Query: Evidence for the decays of $\Lambda^+_{c}\to\Sigma^+\eta$ and
  $\Sigma^+\eta^\prime$   We study the hadronic decays of $\Lambda_{c}^{+}$ to the final states
$\Sigma^{+}\eta$ and $\Sigma^+\eta^\prime$, using an $e^{+}e^{-}$ annihilation
data sample of 567 pb$^{-1}$ taken at a center-of-mass energy of 4.6 GeV with
the BESIII detector at the BEPCII collider. We find evidence for the decays
$\Lambda_{c}^{+}\rightarrow\Sigma^{+}\eta$ and $\Sigma^+\eta^\prime$ with
statistical significance of $2.5\sigma$ and $3.2\sigma$, respectively.
Normalizing to the reference decays $\Lambda_c^+\to\Sigma^+\pi^0$ and
$\Sigma^+\omega$, we obtain the ratios of the branching fractions
$\frac{{\mathcal B}(\Lambda_c^+\to\Sigma^+\eta)}{{\mathcal
B}(\Lambda_c^+\to\Sigma^+\pi^0)}$ and $\frac{{\mathcal
B}(\Lambda_c^+\to\Sigma^+\eta^\prime)}{{\mathcal
B}(\Lambda_c^+\to\Sigma^+\omega)}$ to be $0.35 \pm 0.16 \pm 0.03$ and $0.86 \pm
0.34 \pm 0.07$, respectively. The upper limits at the 90\% confidence level are
set to be $\frac{{\mathcal B}(\Lambda_c^+\to\Sigma^+\eta)}{{\mathcal
B}(\Lambda_c^+\to\Sigma^+\pi^0)}<0.58$ and $\frac{{\mathcal
B}(\Lambda_c^+\to\Sigma^+\eta^\prime)}{{\mathcal
B}(\Lambda_c^+\to\Sigma^+\omega)}<1.2$. Using BESIII measurements of the
branching fractions of the reference decays, we determine $\mathcal
B({\Lambda_{c}^{+}\rightarrow\Sigma^{+}\eta})=(0.41\pm0.19\pm0.05)\%$
($<0.68\%$) and $\mathcal
B({\Lambda_{c}^{+}\rightarrow\Sigma^{+}\eta'})=(1.34\pm0.53\pm0.21)\%$
($<1.9\%$). Here, the first uncertainties are statistical and the second
systematic. The obtained branching fraction of $\Lambda_c^+\to\Sigma^+\eta$ is
consistent with the previous measurement, and the branching fraction of
$\Lambda_{c}^{+}\rightarrow\Sigma^{+}\eta^{\prime}$ is measured for the first
time.
