Λ\(\bar \Lambda\) longitudinal polarization: A signature for the formation of a quark-gluon plasma in heavy ion collisions

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The high relative abundance ofs \(\bar s\) quarks in the quark-gluon plasma will result in peculiar hadronization ratios whereby the Ξ/Λ ratio should be much higher than in usual processes. As a result the Λ(\(\bar \Lambda\)) should exhibit a sizeable longitudinal polarization due to their importantΞ(\(\bar \Xi\)) filiation. Discussing such spin effect, the report starts with the determination of theW spin, a recent and successful application of the helicity formalism.
