Resumen

La producción de Λ y K0s se ha estudiado en colisiones p+S y S+S de 200 GeV/nucleón en la cámara de flujo continuo del experimento NA35 del SPS del CERN. Se observó un aumento significativo de las multiplicidades de todas las partículas extrañas observadas en relación con los hadrones negativos en las colisiones S+S centrales, en comparación con las colisiones top+p y p+S. Estas últimas colisiones no muestran un aumento general (relativo) de la extrañeza sobre p+p, pero las distribuciones de rapidez y las multiplicidades hadrónicas indican cierta producción secundaria en cascada de partículas Λ en las colisiones p+S y p+Au. Se determinó que la polarización Λ en las colisiones S+S centrales es compatible con cero en top T = 2 GeV/c.
