摘要In the present work, we apply the one-boson-exchange potential model to investigate the possibility of Y(2175) and eta(2225) as bound states of Lambda(Lambda) over bar(S-3(1)) and Lambda(Lambda) over bar(S-1(0)), respectively. We consider the effective potential from the pseudoscalar eta exchange and eta' exchange, the scalar sigma exchange, and the vector omega exchange and phi exchange. The eta- and eta'-meson-exchange potential is a repulsive force for the state S-1(0) and attractive for S-3(1). The results depend very sensitively on the cutoff parameter of the omega exchange (Lambda(omega)) and least sensitively on that of the phi exchange (Lambda(phi)). Our result suggests the possible interpretation of Y(2175) and eta(2225) as the bound states of Lambda(Lambda) over bar(S-3(1)) and Lambda(Lambda) over bar(S-1(0)), respectively.
