We study the naturalness, dark matter, and muon anomalous magnetic moment inthe Supersymmetric Standard Models (SSMs) with a pseudo-Dirac gluino (PDGSSMs)from hybrid $F-$ and $D-$term supersymmetry (SUSY) breakings. To obtain theobserved dark matter relic density and explain the muon anomalous magneticmoment, we find that the low energy fine-tuning measures are larger than about30 due to strong constraints from the LUX and PANDAX experiments. Thus, tostudy the natural PDGSSMs, we consider multi-component dark matter and then therelic density of the lighest supersymmetric particle (LSP) neutralino issmaller than the correct value. We classify our models into six kinds: (i) CaseA is a general case, which has small low energy fine-tuning measure and canexplain the anomalous magnetic moment of the muon; (ii) Case B with the LSPneutralino and light stau coannihilation; (iii) Case C with Higgs funnel; (iv)Case D with Higgsino LSP; (v) Case E with light stau coannihilation andHiggsino LSP; (vi) Case F with Higgs funnel and Higgsino LSP. We study theseCases in details, and show that our models can be natural and consistent withthe LUX and PANDAX experiments, as well as explain the muon anomalous magneticmoment. In particular, all these cases except the stau coannihilation can evenhave low energy fine-tuning measures around 10.
