A dispersive method to study CP asymmetries in hadronic multi-body decays
L. A. Heuser, A. Reyes-Torrecilla, C. Hanhart +5
We present the details of a dispersive method to construct the amplitudes for hadronic multibody decays based on the universality of pairwise hadronic final-state interactions…
Scattering Theory
Christoph Hanhart, Mikhail Mikhasenko
This chapter provides an overview of the fundamental framework of scattering theory, which is widely used in particle physics to describe and interpret interactions among elementar…
Understanding large localized CP violation in using dispersive methods
L. A. Heuser, A. Reyes-Torrecilla, C. Hanhart +4
We utilize the universality of pion-pion () final-state interactions at small invariant masses to understand the enhanced localized CP violation in ,…
Discovering the in semileptonic decays
M. -L. Du, F. -K. Guo, C. Hanhart +3
The mass and width of the lightest scalar open-charm state listed in the Review of Particle Physics, the , are in puzzling tension with predictions from unitarized…
Single- and double-heavy Hadronic Molecules
C. Hanhart
In this presentation the notion of hadronic molecules is reviewed and it is argued that some of the enigmatic single and double heavy mesons, namely the lowest lying positive parit…
Two-pion exchange for coupled-channel scattering of two heavy mesons
J. T. Chacko, V. Baru, C. Hanhart +1
To improve the theoretical understanding of multiquark states like and , we calculate the heavy-meson heavy-(anti)meson scattering potential up to next-to-…
