Using the data obtained with SKAT bubble chamber, the total yields of $K^+(892)$, $Sigma^+(1385)$ and $Sigma^0$ are estimated for the first time in neutrino-induced reactions at moderate energies ($<E_{ u}>$ = 10.4 GeV). It is shown, that the recently observed cite{ref1,ref2} enhancement of the $K^0$ and $Lambda$ yields in $ u A$ interactions (as compared to $ u N$ interactions) is contributed only slightly by the $K^+(892)$ and $Sigma^+(1385)$ production, respectively. The decay contribution to the $K^0$ and $Lambda$ yields is found to be in qualitative agreement with higher energy ($<E_ u> geq$ 40 GeV) data. It is shown, that the energy dependence of the $K^+(892)$ mean multiplicity in $ u N$ interactions is approximately linear in the range of $<E_{ u}> approx$ 10-60 GeV, while that for $Sigma^0$ in $ u A$ interactions (for $A$ = 20-21) is approximately logarithmic in the range of $<E_{ u}> approx$ 10-150 GeV.

The total yields of the all well-established light mesonic resonances (up to the $phi$(1020) meson) are estimated in neutrinonuclear interactions at < E_nu > = 10 GeV, using the data obtained with SKAT bubble chamber. For some resonances, the yields in the forward and backward hemispheres in the hadronic c.m.s. are also extracted. From the comparison of the obtained and available higher-energy data, an indication is obtained that the resonance yields rise almost linearly as a function of the mean mass < W > of the neutrinoproduced hadronic system. The fractions of pions originating from the light resonance decays are inferred.
Differential cross sections for $gamma p to K^+Lambda(1405)$ and $gamma p to K^+Sigma^0(1385)$ reactions have been measured in the photon energy range from 1.5 to 2.4 GeV and the angular range of $0.8<cos(Theta)<1.0$ for the $K^+$ scattering angle in the center-of-mass system. This data is the first measurement of the $Lambda(1405)$ photoproduction cross section. The lineshapes of LamS measured in $Sigma^+pi^-$ and $Sigma^-pi^+$ decay modes were different with each other, indicating a strong interference of the isospin 0 and 1 terms of the $Sigmapi$ scattering amplitudes. The ratios of LamS production to SigS production were measured in two photon energy ranges: near the production threshold ($1.5<E_gamma<2.0$ GeV) and far from it ($2.0 <E_gamma<2.4$ GeV). The observed ratio decreased in the higher photon energy region, which may suggest different production mechanisms and internal structures for these hyperon resonances.
The aim of the present analysis is to determine the relative production cross sections of the $Lambda$(1405) and $Sigma(1385)^{0}$ resonances in p+p collisions at E$_{kin}$=3.5 GeV measured with HADES. Upper and lower limits have been determined for the ratio $sigma_{(Sigma(1385)^{0}+p+K^{+})}/sigma_{(Lambda(1405)+p+K^{+})}=0.76_{-0.26}^{+0.54}$. The knowledge of this ratio is an essential input for the analysis of the decay $Lambda(1405)rightarrowSigma^{pm}pi^{mp}$, where an unambiguous separation of the $Lambda$(1405) and $Sigma(1385)^{0}$ signals is not possible.

We report branching fraction measurements of four decay modes of the $Lambda_{c}^{+}$ baryon, each of which includes an $eta$ meson and a $Lambda$ baryon in the final state, and all of which are measured relative to the $Lambda_{c}^{+} rightarrow p K ^{-} pi^{+}$ decay mode. The results are based on a $980~mathrm{fb^{-1}}$ data sample collected by the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. Two decays, $eta Sigma^{0} pi^{+}$ and $Lambda(1670) pi^{+}$, are observed for the first time, while the measurements of the other decay modes, $Lambda_{c}^{+} rightarrow etaLambdapi^{+}$ and $etaSigma(1385)^{+}$, are more precise than those made previously. We obtain $mathcal{B}(Lambda_{c}^{+} rightarrow eta Lambda pi^{+})/mathcal{B}(Lambda_{c}^{+} rightarrow p K^{-} pi^{+})$ = $0.293 pm 0.003 pm 0.014$, $mathcal{B}(Lambda_{c}^{+} rightarrow eta Sigma^{0} pi^{+})/mathcal{B}(Lambda_{c}^{+} rightarrow p K^{-} pi^{+})$ = $0.120 pm 0.006 pm 0.006$, $mathcal{B}(Lambda_{c}^{+} rightarrow Lambda(1670) pi^{+}) times mathcal{B}(Lambda(1670) rightarrow eta Lambda)/mathcal{B}(Lambda_{c}^{+} rightarrow p K^{-} pi^{+})$ = $(5.54 pm 0.29 pm 0.73 ) times 10^{-2}$, and $mathcal{B}(Lambda_{c}^{+} rightarrow eta Sigma(1385)^{+})/mathcal{B}(Lambda_{c}^{+} rightarrow p K^{-} pi^{+})$ = $0.192 pm 0.006 pm 0.016$. The mass and width of the $Lambda(1670)$ are also precisely determined to be $1674.3 pm 0.8 pm 4.9~{rm MeV}/c^{2}$ and $36.1 pm 2.4 pm 4.8~{rm MeV}$, respectively, where the uncertainties are statistical and systematic, respectively.
Using a data sample of 980 fb$^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider, we study the processes of $Xi^0_cto Lambdabar K^{*0}$, $Xi^0_cto Sigma^0bar K^{*0}$, and $Xi^0_cto Sigma^+K^{*-}$ for the first ti me. The relative branching ratios to the normalization mode of $Xi^0_ctoXi^-pi^+$ are measured to be $${cal B}(Xi^0_cto Lambdabar K^{*0})/{cal B}(xicto Xi^-pi^+)=0.18pm0.02({rm stat.})pm0.01({rm syst.}),$$ $${cal B}(Xi^0_cto Sigma^0bar K^{*0})/{cal B}(xicto Xi^-pi^+)=0.69pm0.03({rm stat.})pm0.03({rm syst.}),$$ $${cal B}(Xi^0_cto Sigma^+K^{*-})/{cal B}(xicto Xi^-pi^+)=0.34pm0.06({rm stat.})pm0.02({rm syst.}),$$ where the uncertainties are statistical and systematic, respectively. We obtain %measure the branching fractions of $Xi^0_cto Lambdabar K^{*0}$, $Xi^0_cto Sigma^0bar K^{*0}$, and $Xi^0_cto Sigma^+K^{*-}$ to be $${cal B}(Xi^0_cto Lambdabar K^{*0})=(3.3pm0.3({rm stat.})pm0.2({rm syst.})pm1.0({rm ref.}))times10^{-3},$$ $${cal B}(Xi^0_cto Sigma^0bar K^{*0})=(12.4pm0.5({rm stat.})pm0.5({rm syst.})pm3.6({rm ref.}))times10^{-3},$$ $${cal B}(Xi^0_cto Sigma^+K^{*-})=(6.1pm1.0({rm stat.})pm0.4({rm syst.})pm1.8({rm ref.}))times10^{-3},$$ where the uncertainties are statistical, systematic, and from ${cal B}(xic to Xi^-pi^+)$, respectively. The asymmetry parameters $alpha(Xi^0_cto Lambdabar K^{*0})$ and $alpha(Xi^0_cto Sigma^+K^{*-})$ are $0.15pm0.22({rm stat.})pm0.04({rm syst.})$ and $-0.52pm0.30({rm stat.})pm0.02({rm syst.})$, respectively, where the uncertainties are statistical followed by systematic.
