A neural network z-vertex trigger for Belle II
Sara Neuhaus, Sebastian Skambraks, Fernando Abudinén +8
We present the concept of a track trigger for the Belle II experiment, based on a neural network approach, that is able to reconstruct the z (longitudinal) position of the event ve…
Measurement of alpha_s in radiative hadronic events at OPAL
Jochen Schieck
Hadronic final states with a hard isolated photon are studied using data taken at centre-of-mass energies around $\Mz$ with the OPAL detector at LEP. The strong coupling $\as$ is e…
Track-based alignment for the ATLAS Inner Detector Tracking System
Jochen Schieck
We discuss the track-based alignment for the Inner Detector of the ATLAS experiment. After describing the main alignment method based on the minimization of hit residuals, we focus…
Measurement of the strong coupling alpha_S from the three-jet rate in e+e- - annihilation using JADE data
Jochen Schieck, Siegfried Bethke, Stefan Kluth +3
We present a measurement of the strong coupling alpha_S using the three-jet rate measured with the Durham algorithm in e+e- -annihilation using data of the JADE experiment at centr…
Angular analysis of the decay B->K*mumu and studies of mixing and CP-violation in the BS0 system with the ATLAS detector
Jochen Schieck
The measurement of B meson decay properties provides an alternative approach for searches for physics beyond the Standard Model. We present two different measurements performed wit…
DEPFET Pixels as a Vertex Detector for the Belle II Experiment
Jochen Schieck
Currently the heavy flavour factory KEKB located at the KEK accelerator centre in Tsukuba, Japan, is being upgraded to the Super KEKB factory, aiming for a substantially higher lum…
A z-Vertex Trigger for Belle II
Sebastian Skambraks, Fernando Abudinen, Yang Chen +8
The Belle II experiment will go into operation at the upgraded SuperKEKB collider in 2016. SuperKEKB is designed to deliver an instantaneous luminosity $\mathcal{L}=8\times10^{35}\…
Cait: analysis toolkit for cryogenic particle detectors in Python
Felix Wagner, Daniel Bartolot, Damir Rizvanovic +3
Cryogenic solid state detectors are widely used in dark matter and neutrino experiments, and require a sensible raw data analysis. For this purpose, we present Cait, an open source…
DEPFET detectors for direct detection of MeV Dark Matter particles
Alexander Baehr, Holger Kluck, Jelena Ninkovic +2
The existence of dark matter is undisputed, while the nature of it is still unknown. Explaining dark matter with the existence of a new unobserved particle is among the most promis…
Towards a Muon Collider
Carlotta Accettura, Dean Adams, Rohit Agarwal +294
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions a…
Determination of alpha_S using hadronic event shape distributions of data taken with the OPAL detector
Jochen Schieck
The measurement of the strong coupling alpha_S using hadronic event shape distributions measured with the OPAL detector at center-of-mass energies between 91 and 209 GeV is summari…
Enhancing European Cooperation in the Search for Dark Matter
Bernard Andrieu, Ties Behnke, Philip Bechtle +47
The search for dark matter is an exciting topic that is pursued in different communities over a wide range of masses and using a variety of experimental approaches. The result is a…
Measurement of the strong coupling alpha_S in e+e- annihilation using the three-jet rate
Jochen Schieck
We present a measurement of the strong coupling alpha_S using data collected with the JADE detector at centre-of-mass energies between 14 and 44 GeV. The three-jet rate as a functi…
Charge carrier generation in RNDR-DEPFET Detectors
Niels Wernicke, Alexander Bähr, Hannah Danhel +6
Depleted p-channel field effect transistor detectors with repetitive-non-destructive readout (RNDR-DEPFETs) achieve a deep sub-electron noise by averaging several independent measu…
Measurement of the Strong Coupling alpha_S from the Four-Jet Rate in e+e- annihilation
