Theoretical physicist from Vienna, Austria. My focus is the theory of strong interactions and its study via the AdS/CFT correspondence, but I am also interested in aspects of general relativity, particle physics and string theory not related to holography.

comment Closed strings = open ones attached to a D0-brane?
@JustAsking: The potentials will not cancel everywhere. The system would be similar to a dipole in electrostatics, which has non-vanishing potential and field-strength.

@wolprhamjonny: The answer is not theory-dependent. That protons are made of quarks and gluons and are subject to beta decay is both an experimental fact and theoretically understood. String theory does not change this.

How does this answer the question? What you write simply concerns a different interpretation of elementary particles, but not the relation between a particle's decay products and constituents.

@GianniTee: The point is that decay in particle physics is not equivalent to "breaking apart into constituents", but it could more accurately be imagined as a conversion. Probabilities are in general not symmetric under reversal: their calculation is a very non-trivial task, often with unforeseeable outcome.
