Hadron-Hadron Interactions from Lattice QCD: Theory meets Experiments
Abstract
We summarize recent developments in the study of hadron-hadron interactions using lattice QCD near the physical pion mass (mπ 146 MeV), based on the HAL QCD method and its connection to experimental data. In particular, we focus on several key interaction channels shown below. Also, we examine the two-pion exchange (TPE) mechanism, which governs the long-range behavior of interactions between flavor-singlet hadrons, as well as between nucleons and flavor-singlet hadrons.
