Contribution
It introduces a lattice approach to analyze heavy meson interactions with two static heavy quarks and finite mass light quarks, exploring tetraquark candidates.
Findings
Identification of interaction patterns for different quantum numbers
Insights into the stability of tetraquark configurations
Potential evidence supporting tetraquark existence
Abstract
We report on a lattice investigation of heavy meson interactions and of tetraquark candidates with two very heavy quarks. These two quarks are treated in the static limit, while the other two are up, down, strange or charm quarks of finite mass. Various isospin, spin and parity quantum numbers are considered.
