Title: Precision measurement of the $$\Xi^0$$ mass and the branching ratios of the decays $$\Xi^0\rightarrow\Lambda\gamma$$ and $$\Xi^0 \rightarrow\Sigma^0\gamma$$

Abstract

A new precision measurement of the Ξ⁰ mass has been performed at the NA48 experiment at the CERN SPS. The value obtained is [1314.82±0.06 (stat.) ±0.2 (syst.)] MeV/c². The branching ratios of Ξ⁰ radiative decays have been measured as: Br( Ξ⁰ → Λγ) = [1.90 ± 0.34(stat.) ± 0.19(syst.)] · 10^-3 and Br(Ξ⁰ → Σ⁰γ) = [3.14 ± 0.76(stat.) ± 0.32(syst.)] · 10^-3 .

Evidence of a structure in $$\bar{K}^{0} \Lambda _{c}^{+}$$ consistent with a charged $$\Xi _c(2930)^{+}$$, and updated measurement of $$\bar{B}^{0} \rightarrow \bar{K}^{0} \Lambda _{c}^{+} \bar{\Lambda }_{c}^{-}$$ at Belle

Journal Article Li, Y. B. ; Shen, C. P. ; Adachi, I. ; ... - European Physical Journal. C, Particles and Fields

We report evidence for the charged charmed-strange baryon $\Xi _{c}(2930)^+$ with a signal significance of 3.9$\sigma $ with systematic errors included. The charged $\Xi _{c}(2930)^+$ is found in its decay to $K_{S}^{0} \Lambda _{c}^+$ in the substructure of $\bar{B}^{0} \rightarrow K^{0}_{S} \Lambda _{c}^{+} \bar{\Lambda }_{c}^{-}$ decays. The measured mass and width are $[2942.3 \pm 4.4 ({\mathrm{stat.}}) \pm {1.5}({\mathrm{syst.}})]$ MeV/$c^{2}$ and $[14.8 \pm 8.8({\mathrm{stat.}}) \pm {2.5}({\mathrm{syst.}})]$ MeV, respectively, and the product branching fraction is $\mathcal{B}(\bar{B}^{0} \rightarrow \Xi _c(2930)^{+} \bar{\Lambda }_{c}^{-}) \mathcal{B}(\Xi _c(2930)^{+}\rightarrow \bar{K}^{0} \Lambda _{c}^{+})=[2.37 \pm 0.51 ({\mathrm{stat.}})\pm 0.31({\mathrm{syst.}})]\times 10^{-4}$.

Branching ratio and asymmetry for. Xi. sup 0 r arrow. Lambda. gamma

Journal Article James, C ; Heller, K ; Border, P ; ... - Physical Review Letters; (USA)

We have measured the branching ratio {Gamma}({Xi}{sup 0}{r arrow}{Lambda}{gamma})/{Gamma}({Xi}{sup 0}{r arrow}{Lambda}{pi}{sup 0}) to be (1.06{plus minus}0.12(stat){plus minus}0.11(syst)){times}10{sup {minus}3}. In 670 000 {Lambda}{gamma} candidates we found 116{plus minus}13 {Xi}{sup 0}{r arrow}{Lambda}{gamma} decays (background subtracted). These compare with 29 510 {Xi}{sup 0}{r arrow}{Lambda}{pi}{sup 0} events reconstructed from the {Lambda}{gamma}{gamma} sample. Monte Carlo studies gave the relative acceptances for the two processes. The helicity of the {Lambda} yielded the product of asymmetry parameters {alpha}({Lambda}{r arrow}{ital p}{pi}{sup {minus}}){alpha}({Xi}{sup 0}{r arrow}{Lambda}{gamma})=0.27{plus minus}0.28, which implies {alpha}({Xi}{sup 0}{r arrow}{Lambda}{gamma})=0.43{plus minus}0.44, where the uncertainty is all statistical.
