Nuclear medium effects on the properties of Λ(1405)
We study the Λ(1405) resonance with I ( J P ) = 0(1/2 − ) in the context of the pentaquark hypothesis in the nuclear medium. To explore the influence of the nuclear medium on the physical parameters of Λ(1405), we propose a molecular-type structure involving admixtures of K − p and K ¯ 0 n , correla...
