Status of the Jefferson Lab Eta Factory (JEF) experiment
ORAL
Abstract
The Jefferson Lab Eta Factory (JEF) experiment will leverage an upgraded GlueX
detector in Hall D at Jefferson Lab to use the production and subsequent decays
of η mesons to determine the u/d quark mass ratio, to set constraints on
new C-violating/P-conserving reactions, and to search for signatures of Beyond
Standard Model physics. In particular, the η→π0γγ channel
can be used to provide a window into chiral perturbation theory at
O(p6) and to search for lepto-phobic dark vector (B) bosons in
the reaction η→Bγ (B→π0γ) or dark scalar (S) bosons
in the reaction η→π0S (S→γγ). This channel requires
replacing the inner region of the Forward Calorimeter (FCAL) of the GlueX
detector with an array of 40×40 lead tungstate modules that will
provide a factor of two improvement in position and energy resolution
relative to the existing blocks.
This talk will summarize the experimental program and present the status of the
FCAL upgrade.
