Quark Coalescence and Excited Meson States

This paper investigates the formation of mesons, including excited states, from coalescing quark-antiquark pairs. It uses a non-relativistic quark model with a harmonic oscillator potential and Gaussian wave packets. The work is significant because it provides a framework for modeling excited meson states, which are often overlooked in simulations, and offers predictions for unconfirmed states. The phase space approach is particularly relevant for Monte Carlo simulations used in high-energy physics.
