star focus:
Phi Meson and Strangeness Enhancement at RHIC
Highlights from the STAR paper:
Energy and system size dependence of phi-meson
production in Cu+Cu and Au+Au collisions.
Submitted for publication to Physics Letters B.
|
In a Quark-Gluon Plasma, thermal s and sbar
quarks can be produced by gluon-gluon interactions. These
interactions could
occur very rapidly and the s-quark abundance
would equilibriate. During hadronisation, the s
and sbar quarks from the plasma coalesce to form
phi-mesons. Production by this process is
not suppressed as per the OZI (Okubo-Zweig-Izuka)
rule. This, coupled with large abundances of
strange quarks in the plasma, may lead to a
dramatic increase in the production of phi-mesons
and other strange hadrons relative to non-QGP
p+p collisions.

Congratulations to Monika Sharma from Panjab University,
Chandigrah, India for successfully defending her Ph.D
thesis based on photon
multiplicity measurements and net charge fluctuations in
STAR.
Monika is currently a post doctoral fellow at
Wayne State University.

Congratulations Saskia Mioduszewski of the
Cyclotron Institute for being awarded the
2009 Maria Goeppert Mayer Award by the American
Physical Society "for her pioneering contributions
to the observation of jet quenching and her continuing
efforts to understand high- p_T
phenomena in relativistic heavy- ion collisions."
The award was established in 1985 to recognize
and enhance outstanding achievement by a woman
physicist in the early years of her career, and
to provide opportunities for her to present these
achievements to others through public lectures
in the spirit of Maria Goeppert Mayer.

Congratulations to Paul Sorensen for receiving the APS 2008
George E. Valley, Jr. Prize. The award
recognizes Paul's contributions "in the discovery
of quark number scaling in the elliptic flow
of hadrons in nucleus-nucleus collisions, and its
interpretation showing the relevance of quark
degrees of freedom in heavy ion interactions."
Valley prize is presented biennially to recognize
one individual in the early stages of his or
her career for an outstanding scientific
contribution to physics that is deemed to have
significant potential for a dramatic impact on
the field. The prize, which carries an award of
$20,000, will be presented at the APS April 2009
meeting in Denver, at a special Ceremonial
Session.
