No, but I can write down a formula containing a new particle, with the particle's properties (for the case of an electron, not u-quark).
Doesn't, for example, a left-handed electron change into a right-handed one by coupling to the Higgs field? Which is why the neutrino has no Higgs-induced mass?topsquark said:Hint: Look at the Higgs sector.

You need a bar above one of them to preserve gauge symmetries...talanum52 said:It's uR and uL.
I thought the same. Loosely speaking, before the SU(2)LxU(1)Y symmetry is broken, Higgs couples the ##\phi _l## and ##\bar{\phi} _r##: ##\bar{\phi} _l h {\phi} _r##. When the symmetry is broken this becomes ##m\bar{\phi} \phi##, where the ##\phi##'s are superpositions of l and r.malawi_glenn said:You need a bar above one of them to preserve gauge symmetries...
Yes, according to the Standard Model of particle physics, left handed up quarks can transform into right handed ones through a process called weak interaction.
This transformation occurs because of the weak force, one of the four fundamental forces of nature. The weak force allows for particles to change their "handedness" or chirality, which is a property that determines how they interact with other particles.
Yes, this transformation is a common occurrence in particle interactions. In fact, it is necessary for the formation of certain particles, such as protons and neutrons.
Yes, there are other theoretical processes, such as the Higgs mechanism, that could potentially cause this transformation. However, these processes have not yet been observed or confirmed.
The transformation of left handed up quarks into right handed ones has important implications for our understanding of the Standard Model and the behavior of particles. It also plays a crucial role in the formation of matter in the universe.
