediate interactions.

Higgs field, not the boson itself.

No, that's not what "they" say.

Particles gain mass in the Standard Model via spontaneous symmetry breaking, which involves the Higgs field. The Higgs boson that was observed in the LHC is what is left over from the Higgs field after the spontaneous symmetry breaking and the gaining of mass by other particles. The observed mass of the Higgs boson is therefore separate from and not connected to the masses of the other particles.

1. How is mass given to other particles?

The mass of particles is given by the Higgs field, which is an energy field that permeates throughout the entire universe. When particles interact with this field, they acquire mass.

2. What is the role of the Higgs boson in giving mass to other particles?

The Higgs boson is a particle that is associated with the Higgs field. It is responsible for giving mass to other particles by interacting with them and transferring energy to them, thus giving them mass.

3. Are all particles given mass by the Higgs field?

No, not all particles are given mass by the Higgs field. The Higgs field only interacts with certain types of particles, such as the W and Z bosons, and the fermions (quarks and leptons).

4. Can mass be created or destroyed in this process?

No, mass cannot be created or destroyed in this process. The Higgs field only gives particles mass, it does not create or destroy it. The total mass of a closed system remains constant.

5. How does the Higgs field affect the behavior of particles?

The Higgs field affects the behavior of particles by giving them mass. This mass affects the way particles interact with each other and determines their motion and behavior in the universe.
