TL;DR
This paper reviews how lattice gauge theory can be used to study hadronic decays, their impact on hadron masses, and the nature of hadronic states, including exotic pentaquarks.
Contribution
It provides an overview of lattice methods for analyzing hadronic decays and discusses recent studies on the structure of hadrons and pentaquarks.
Findings
Lattice studies can distinguish molecular from quark-antiquark states.
Hadronic decays significantly influence hadron mass calculations.
Exploration of pentaquark states via lattice methods is discussed.
Abstract
Hadronic decays and transitions are a key ingredient of hadronic physics. I discuss how hadronic decays can be explored in lattice gauge theory and review studies undertaken. I also discuss the impact of decays on masses and how lattice studies can explore the nature of a hadronic state: namely whether it is a molecular or quark-antiquark state. A brief discussion of lattice exploration of pentaquark states is presented.
