Investigating the light exotic scalar hybrid meson (J<sup>PC</sup> = 0<sup>+-</sup>) using Gaussian QCD sum rules

ORAL

Abstract

We present mass calculations for light (nonstrange and strange) quarkonium hybrid mesons with exotic quantum number JPC = 0+- utilizing a Gaussian QCD sum rule analysis. We consider single narrow, single wide, and double narrow hadronic resonance models, and through a model-independent analysis of the hadronic spectral function, we assess the possibility of distributed resonance strength. Finally, we explore the use of the Hölder inequality as a way to constrain the sum rule methodology.
