New Method Sheds Light on Hyperon Interactions in Neutron Stars - Garryerkont - 06-07-2025
A research team led by Professor Yong Gaochan from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences has introduced a novel experimental approach to probe hyperon potential, offering a promising path toward resolving the longstanding "hyperon puzzle" in neutron stars. The findings have been published in Physics Letters B and Physical Review C.
In the dense interiors of neutron stars, conventional theory predicts the formation of hyperons—particles containing strange quarks, such as Λ hyperons. These particles are known to soften the equation of state (EoS), limiting the mass that neutron stars can support. However, astronomical observations have confirmed the existence of neutron stars with masses close to or exceeding twice that of the Sun, contradicting these theoretical constraints.
The hyperon potential, which describes the interaction between hyperons and nucleons, is considered a key factor in addressing this discrepancy. If the hyperon potential becomes increasingly repulsive at high densities, it could counteract the EoS softening, thereby allowing more massive neutron stars to exist.
"Heavy-ion collisions offer a promising method for investigating high-density hyperon potentials," explained Prof. Yong. "But in traditional setups, hyperons are typically produced as secondary particles, making their behavior difficult to isolate due to interference from various sources."
To overcome this limitation, the team proposed a new type of experiment. Their method uses Λ-hypernuclei—atomic nuclei that contain Λ hyperons—as projectiles to strike normal nuclear targets at 400 MeV, an energy below the threshold for producing new Λ hyperons. This ensures that any Λ particles detected must originate from the original projectile, eliminating the confusion caused by in-collision production.

By analyzing the elliptic flow patterns of Λ hyperons after impact, the researchers found that flow behavior at different rapidities provides valuable information. Negative rapidity regions are especially sensitive to high-density hyperon potentials, while positive rapidities reflect low-density interactions. This dual sensitivity enables the extraction of hyperon potential characteristics across a wide density range.
The team also explored the formation of light hypernuclei, such as hypertritons, using simulations of carbon–carbon collisions. Their results show that while overall hyperon production is governed by the nuclear EoS, the formation of light hypernuclei is more directly affected by the hyperon potential—at both high and low densities—depending on the beam energy used (1.1 GeV vs. 1.9 GeV).
These insights provide a practical experimental framework for further investigation into hyperon interactions and the structure of neutron stars. "We hope these proposed experiments can be realized at major research facilities," said Prof. Yong. "Such work could deepen our understanding of strong interactions between strange and ordinary matter and bring us closer to resolving the hyperon puzzle."
