We may also view the measurement problem as the quest for a generic
superselection rule (the selection of the preferred basis): the
prediction of the preferred basis of a given experiment (what does not
seem to be given by the current QM postulates). However, I do not know
if one has ever proved that such a rule exists (either by tests or by a
theorem).

I may propose you the following papers:

* Elements of Environmental Decoherence, Joos 1999,
arXiv:quant-ph/9908008 (short one)
* Decoherence, the Measurement Problem, and Interpretations of Quantum
Mechanics, Schlosshauer 2003, arXiv:quant-ph/0312059 (extensive review
of the problem end of 2003, very complete and lot of pointers to other
papers)

If someone has other recent papers, do not hesitate to post them : ).
