Z° factory makes ready

Tool-use observation makes far objects ready-to-hand.

Previous evidence has shown that active tool-use remaps agents' reaching space with far objects being perceived as reachable and graspable. To date, however, there is no evidence that tool-use observation might also be effective in reaching space remapping. The present six experiments show that not only performing but also observing tool actions may extend the representation of reaching space, ...

z-Tree: Zurich Toolbox for Ready-made Economic Experiments

Z-Tree (Zurich Toolbox for Ready-made Economic Experiments) is a software for developing and conducting economic experiments. The software is stable and allows to program almost any kind of experiments in a short time. In this article, I present the guiding principles behind the software design, its features, and its limitations.

Experimental Issues for Precision Electroweak Physics at a High-Luminosity Z Factory

We discuss the ultimate precision for ALR, and therefore for the weak mixing angle, at a high luminosity Linear Collider. Drawing on our experience at the SLC, and considering various machine parameter sets for the NLC and for TESLA, it emerges that a compromise between peak luminosity and precision will be a likely outcome. This arises due to the severe requirements on the uncertainty in the l...

Electroweak and CP violation physics at a Linear Collider Z-factory

A future linear collider such as TESLA may be able to run on the Z resonance with very high luminosity and polarised electron and positron beams. The possibilities of measuring electroweak quantities with high precision are investigated. Huge improvements with respect to the present precision can be expected, especially for the asymmetries ALR and Ab where beam polarisation can be exploited. Th...
