  1. 71. Data-driven dispersive analysis of the ππ and πK scattering
    Igor Danilkin (Johannes Gutenberg University of Mainz)

    Invited Talk

    We present a data-driven analysis of the resonant S-wave ππ→ππ and πK→πK reactions using the partial-wave dispersion relation. The contributions from the left-hand cuts are accounted for using the Taylor expansion in a suitably constructed conformal variable. The fits are performed to experimental and lattice data as well as Roy analyses. For the ππ scattering we present both a single- and...

  2. 72. On the scalar πK form factor beyond the elastic region

    Invited Talk

    Nowadays, we are experimentally and theoretically pushing the boundaries of our understanding of particle physics to progressively higher energies and precisions. When searching for physics beyond the Standard model, including in CP violating observables, one often encounters observables involving multi-hadron final states, e.g., in semi-leptonic, D- and B-meson decays. In addition, the...

  4. 74. Light-meson spectroscopy at COMPASS
    Boris Grube (Excellence Cluster Universe, Technische Universität München)

    Invited Talk

    The excitation spectrum of light mesons, which are composed of up, down, and strange quarks, is studied since decades. However, it still holds a number of puzzles and surprises that provide new insights into the nature of the strong interaction.

    Recent high-quality data samples from the COMPASS experiment at CERN allow us to not only study the properties of established mesons with...

  6. 76. Thermal effects on open heavy-flavor mesons
    Gloria Montana (University of Barcelona, Institute of Cosmos Sciences (ICCUB))

    Invited Talk

    We have investigated the thermal effects on the properties of open heavy-flavor mesons using a unitarized effective hadronic theory in coupled channels based on chiral and heavy-quark symmetries at finite temperature below Tc within the imaginary-time formalism. The in-medium amplitudes of the scattering of the heavy mesons with the light mesons and the ground-state self-energies and spectral...
