This page provides information on Jefferson Lab Hall A experiments E98-108, "Electroproduction of Kaons up to Q2 = 3 (GeV/c)2 " and E94-107, "High Resolution 1p-Shell Hypernuclear Spectroscopy". The spokespersons on the two experiments are:
Experiment E98-108 measures kaon production cross sections, picking a specific reaction mechanism via a separation of response functions in the exclusive H(e,e'K+)Y reaction. This experiment will measure how kaons are electromagnetically produced -- meaning which production mechanisms contribute and to what extent.
Current knowledge is unsatisfactory with no systematic separation
of either the competing production mechanisms or the resulting
response functions. Multi-parameter models based on hadron dynamics
(QHD) have attempted to explain the existing data, but a wider
kinematical region has to be accessed in order to constrain the models
The longitudinal and transverse response functions will be
separated by detecting kaons along the direction of the virtual
photon, where only these terms contribute to the cross section. For
