摘要：
We discuss the implications of recently discovered strange tribaryons in He-4(stopped-K-, p) S-0(3115) and He-4(stopped-K- n) S-1(3140) within the framework of deeply bound K states formed on shrunk nuclear cores. S-1(3140) corresponds to T = 0 ppnK(-), whereas S-0(3115) to T = 1 pnnK(-), which is an isobaric analog state of pppK(-), predicted previously. The observed binding energies can be accounted for by including the relativistic effect and by invoking a medium-enhanced (K) over barN interaction by 15%. We propose various experimental methods to further study these and related bound systems. (c) 2005 Elsevier B.V. All rights reserved.
