Multiquark-Oriented QCD Sum Rules (2208.13581v1)
Published 29 Aug 2022 in hep-ph, hep-th, and nucl-th
Abstract: We propose to increase the factual reliability of descriptions of exotic multiquark hadrons utilizing the approach to bound states of strongly interacting constituents known as QCD sum rules, by allowing exclusively all contributions that potentially bear some relevance for multiquark states to enter the correlation functions that form the main ingredient of this framework. The route to this goal is illustrated for the (presumably least involved) special case of tetraquark states.
