Query: Measurements of Absolute Branching Fractions for
  $\Lambda^+_c\to\Xi^0K^+$ and $\Xi(1530)^0K^+$   We report the first measurements of absolute branching fractions for the
$W$-exchange-only processes $\Lambda^+_c\to\Xi^0K^+$ and
$\Lambda^+_c\to\Xi(1530)^0K^+$ with the double-tag technique, by analyzing an
$e^{+}e^{-}$ collision data sample, that corresponds to an integrated
luminosity of 567 pb$^{-1}$ collected at a center-of-mass energy of 4.6 GeV by
the BESIII detector. The branching fractions are measured to be
$\mathcal{B}(\Lambda^+_c\to\Xi^0K^+)=(5.90\pm0.86\pm0.39)\times10^{-3}$ and
$\mathcal{B}(\Lambda^+_c\to\Xi(1530)^0K^+)=(5.02\pm0.99\pm0.31)\times10^{-3}$,
where the first uncertainties are statistical and the second systematic. Our
results are more precise than the previous relative measurements.
