The strong nuclear force that illuminates structure of a neutron star’s core, The most common material is held together by an invisible subatomic adhesive known as the strong nuclear force, one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak force.
The strong nuclear force is responsible for pushing and pulling between protons and neutrons in the nucleus, which prevents the atom from collapsing.
In the nucleus, most protons and neutrons are far enough apart so that physicists can accurately predict their interactions. This prediction is debated, when subatomic particles are so close that they practically overlap. The strong nuclear force that illuminates structure of a neutron star’s core.
While such short-range interactions rarely occur in most of Earth’s material, they determine the nucleus of neutron stars and other highly dense astrophysical objects.
When scientists began to study nuclear physics, they struggled to explain how strongly nuclear power played at such short distances.
In previous experiments with particle accelerators, they conducted extensive data analysis and found that a surprising transition in their interactions occurred when the distance between protons and neutrons became shorter.
If the strong nuclear force primarily pulls protons into neutrons at great distances, the forces basically become indiscriminately at very short distances: interactions can occur not only to attract protons to neutrons, but also to repel or push neutron pairs individually .
The interaction of ultra-short distances between protons and neutrons is rare in most atomic nuclei. To recognize this, atoms must be pumped with large numbers of very high-energy electrons, some of which may meet a pair of nuclei (protons or neutrons) that move with large pulses, which indicate that the particle is in extreme conditions. need to interact short distances.

Using this general approach, the team examined quadrillion electron collisions and succeeded in isolating and counting pulses from several hundred high-pulse pairs.
Researchers compared these pairs with “neutron star droplets” because their momentum and the distance between them are similar to the very dense conditions in the neutron star’s core.
They treated each isolated pair as a “portrait” and organized several hundred shots during the distribution of the pulse. At the lower end of this distribution, they observe the suppression of proton-proton pairs, which shows that the strong nuclear force functions mainly to attract protons at intermediate impulses and short distances to neutrons.

During distribution, they observe the transition: there appear to be more protons and protons because of the symmetry of the neutron-neutron pair, which implies that with larger pulses or at shorter distances, the strong nuclear force does not only affect protons. and neutrons, but also protons and protons and neutrons and neutrons.
This coupling force is understood to be repulsive, which means that neutrons interact with each other over short distances and repel each other.
The team made two more discoveries. On the one hand, their observations agree with the predictions of a surprising simple model that illustrates the formation of short-term correlations due to strong nuclear energy.
On the other hand, contrary to expectations, neutron star nuclei can be described strictly by interactions between protons and neutrons, without having to explicitly take into account the more complex interactions between quarks and gluons, which make up individual nucleons.

When the researchers compared their observations with several existing strong nuclear power models, they found an extraordinary agreement with the predictions of Argonne V18, a model developed by the research team.
This means that if scientists want to calculate the properties of neutron stars, they can use this special Argonne V18 model to accurately assess the interaction of strong nuclear forces between pairs of nucleons in the nucleus.
People think the system is so dense that it should be considered a quark and gluon soup, researchers explained.
But even at the highest densities, we can illustrate this interaction with the help of protons and neutrons; They seemed to be guarding their identity and did not turn into this quark bag. The core of neutron stars could be simpler than expected. This is a big surprise.
