"Hadron Spectroscopy: Theory and Experiment at the Pi1 Hybrid Meson"
Malte Albrecht
Arkaitz Rodas
Dualing Physicist: Theory and Experiment face off on the matter of Hadron Spectroscopy of the
Pi1 Hybrid Meson. Learn about efforts made in HallD and on the lattice to understand this exotic meson.
Abstract: " Within the hadron spectrum, some particles create an exciting environment to test our
knowledge of QCD, the exotics. These hadrons cannot be described by the simple quark model. Examples
include glueballs, tetra- and pentaquarks, and hybrids. Hybrids are naively characterized at the valence
level as containing a gluon excitation in between the quarks. The pi1(1600) is expected to be the lightest
of these hybrids, decaying to a myriad of final states, producing an elusive state in experimental analyses.
In this talk, we will briefly review the relevance of such state, the challenges that experiment faces when
studying this object, and how a combination of phenomenology, experiment and lattice QCD solved a
long-standing controversy that lasted over two decades."
