Typical comparisons of data from nuclear collisions to particle production models require a caveat for (anti)Lambda yields from experimental inability to separate the contributions of those yields from Sigma state decays. Recent analysis in…
While yields of Sigma0 have been measured in many different colliding systems, no measurements exist in high energy nuclear collisions. It also remains unexplored whether the relative yields of Sigma0 and Lambda change in collisions of…
The production of Lambda(1520) in p+p and Au+Au collisions provided by the RHIC at sqrt{s_NN}=200 GeV are investigated using the STAR detector. A preliminary Sigma(1385) signal is also shown. Models predict that a late rescattering phase in…
We report the first observation of the decay $\Lambda^+_{c}\rightarrow \Sigma^- \pi^+\pi^+\pi^0$, based on data obtained in $e^+e^-$ annihilations with an integrated luminosity of 567~pb$^{-1}$ at $\sqrt{s}=4.6$~GeV. The data were collected…

In p+p, d+Au, and Au+Au collisions at \sqrt{s_{NN}}=200 GeV with the STAR detector at RHIC, \Sigma(1385)\to\Lambda+\pi were measured using two techniques; three-particle mixing and a hybrid mixing technique. We present results from both of…
