A Fermion interacts with the Higgs field

Click For Summary
SUMMARY

The discussion centers on the interaction of fermions, specifically the top quark and electron, with the Higgs field as described by Matt Strassler. The top quark converts between left-handed and right-handed states approximately 100 trillion trillion times per second due to the Higgs field's influence. In contrast, the electron, being significantly lighter, undergoes this conversion roughly 300,000 times slower, at about 3E20 times per second. The conversation also clarifies that fundamental fermions do not scatter off the Higgs field itself but may interact with Higgs particles, which affects their mass rather than their momentum directly.

In a blog post of Matt Strassler we are told about the top quark,

"when the Higgs field is not zero, its presence, and the fact that it has a direct interaction with the top-left and the top-right, forces the top-left to convert over to a top-right, and back again. How often does this happen? About a 100 trillion trillion (100,000,000,000,000,000,000,000,000) times a second. "

From, https://profmattstrassler.com/artic...known-particles-if-the-higgs-field-were-zero/

Because an electron is roughly 300,000 lighter than the top quark will the electron convert from electron-right to electron-left roughly 300,000 times slower, only about 3E20 times a second?

Edit, should have read further, the answer to the above is yes, sorry.

If the fundamental fermions are massless and constantly scattering off the Higgs field is there a relationship between their average momentum and their rest mass?

A fermion scatters off the Higgs field into a new direction, are all directions equally likely?

Thanks!

Unless I misread the article, they aren't scattering off of the higgs field. They might scatter off of a higgs particle, but not the field itself. So the field has no effect on their momentum in the way that a collision might (though it might in other ways, such as by influencing their mass).
 
Don't take analogies too literally. And I think even the analogy is poor here.
