摘要

The lowest order constrained variational method is reformulated to find the equation of state of hypernuclear matter. For the nucleon-nucleon interaction we employed the well-known Argonne V18 (AV18) interaction. The equation of state is calculated using two-body central potentials for Lambda N and Lambda Lambda interactions that are determined in order to reproduce the experimental data on single- and double-Lambda hypernuclei. For the odd-state part of the Lambda Lambda interaction, which is not known due to the lack of experimental data, a proposed repulsive and attractive potential is employed to calculate the equation of state. It is shown that the presence of Lambda in the hypernuclear matter produces a strong softening of the equation of state. The results are compared with similar calculations with another variational method. The state-dependent energy as well as central and tensor correlation functions are studied up to J = 2 for each JLSTMT channel where related to total (J), orbital (L) and spin (S) angular momentum and isospin (T) and the third component of isospin (MT) respectively for Lambda N and Lambda Lambda interactions. Furthermore, the effect of baryon density and hyperon density as well as the type of hyperon-hyperon interaction on the two-body correlation functions are investigated.
