Proton-antiproton annihilation at rest into two mesons and the quark line rule
1988
Proton-antiproton annihilation at rest into two mesons is analysed in a model describing annihilation by quark lines. The model allows to fit existing data with two parameters. The parameters describe the amplitudes for diagrams with and without rearrangement of quark lines.
The Mu3e Data Acquisition
2020
The Mu3e experiment aims to find or exclude the lepton flavour violating decay $\mu^+\to e^+e^-e^+$ with a sensitivity of one in 10$^{16}$ muon decays. The first phase of the experiment is currently under construction at the Paul Scherrer Institute (PSI, Switzerland), where beams with up to 10$^8$ muons per second are available. The detector will consist of an ultra-thin pixel tracker made from High-Voltage Monolithic Active Pixel Sensors (HV-MAPS), complemented by scintillating tiles and fibres for precise timing measurements. The experiment produces about 100 Gbit/s of zero-suppressed data which are transported to a filter farm using a network of FPGAs and fast optical links. On the filte…
SU(3) Analysis of $$p\overline p$$ Decays into Two Mesons
1985
The process \(p\overline p \to MM'\) is analyzed in terms of 8 SU(3) invariant amplitudes with definite charge conjugation properties. The amplitudes are constructed such that they either correspond to quark annihilation or rearrangement diagrams. For the C’-odd case the process \(p\overline p \to PS + PS\) is examined, whereas for the C’-even case the decay \(p\overline p \to PS + V\) is analyzed. It will be shown that for C’-odd both annihilation and rearrangement contribute, whereas rearrangement is dominant in the C’-even case.
