What is the difference between string that make phontons and proton?

Click For Summary
SUMMARY

The discussion centers on the differences between strings that constitute photons and protons as per string theory. Photons are massless particles, while protons possess mass due to their composition of quarks and gluons. The mass of protons arises from their interaction with the Higgs field, suggesting that all particles, except the Higgs boson, are intrinsically massless. The vibrational states of the strings determine the properties of these particles, including mass.

PREREQUISITES
  • Understanding of string theory principles

according to the string theory, what is the difference between the strings that make the photons and the strings that make the protons? photons don't have mass and protons do, does it all ultimately rely on simply how the strings vibrate, or what? do photons' strings have lowest energy possible, or they have very few strings, so that's why they are massless??

Protons are not elementary particles, they consist of quarks (with mass) and gluons (massless). In the Standard Model, this mass comes from the interaction with the Higgs field, the particles itself are introduced as massless. String theory should reproduce that, so no particles (apart from the Higgs boson) have an intrinsic mass, that just emerges from the interactions.
