Heavy-Quark QCD Exotica
Richard F. Lebed, Ryan E. Mitchell, Eric S. Swanson
This review presents an overview of the remarkable progress in the field of heavy-quark exotic hadrons over the past 15 years. It seeks to be pedagogical rather than exhaustive, su…
QCD Compositeness as Revealed in Exclusive Vector Boson Reactions through Double-Photon Annihilation: and
Stanley J. Brodsky, Richard F. Lebed, Valery E. Lyubovitskij
We study the exclusive double-photon annihilation processes, and where the is a neutral vector me…
Exotic Discoveries in Familiar Places: Theory of the Onia and Exotics
Richard F. Lebed
This brief overview presents an introduction to the heavy-quark exotic hadron candidates, , , , , believed to be tetraquark and pentaquark states. After an abridged a…
How Often Do Diquarks Form? A Very Simple Model
Richard F. Lebed
Starting from a textbook result, the nearest-neighbor distribution of particles in an ideal gas, we develop estimates for the probability with which quarks in a mixed , $\ba…
High Resolution Nonperturbative Light-Front Simulations of the True Muonium Atom
Henry Lamm, Richard Lebed
Through the development of a parallel code called TMSWIFT, an extensive light-front quantization study of the nonperturbative spectrum of the bound state , true muonium,…
As the Lightest State
Richard F. Lebed, Antonio D. Polosa
The state has recently been demoted by the Particle Data Group from its previous status as the conventional state, largely d…
