On the 0++ Glueball Mass
Stuart Samuel
Abstract
An approximate vacuum wave functional Ψ0 is proposed for 2+1-dimensional Yang-Mills theories. Using Ψ0, one can compute the 0++ glueball mass MG in terms of the string tension. By using the idea of dimensional reduction, a prediction for MG can be made in 3+1 dimensions. One finds MG ≈ 1.5 GeV.
