29. Exotic Glue: The Gluonic Transversity Structure Function

In 1989 Jaffe and Manohar described a leading-twist, double-helicity-flipping structure function ∆(x, Q2) which is sensitive to gluonic states in any hadron of spin J ≥ 1, notably in nuclei. For nuclei, this quantity gives a measure of exotic glue—the contributions from gluons not associated with individual nucleons in a nucleus—as neither nucleons nor pions (nor any state with spin less than...

30. Search for Exotic Gluonic States in the Nucleus

Although crucial to our understanding of nuclear structure, probes of gluonic components of the nucleus can be elusive, as gluons are accessed only indirectly in deep inelastic scattering. In 1989, Jaffe and Manohar identified a leading-twist double-helicity-flip structure function $\Delta(x,Q^2)$ which is sensitive to exotic gluonic states in the nucleus, and is accessible via an inclusive...

In the past few years, our understanding of the meson internal structure in terms of the 1D distribution amplitudes have scored many progresses. For instance, in the case of the pion, the Dyson-Schwinger equations have allowed to compute within a non-perturbative framework, the pion distribution amplitudes which are significantly different from the asymptotic one. This allows to bring back...
