Alternative Experimental Protocol for a PBR-Like Result

Pusey, Barrett and Rudolph (PBR) have recently proven an important new theorem in the foundations of quantum mechanics. Here we propose alternative experimental protocols which lead to the PBR result for a special case and a weaker PBR-like result generally. Alternative experimental protocols support the assumption of measurement independence required for the PBR theorem.Comment: 4 pages, 1 figur

Linear Collider Physics

Studies of the physics potential of the Future Linear Collider are establishing a broad programme which will start in the region of 350 to 500 GeV C. of M. energy. The main goal is to understand why the standard model works; by studying the properties of the Higgs sector, if it is within reach, and by exploring the complex world of Supersymmetry, if it is real. If the Higgs boson is not found soon, then the Linear Collider can test the standard model with high precision measurements, both at energies approaching 1 TeV and with high statistics at the Z0.Comment: 12 pages, 4 figures, to be published in Proceedings of La Thuile 200

Two Photon Physics at LEP2; including data Monte-Carlo comparison

A partisan review of some of the most important $\gamma\gamma$ channels accessible at LEP 2, with special stress on the measurement of the photon structure function $F_{2}^{\gamma}$ and on associated problems with Monte Carlo modelling.Comment: 7 pages including 5 figures. Invited talk given at the LEP2 Phenomenology Workshop, Oxford, U.K., 14 April 199

Measuring Fine Tuning In Supersymmetry

The solution to fine tuning is one of the principal motivations for supersymmetry. However constraints on the parameter space of the Minimal Supersymmetric Standard Model (MSSM) suggest it may also require fine tuning (although to a much lesser extent). To compare this tuning with different extensions of the Standard Model (including other supersymmetric models) it is essential that we have a reliable, quantitative measure of tuning. We review the measures of tuning used in the literature and propose an alternative measure. We apply this measure to several toy models and the MSSM with some intriguing results.Comment: Submitted for the SUSY07 proceeding

Photon Structure and gamma-gamma Physics

The LEP experiments are making real progress in understanding the structure of the photon, though the results do not yet give such clear demonstrations of QCD in action as the proton structure has done. Other new results are reported, including QED related effects and $\gamma \gamma \to Resonances$, from LEP and from CLEO II.Comment: 16 pages, 15 figures, Contribution to "Physics in Collision", Frascati, June 18-19, 199
