K ∗ ( 892 ) production in Au + Au and pp collisions at √ sNN = 200 GeV at STAR

0 Production in Relativistic Heavy Ion Collisions at √ sNN = 130 GeV

Preliminary results on the K * (892) 0 → πK production using the mixed-event technique are presented. The measurements are performed at mid-rapidity by the STAR detector in √ s NN = 130 GeV Au-Au collisions at RHIC. The K * 0 to negative hadron, kaon and Φ ratios are obtained and compared to the measurements in e + e − , pp and ¯ pp at various energies.

Energy Dependence of Short and Long-range Multiplicity Correlations in Au+au Collisions from Star

A general overview of the measurement of long-range multiplicity correlations measured by the STAR experiment in Au+Au collisions at RHIC is presented. The presence of long-range correlations can provide insight into the early stages, and the type of matter produced in, these collisions. These measurements have been made in Au+Au collisions at √ sNN = 200 and 62.4 GeV. These results indicate a ...

Au+Au and pp collisions from STAR

We present the results for the measurement of φ meson production in √ sNN = 200 GeV Au+Au and pp collisions at the Relativistic Heavy Ion Collider (RHIC). Using the event mixing technique, spectra and yields are obtained from the φ → KK decay channel for five centrality bins in Au+Au collisions and in pp collisions. We observe that the spectrum shape in Au+Au collisions depends weakly on the ce...

Λ̄–hyperon global polarization in Au+Au collisions at RHIC

We present the Λ̄–hyperon global polarization in Au+Au collisions at √ sNN = 62 GeV and 200 GeV measured with the STAR detector at RHIC. The observed Λ̄–hyperon global polarization is consistent with zero, what is in agreement with recent measurements of Λ global polarization, as well as φ(1020) and K(892) vector mesons spin alignment with respect to the reaction plane. The possible dependence of...
