Query: Reduced LHC constraints for higgsino-like heavier electroweakinos   As a sequel to our earlier work on wino-dominated $\tilde \chi_1^{\pm}$ and
$\tilde \chi_2^{0}$ (wino models), we focus on the pMSSM models where $\tilde
\chi_1^{\pm}$ and $\tilde \chi_{2,3}^{0}$ are either higgsino dominated
(higgsino models) or admixtures of significant amount of higgsino and wino
components (mixed models), with or without light sleptons. The LHC constraints
in the trilepton channel are significantly weaker even in the presence of light
sleptons, especially in the higgsino models, compared to those mostly studied
by the LHC collaborations with wino-dominated $\tilde \chi_1^{\pm}$ and $\tilde
\chi_2^{0}$. The modes $\tilde \chi_{2,3}^{0}\rightarrow h~\tilde\chi_1^{0}$
with large branching ratios (BRs) are more common in the higgsino models and
may produce spectacular signal in the LHC Run-II. In a variety of higgsino and
mixed models we have delineated the allowed parameter space due to the LHC
constraints, the observed Dark Matter (DM) relic density of the universe, which
gets contributions from many novel DM producing mechanisms i.e., the
annihilation/coannihilation processes that lead to the correct range of relic
density, and the precise measurement of the anomalous magnetic moment of the
muon. In the higgsino models many new DM producing mechanisms, which are not
allowed in the wino models, open up. We have also explored the prospects of
direct and indirect detection of DM in the context of the LUX and IceCube
experiments respectively. In an extended model having only light gluinos in
addition to the electroweak sparticles, the gluinos decay into final states
with multiple taggable b-jets with very large BRs. As a consequence, the
existing ATLAS data in the $0l$ + jets (3b) + $E\!\!\!\!/_T$ channel provide
the best limit on $m_{\tilde g}$ ($\approx$ 1.3 TeV). Several novel signatures
of higgsino models for LHC Run-II and ILC have been identified.
