On the nonextendibility of quantum theory
I will present a recent theorem that asserts that there cannot exist an "extension of quantum theory" that allows us to make more informative predictions about future measurable events (e.g., whether a horizontally polarized photon passes a polarization filter with a given orientation) than standard quantum theory.

Phenomenology of spontaneous wavefunction collapse models
Angelo Bassi
University of Trieste
Models of spontaneous wave function collapse make predictions, which are different from those of standard quantum mechanics. Indeed, these models can be considered as a rival theory, against which the standard theory can be tested, in pretty much the same way in which parametrized postNewtonian gravitational theories are rival theories of general relativity. The predictions of collapse models almost coincide with those of standard quantum mechanics at the microscopic level, as these models have to account for the microscopic world, as we know it.
Ontology of collapse theories
Wayne Myrvold
Western University
The textbook collapse postulate says that, after a measurement, the quantum state of the system on which the measurement was performed , and becomes an eigenstate of the observable measured.
Collapse and Consequences
Philip Pearle
University of Hamilton
I shall give an introduction to conceptual ideas and equations of the CSL (Continuous Spontaneous Localization) theory of dynamical wave function collapse. Then, I shall discuss various applications of the theory.

Path Integrals, Reality and Generalizations of Quantum Theory
Adrian Kent
University of Cambridge
I describe some tentative new ideas on modified
versions of quantum theory motivated by the path integral formalism, and on
other generalizations, and comment on possible experimental implications.
