Spectroscopy From The Lattice: The Scalar Glueball

Understand

Lattice calculations allow us to probe the low-lying, non-perturbative spectrum of QCD using first principles numerical methods.

• Here we present the low-lying spectrum in the scalar sector with vacuum quantum numbers including, in fully dynamical QCD for the first time, the mixing between glueball, q-qbar, and meson-meson operators.
