Abstract

A summary of BRAHMS results is presented. Emphasis is placed on data for which measurements at forward rapidities are necessary for interpretation. This includes measurements of spectra over a wide range of y and transverse momentum, yields, stopping, quark chemistry and high pt suppression in both Au+Au and d+Au collisions at = 200 GeV.

Keywords: Quark chemistry; rapidity density; stopping; high pt suppression.

 

Resumen

Se presenta un resumen de los resultados obtenidos en BRAHMS, enfatizando en aquellos datos cuya interpretación requiere las medidas de las rapideces. Esto incluye mediciones del espectro sobre un amplio rango de "y" y momento transverso, productos, frenados, química de cuarks y alta supresión de Pt en colisiones de Au + Au y d + Au a = 200GeV.

Descriptores: Química de cuarks; densidad de rapideces; frenado; alta supresion pt.
