Evidence for quark-diquark structure of baryons from fluctuations of conserved charges
Michał Marczenko, Krzysztof Redlich
We study fluctuations and correlations of conserved charges in QCD using a string-based description of the hadronic mass spectrum. Mesons and baryons are modeled as open relativist…
