Have there been any measurements of the strong force? Also its curve of the strength of the force vs distance

Discussion Overview
The discussion revolves around the measurement of the strong force, specifically its strength as a function of distance. Participants explore the complexities involved in representing this relationship, including the influence of particle orientation and the distinction between different aspects of the strong force.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about measurements of the strong force and its strength versus distance curve.
- Another participant suggests that while a curve can be created, it may not be very useful due to the dependence of the strong force on particle orientation (spin), indicating the need for a family of curves instead of a single representation.
- The distinction between the strong force binding quarks in hadrons and the higher-order residuals of the strong force, which bind nucleons in atomic nuclei, is emphasized.
- A participant mentions challenges in simulating the strong force, noting that calculations tend to diverge at larger distances.
- Quasi-classical solutions based on matter waves made of pi-mesons suggest a long-range tail of the strong force that can extend up to 20000 fm before decaying exponentially.
- It is noted that in reality, the strong force is effectively shielded by a "shell" of virtual mesons, confining it to a range of 1-2 fm, with ongoing debate about the details of this shielding mechanism.
- Within the shield, the strong force is said to fall off with distance slower than r-2.
- A separate participant asks about an equivalent charge value to the elementary charge, which appears unrelated to the main topic of the strong force.
Areas of Agreement / Disagreement
Participants express differing views on the representation of the strong force and its measurements, with no consensus reached on the best approach or the implications of the findings discussed.
Contextual Notes
Limitations include the dependence on particle orientation and the unresolved nature of the shielding mechanisms affecting the strong force at different distances.

It is possible to create such curve, but it will not be very useful, because the strong force also depends on particles orientation (spin), therefore you need to draw family of curves rather than single curve.
Also, you should distinguish between strong force itself (which binds quarks in hadrons), and the higher-order residuals of strong force (comparable to gravitational tidal forces - this part binding nucleons in atomic nuclei).
The force(distance) curve for strong force higher order residuals is below:
Actually, we have problems simulating strong force because calculations tends to easily diverge at larger distances. The quazi-classical solutions (based on matter wave made of pi-mesons) seems to suggest long-range tail of strong force can be as long as 20000 fm before exponentially decaying. In real world, hadrons strong force is very effectively shielded by their "shell" of virtual mesons, confining strong force to just 1-2 fm range. Details on how shielding works is still a subject of scientific debate, but within shield the strong force falls with distance slower than r-2

Is there an equivalent charge value to elementary charge?
