| contents | While there has been a lot of progress in developing a
formalism for the study of quarkonia in QGP, a nonperturbative
study is still difficult. For bottomonia, where the system size
is much less than the inverse temperature, the interaction of the
system with the medium can be approximated by a dipole interaction with
the color electric field. The decay of the quarkonia can be connected to
a correlation function of the color electric field.
We present preliminary results from a lattice study of the relevant color
electric field correlator. The structure of the correlator, and its
difference from the corresponding correlator studied for heavy quark
diffusion, is discussed. |
