W2-9 Hadronic Physics (DNP/DTP) | Physique hadronique (DPN/DPT)
- Garth Huber (University of Regina)
In this talk, I show how augmenting the pion light-front wavefunction with a dynamical spin component leads to a significant improvement in predicting observables like the mean charge radius, the decay constant, the space-like electromagnetic form factor, the twist-2 pion distribution amplitude and the photon-to-pion transition form factor. Holographic light-front wavefunction for a...
A long-standing goal of hadron physics has been to understand how the quark and gluon degrees of freedom that are present in the fundamental QCD Lagrangian manifest themselves in the spectrum of hadrons. The GlueX Experiment’s place in the global spectroscopy program is complementary to efforts at other facilities: using 8-9 GeV linearly polarized photons at Jefferson Lab, GlueX is focusing...
A central problem of modern physics research is the solution to QCD in the
non-perturbative regime. One method of testing QCD in this low-energy region
is by measuring certain structure constants of hadrons - called
polarizabilities - that show particular promise of allowing a direct
connection to the underlying quark/gluon dynamics through comparison to modern
