TL;DR
A question on whether a particle's intrinsic identity requires a continuous physical cost to maintain, and whether this idea has been explored in the literature.
My question is: Does maintaining a particle's intrinsic identity require a continuous, irreducible physical cost?

I have been thinking about this for a long time and would like to hear the community's thoughts.

All physical theories treat a particle's intrinsic identity (mass, charge, spin) as a static initial condition. An electron is an electron, and no ongoing process is required to maintain this. The fact that a particle stays itself is taken as a free, unproblematic given.

What if this assumption is wrong? If maintaining a particle's identity requires a physical cost, then being an electron is not a static given but a dynamically maintained state.

If this idea has merit, it should produce observable predictions that differ from standard theory:

1. An absolutely isolated system, shielded from all known environmental noise, should exhibit statistically significant, irreversible drift in its conserved quantities (mass, charge, magnetic moment) over sufficiently long timescales. This drift would be random in direction, extremely small in magnitude, but non-zero.
2. If a superposition state requires more maintenance than a single eigenstate, superpositions might show a systematically shorter coherence lifetime than expected from standard decoherence theory alone.
3. Different particles may have different maintenance costs, perhaps offering an alternative perspective on proton decay or dark energy.

My question to the community: Has this specific idea, that maintaining a particle's identity is a physically costly process rather than just a logical given, ever been formally proposed or discussed in the literature? If so, where? And what existing experimental data or observational constraints already rule this out, or place upper bounds on such an effect?

I am not proposing a new theory. I am asking whether this specific conceptual possibility has been explored, and if not, whether it deserves to be.

You are unambiguously proposing a new theory. We do not evaluate new theories.

However, in addition to this being a new theory, your premise is incorrect:

This is simply not true. Many particles decay. In doing so they cease being themselves and become something else. For the particles that are stable, it is not a given but a derived fact for that specific particle.
