Hadron Spectroscopy: Hadron Spectroscopy
- Daniel Carman (JLab)
Recent experimental observations of charged charmonium- and bottomonium-like structures have brought lots of excitements in the field of hadron spectroscopy. If these structures are associated with the existence of the corresponding hadrons, these states includes minimally two quarks and two antiquarks, being objects clearly beyond the conventional quark model picture. Such charged...
In view of the growing need of theoretical tools that can be used in QCD to understand the dynamics of gluons in hadrons, the renormalization group procedure for effective particles (RGPEP) has been applied to several problems in QCD in order to study its utility. The method, based on the Glazek-Wilson similarity renormalization group for Hamiltonians, uses the concept of effective particles,...
The GlueX facility, featuring a linearly polarized 9 GeV real photon beam delivered to a large-acceptance detector system, has recently completed its first phase of running, and analysis efforts of this dataset are well underway. It has been suggested that at GlueX energies, quark systems beyond the three quark and quark-antiquark systems of baryons and mesons, such as hybrid mesons,...
We present a theoretical analysis of $\gamma\gamma^* \to \pi^0\pi^0, \pi^+\pi^-$ and $\gamma\gamma^*\to\pi^0\eta$ processes within the energy range from threshold to 1.4 GeV and the low spacelike virtualities of photons. The Omn`es representation is adopted in order to account for rescattering effects in both s- and d-partial waves, except for $a_2(1320)$, which is approximated as a...
