Before measurements, quantum states are vectors in Hilbert space and there may not even be momentum or position chosen before wave function collapse or measurement. I'd like to understand how mass or the higgs field couple to wave function. Can higgs home in to the specific ray or vector in Hilbert space or does the higgs field only couple to it after collapse of the wave function (or measurement). If it is prior, then higgs has capability to navigate the vectors in Hilbert space and find the specific basis? (perhaps explaining why there is mass in the atoms even without being measured?) I understand that in gauge theory, masses can't be forced directly into the equations of the equation or the symmetry is destroyed. So higgs field were proposed to give masses to the properties, but how they exactly interact in Hilbert configuration space.
