On June 18, The
Phobos collaboration participated in a colloquium and press conference at BNL during
which all 4 RHIC experiments presented exciting results from the deuteron-gold (d+Au)
data taken earlier in 2003. More information about the event including links to
news releases and the talks presented can be found at the RHIC and BNL web
pages. The Phobos presentation is here.
In addition, Phobos
was one of 3 experiments submitting an account of the new analysis to Physical Review
Letters. The d+Au data strongly suggest that the high transverse momentum suppression
seen in Au+Au data is not due to initial state effects but is instead due to the
formation of some exotic state of matter, the nature of which will be the subject of
intense future study. (Note that while the suppression was first seen in 130 GeV Au+Au
by Phenix, the first submitted publication
of Au+Au spectra showing this suppression at the full RHIC energy of 200 GeV came from
Phobos.)
The recently
submitted Phobos data are unique in that they describe the detailed
centrality dependence of the d+Au spectra, an aspect which allows more
quantitative comparison to various theoretical models.
