The Serendiptichord: Reflections on the collaborative design process between artist and researcher
The Serendiptichord is a wearable instrument, resulting from a collaboration crossing fashion, technology, music and dance. This paper reflects on the collaborative process and how defining both creative and research roles for each party led to a successful creative partnership built on mutual respect and open communication. After a brief snapshot of the instrument in performance, the instrument is considered within the context of dance-driven interactive music systems followed by a discussion on the nature of the collaboration and its impact upon the design process and final piece
Minimal Supergravity with m_0^2 < 0
We extend the parameter space of minimal supergravity to negative values of
m_0^2, the universal scalar mass parameter defined at the grand unified scale.
After evolving to the weak scale, all scalars can be non-tachyonic with masses
consistent with collider constraints. This region of parameter space is
typically considered excluded by searches for charged dark matter, since the
lightest standard model superpartner is a charged slepton. However, if the
gravitino is the lightest supersymmetric particle, the charged slepton decays,
and this region is allowed. This region provides qualitatively new
possibilities for minimal supergravity, including spectra with light sleptons
and very heavy squarks, and models in which the lightest slepton is the
selectron. We show that the m_0^2 < 0 region is consistent with low energy
precision data and discuss its implications for particle colliders. These
models may provide signals of supersymmetry in even the first year of operation
at the Large Hadron Collider.Comment: 16 page
