Is the current thinking in String Theory that the vibrating strings (quarks) are picking up their mass from the Higgs Field? ....

...whereas a photon must NOT be a vibrating string..since it "skates" through the proposed Higgs Field?

Stonecut. Could be, I'm not sure, but the latest thinking from Wilczek is that the great majority of the mass of a nucleon comes from the gluons that hold the quarks together in chromodynamics, not the quarks themselves.

This (http://www.scientificamerican.com/article.cfm?id=how-does-the-higgs-boson#comments) article from Scientific American has a nice summation. There is this quote though about string theory:

"It makes no explicit or testable predictions or explanations, and it has no direct connections to Higgs bosons. Before such connections can happen, we will have to learn how our actual world can emerge from the higher dimensional theory and how the strong, weak and electromagnetic forces, and the quarks and leptons, emerge from string theory."

Interestingly, if a Higgs is found and has a mass of 90 to 140 proton masses, it will be a big plus for string theory as that is the mass predicted for a Higgs in superstring theory.

Thank you for the responses and links. Its a great time to be alive! LHC is firing up at the end of February...

I thought that string theorists propose that mass is a byproduct of the tension and vibration patterns of Planck-sized strings.
