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

- Force Strength Strong force
In summary, there have been attempts to measure the strength of the strong force at different distances, but it is difficult to accurately represent due to its dependence on particle orientation. Additionally, there is a distinction between the strong force itself and its higher-order residuals, which contribute to the binding of atomic nuclei. There is a difficulty in simulating the strong force at larger distances, as calculations tend to diverge. However, the use of matter waves made of pi-mesons suggests a long-range tail for the strong force, which is effectively shielded by virtual mesons in the real world. This shielding mechanism is still a subject of debate, but within this shield, the strong force decreases with distance at a slower rate than r-2. Some

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?
What is the strong force?
The strong force is one of the four fundamental forces of nature, along with gravity, electromagnetism, and the weak force. It is responsible for holding together the nucleus of an atom by binding protons and neutrons together.
How is the strength of the strong force measured?
The strength of the strong force is measured using a unit called the strong coupling constant, represented by the symbol αs. It is a dimensionless number that describes the strength of the force between two quarks at a certain distance.
What is the relationship between strength and distance in the strong force?
The strength of the strong force decreases as the distance between two particles increases. This relationship is described by the principle of asymptotic freedom, which states that at very small distances, the force is strong and at large distances, the force becomes weak.
How is the strong force different from the other fundamental forces?
The strong force is different from the other fundamental forces because it only acts on particles with the property of color charge, such as quarks. It is also the strongest force among the four fundamental forces, but it has a very short range compared to the other forces.
Why is it important to measure the strong force?
Measuring the strong force is important because it helps us understand the structure of matter at a fundamental level. It also plays a crucial role in nuclear physics and the behavior of particles in the universe. Additionally, studying the strong force can lead to advancements in technology, such as nuclear energy and medical imaging techniques.
