Experimental Searches for Light Exotica: Precision and Progress


  • Sean DOBBS

Primary authors


The advent of high intensity hadronic physics experiments has lead to many advances in our understanding of hadronic states, and has raised many questions and new possibilities along the way. One particularly exciting question is how gluonic degrees of freedom contribute to the structure of hadrons. In the meson sector, “hybrid” states with gluonic contributions may have quantum numbers which cannot be formed with a quark-antiquark pair. Identifying such states would be clear evidence of such gluonic contributions, and have been of keen interest for many decades. Recent advances in theoretical predictions of such states, the size and quality of the experimental data available, and the improved theoretical models required to understand these reactions and identify new resonances has reinvigorated the search for hybrid mesons. In this talk, I will describe some of the recent developments in these searches, discuss some of the challenges of analyzing these new data, and illustrate some of the future prospects of studying light quark exotica with hadron and photon beams.
