Query: $\Xi(1690)^-$ production in the $K^-p\to K^+K^-\Lambda$ reaction process
  near threshold   We investigate $\Xi(1690)^-$ production from the $K^-p\to K^+K^-\Lambda$
reaction within the effective Lagrangian approach at the tree-level Born
approximation. We consider the $s$- and $u$-channel $\Sigma/\Lambda$ ground
states and resonances for the $\Xi$-pole contributions, in addition to the
$s$-channel $\Lambda$, $u$-channel nucleon pole, and $t$-channel $K^-$-exchange
for the $\phi$-pole contributions. The $\Xi$-pole includes $\Xi(1320)$,
$\Xi(1535)$, $\Xi(1690)(J^p=1/2^-)$,and $\Xi(1820)(J^p=3/2^-)$. We calculate
the Dalitz plot density of $(d^2\sigma/dM_{K^+K^-}dM_{K^-\Lambda}$ at 4.2
GeV$/c$) and the total cross sections for the $K^-p\to K^+K^-\Lambda$ reaction
near the threshold. The calculation results are in good agreement with
previously acquired experimental data. Using the parameters from the fit, we
present the total and differential cross sections for the two-body $K^-p\to
K^+\Xi(1690)^-$ reaction near the threshold. In our calculation, a strong
enhancement at backward $K^+$ angles is predicted because of the dominant
$u$-channel contribution. We also demonstrate that the Dalitz plot analysis for
$p_{K^-}=1.915 -- 2.065$ GeV/c enables us to access direct information
regarding $\Xi(1690)^-$ production, which can be tested by future $K^-$ beam
experiments. The possible spin-parity states of $\Xi(1690)^-$ are briefly
discussed as well.
