Electrostatic in string theory or LQG

Click For Summary
SUMMARY

The discussion centers on the mechanisms of electrostatic repulsion between electrons as explained in String Theory and Loop Quantum Gravity (LQG). It establishes that interactions between standard model particles are fundamentally similar in both frameworks, with String Theory providing a more detailed description of particles and fields. Specifically, electrostatic repulsion is described in Quantum Electrodynamics (QED) through quantum fields and virtual particles, while in String Theory, these interactions correspond to specific string states. The reference to "QED and string theory" highlights the realization of QED through open strings between D9-branes and a D3-brane.

How the repulsion between electrons occurs in String theory and in the loop quantum gravity? The electrons will also create electrostatic fields, or will it be the another mechanism?

Moderator's note: Moved to Beyond the Standard Model forum as that is where discussion of String Theory and Loop Quantum Gravity belongs.
 
All interactions between standard model particles are essentially the same in string theory. It's just that you can say more in string theory about what the particles and fields are.

For example, electrostatic repulsion will have a description in QED, in terms of quantum fields and virtual particles. The explanation in string theory should be identical up to a certain point, but the "virtual photons", etc, would actually be particular string states.

For reference I mention "QED and string theory", which aims to realize just QED, via open strings stretched between space-filling D9-branes and a four-dimensional "probe" D3-brane. The real world contains many other forces and particles, and so the string models are accordingly more intricate.
