Description
Because of their large mass, b quarks are expected to lose less energy
through qluon radiation than lighter quarks. This effect is most
pronounced for p_T << m_q. J/psi production from the B->J/psi decay
is a powerful observable to measure the nuclear modification of B
mesons in this p_T range. PHENIX has measured the yield of these
non-prompt J/psi's in Cu+Au collisions at 200 GeV at forward and
backward rapidity. This measurement was enabled by identifying the
secondary vertex of the B meson decay with the Forward Silicon Vertex
Detector (FVTX). The Cu+Au system studied is particularly interesting
due to the different admixtures of hot and cold nuclear matter effects
in the Cu- and Au-going directions.
