The Higgs boson with mass couples to quarks and leptons to give them mass. What was the nature of these particles before they acquired mass? Were they virtual particles?
No, before that they were just fields, not particles at all.Ranku said:The Higgs boson with mass couples to quarks and leptons to give them mass. What was the nature of these particles before they acquired mass? Were they virtual particles?
Can't fields be quantized as particles, just as the Higgs field can be quantized as Higgs particles?Demystifier said:No, before that they were just fields, not particles at all.
In many situations, especially when interactions are strong, fields cannot be easily quantized as particles. More precisely, the Hamiltonian eigenstates are not states with a definite number of particles.Ranku said:Can't fields be quantized as particles, just as the Higgs field can be quantized as Higgs particles?
So then what is it that the Higgs particle is coupling with to give mass to quarks and leptons - is it the field-state of the future quarks and leptons?Demystifier said:In many situations, especially when interactions are strong, fields cannot be easily quantized as particles.

You misunderstood. We always have fields. Sometimes those fields look like particles, but they are still fields.Ranku said:So then what is it that the Higgs particle is coupling with to give mass to quarks and leptons - is it the field-state of the future quarks and leptons?

You have to be careful with this picture, as although it is a good demonstration of the effect it is essentially a classical argument. Even at the classical level it tends not to work if you push it too much.charters said:Peter, does it matter (apart from convention) whether ##Z## "eats" ##\bar H^0## or ##H^0## or an arbitrary linear combo of the two?

So how does the 'leftover' Higgs boson acquire mass by itself? Or, is it that it remains a massless field and the high energies at LHC transfer sufficient energy to it to become massive and be detectable as such?PeterDonis said:The Higgs boson ##H## is what we observe in experiments at the LHC; it is actually the "leftover" part of the Higgs field that did not get eaten.

Wanted to clarify one more thing: When the Higgs fields couple to the quark and lepton fields, does that happen after the Higgs boson that represents the Higgs fields has already acquired mass?PeterDonis said:We also have that the quark and lepton fields now are coupled to the Higgs fields in a more complicated way to give them mass.

The Higgs Boson is a subatomic particle that is believed to give mass to other particles, such as quarks and leptons, through interactions with the Higgs field.
The Higgs Boson was discovered in 2012 by scientists at the Large Hadron Collider (LHC) in Geneva, Switzerland. They used high-energy particle collisions to observe the particle and its decay products.
The discovery of the Higgs Boson confirmed the existence of the Higgs field, which is a crucial component of the Standard Model of particle physics. It also helps explain how particles acquire mass, which is a fundamental property of matter.
The Higgs Boson interacts with the Higgs field, which permeates all of space. As particles move through this field, they experience resistance, similar to how objects moving through water experience drag. This resistance is what gives particles their mass.
The discovery of the Higgs Boson has allowed scientists to further understand the fundamental building blocks of the universe and how they interact. It also opens up new avenues for research and could potentially lead to the discovery of new particles or theories beyond the Standard Model.
