摘要We study the lambda(+)(c) -> pi(0)phi p decay by considering a triangle singularity mechanism. In this mechanism, the lambda(c) decays into the K*sigma*(1385), the sigma*(1385) decays into the pi degrees sigma (or A), and then the K*sigma (or A) interact to produce the phi p in the final state. This mechanism produces a peak structure around 2020 MeV. In addition, the possibility that there is a hidden-strange pentaquark-like state is also considered by taking into account the final state interactions of K*lambda ,K*sigma, and phi p. We conclude that it is difficult to search for the hidden-strange analogue of the P-c states in this decay. However, we do expect nontrivial behavior in the phi p invariant mass distribution. The predictions can be tested by experiments such as BESIII, LHCb and Belle-II. (c) 2017 The Author(s). Published by Elsevier B.V.
