Interested in the behavior of hadrons in nuclear matter? This research explores the role of effective hadron masses and couplings in nuclear matter using a generalized effective Lagrangian for the σ-ω model. A relationship among effective masses, couplings, and incompressibility (K) is derived. Using this relation, the study reveals that the effective repulsive and attractive forces nearly cancel each other at normal density. Conversely, if such cancellation is almost complete, the incompressibility K is found to be between 250 and 350 MeV. These findings provide valuable insights for nuclear physicists, shedding light on the dynamics of nuclear matter and the interplay of forces within the nucleus.
Published in the International Journal of Modern Physics E, this paper aligns with the journal's focus on nuclear physics, particle physics, and related areas of modern physics research. Its investigation into effective hadron masses and couplings contributes to the understanding of nuclear matter, a central topic in modern nuclear physics.
