Contributions to the width difference in the neutral D system from hadronic decays

2015

View full text Add to dashboard Cite

Recent studies of several multi-body D 0 meson decays have revealed that the final states are dominantly CP -even. However, the small value of the width difference between the two physical eigenstates of the D 0 -D 0 system indicates that the total widths of decays to CP -even and CP -odd final states should be the same to within about a percent. The known contributions to the width difference from hadronic D 0 decays are discussed, and it is shown that an apparent excess of quasi-CPeven modes is balanced, within current uncertainty, by interference effects in quasiflavour-specific decays. Decay modes which may significantly affect the picture with improved measurements are considered.ii

“…The strong phase differences are not accessible in these measurements but have to come from measurements performed using quantum-correlated D 0 -D 0 pairs produced at threshold. Such measurements are available from CLEO [86,87,88,89] and BESIII [90]. In addition, further constraints on these strong phase differences can be obtained from the combination of several measurements that share the underlying mixing parameters but are subject to different strong phase differences.…”

This paper gives an overview of charm physics. It is a lecture write-up aimed at students with a minimum of prior knowledge in particle physics, but at the same time provides a state-of-the art review of the field. The main focus is on mixing and CP violation, which is a field with ever growing attention since first evidence for charm mixing was observed in 2007. Other areas covered are charm spectroscopy, production, as well as rare decays. Flavorful Ways to New Physics
