The forward-backward asymmetry for charm quarks at the Z
ALEPH collaboration
TL;DR
This paper reports a measurement of the charm quark forward-backward asymmetry at the Z boson resonance using ALEPH detector data from LEP, analyzing millions of hadronic decays to extract asymmetry values.
Contribution
It provides a new measurement of charm quark asymmetry at the Z, utilizing a large dataset and specific charm decay channels for improved accuracy.
Findings
Measured charm forward-backward asymmetry at the Z.
Analyzed 4.1 million hadronic Z decays.
Reconstructed about 36,000 charm decays from Z -> ccbar events.
Abstract
The data set collected with the ALEPH detector from 1991 to 1995 at LEP has been analysed to measure the charm forward-backward asymmetry at the Z. Out of a total of 4.1 million hadronic Z decays, about 36000 high momentum D*+, D+ and D0 decays were reconstructed, of which 80% originate from Z -> ccbar events...
