Experimental overview of spectroscopy from heavy hadron decays
Ignacio Bediaga, Patricia C Magalh\~aes
TL;DR
This paper reviews experimental methods for spectroscopy in heavy meson decays, focusing on scalar resonances like $f_0(980)$ and using CP violation in three-body decays to study low-mass hadron interactions.
Contribution
It provides a comparative analysis of scalar resonance parameters from different decay processes and explores CP violation as a tool for understanding hadron interactions.
Findings
Scalar resonance parameters vary between decay channels
CP violation observed in charmless three-body decays
Spectroscopy techniques reveal details of low-mass hadron interactions
Abstract
We present and discuss some experimental approaches involving spectroscopy from heavy meson decays going to light mesons. In particular we emphasis the scalar resonance , which have different well determined parameter of mass and width obtained from and D decays. We will also show how the CP violation observed in charmless three body decay can be used as tool to understand hadron hadron interaction at low mass region
