NT/RIKEN Seminar

"D meson mixing via dispersion relation"

Presented by Hsiang-nan Li, National Center for Theoretical Sciences, Physics Division, Taiwan

Friday, June 14, 2019, 2:00 pm — Building 510, CFNS Room 2-38

In this talk I will explain how to calculate the D meson mixing parameters x and y in the Standard Model. Charm physics is notoriously difficult, because most effective theories and perturbation theories do not apply well. I propose to study the D meson mixing via a dispersion relation, which relates low mass dynamics to high mass one. Taking heavy quark results as inputs in the high mass region, we obtain x and y consistent with experimental data at least in order of magnitude.
