Nominations are sought for the 2019 Sambamurti Memorial Lecture at Brookhaven
National Laboratory. This is a prize lectureship established in memory of
a young high energy experimentalist working on rare kaon decays at the
BNL AGS, who died in 1992. It is to be awarded yearly to a young (under 40)
high energy or heavy ion experimentalist of outstanding achievement. The
lecture, which should describe the work for which the lecturer is being honored,
is to be delivered to students working at BNL during the summer. The 2019
prize is $500. Please send nominations to John Haggerty, Physics 510A,
BNL, Upton, NY 11973, or firstname.lastname@example.org.
The Quark Gluon Plasma (QGP) filled the universe in the first microsecond after the Big Bang and today is routinely recreated in high energy nuclear collisions at RHIC and the LHC. While experiments have revealed an array of surprising QGP properties, such as perfect fluidity, extreme vorticity, and near total opaqueness to hard scattered quarks and gluons, the detailed physics that gives rise to these properties remains a focus of forefront research. Heavy quarks, particularly the very heavy beauty quark, provide the means to clarify the connection between the microscopic physics of the QGP and its larger scale properties. Beauty quarks – or b-quarks – are produced rarely in collisions at RHIC, and the planned sPHENIX experiment will be equipped with a high rate vertex tracker enabling precision measurements of b-quark observables, such as B-meson suppression and flow, the differential suppression of Upsilon states and a number of observables related to b-quark jets. These b-quark probes will provide crucial information about the microscopic description of QGP at RHIC energies. In this talk, I will explain b-quark physics in the QGP, current measurements, the program at the planned sPHENIX experiment and its relevance to the future Electron Ion Collider.
