英文摘要	New resonance Lambda(c)(2860)(+), reported by the LHCb Collaboration, is a key to establish the D-wave charmed and charmed-strange baryon families. In this work, we first carry out an analysis of mass spectra of the lambda-mode excited charmed and charmed-strange baryon states, which may reveal the relation of Lambda(c)(2860)(+), Lambda(c)(2880)(+), Xi(c)(3055)(+), Xi(c)(3080)(+) and, i.e.,Lambda(c)(2860)(+), Lambda(c)(2880)(+) and can form a D-wave doublet [3/2(+), 5/2(+)] , while Xi(c)(3055)(+), and Xi(c)(3080)(+) are the strange partners of Lambda(c)(2860)(+) and Lambda(c)(2880)(+), respectively. Further study of their two-body Okubo-Zweig-Iizuka-allowed decays supports Lambda(c)(2860)(+) and Xi(c)(3055)(+) as the D-wave charmed and charmed-strange baryons, respectively, with J(P) = 3/2(+). For Lambda(c)(2880)(+) and Xi(c)(3080)(+), however, there exist some difficulties under the D-wave assignment with J(P) = 5/2(+), since the experimental widths, and some ratios of partial width of Lambda(c)(2880)(+) and Xi(c)(3080)(+), cannot be reproduced in our calculation.
