130. from Silicon-, via Gas-, towards Foil tracking detectors

Dr Harry van der Graaf van der Graaf (Nikhef)

Oral

The GridPix detector is a Time Projection Chamber with a pixelized readout anode. With a drift gap of 1 mm, the gas layer functions as the Si sensor of a Si pixel or Si strip detector. With a drift gap of 20 mm, GridPix can accurately reconstruct the path of, and measure the energy of photo- and Compton electrons associated with photon absorption. With this information, the polarization of...

2. A New High-Sensitivity Muon-to-Electron Conversion Search at Fermilab

Dr Robert Bernstein Bernstein (Fermilab)

Searches for symmetry violations

Oral

Mu2e will search for coherent, neutrino-less conversion of muons into electrons in the field of a nucleus, witha sensitivity improvement of a factor of 10,000 over existing limits. Such a lepton flavor-violating reaction probes new physics at a scale unavailable by direct searches at either present or planned high energy colliders. The physics motivation for Mu2e will be presented, as...

72. Ultraslow muonium for a muon beam of ultrahigh quality

Dr David Taqqu (Swiss federal institute of technology, Zurich)

14/10/2010, 12:00

Advanced muon sources

Oral

A new pathway for the achievement of a pulsed slow muon beam by the muonium ionization method is proposed. It uses a thin superfluid helium target in which the stopped muons are pulled towards the liquid vapor interface where they form muonium atoms in the bubble state. As they reach the interface they are emitted and slow down in a vapor layer from which they exit at low velocity and low...

60. A novel mu to 3e experiment

Prof. Andre Schoening (University Heidelberg, Institute of Physiscs)

14/10/2010, 12:20

Low energy precision tests of the Standard Model

Oral

Design studies for an experiment searching for the lepton flavour violating decay mu to 3e are presented. The detector concept is based on thin layers of silicon sensors with fast readout. The aim is to reach an experimental sensitivity of 1e-16 for this process, which is an improvement by factor 10000 compared to the existing limit.

80. Can CP-violation be observed in heavy-ion collisions?

Prof. I. B. Khriplovich (Budker Institute of Nuclear Physics, 630090, Novosibirsk, Russia)

14/10/2010, 12:40

Searches for symmetry violations

Oral

We demonstrate that, at least at present, there is no convincing way to detect CP-violation in heavy-ion collisions.
