The Task D group research is focused on understanding the spectrum of light quark mesons. In particular, we are searching for the gluonic degrees of freedom in this spectrum. This experimental information is a key ingredient in obtaining a quantitative understanding of the confinement mechanism in QCD. Recent theoretical advances in QCD and in particular Lattice QCD make it possible now to predict the masses of gluonic excitations.
Task D research is supported by the DOE Office of Nuclear Physics and College of Arts & Sciences and the Office of the Vice-President for Research at IU.
Task D also collaborates closely with Prof. Adam Szczepaniak and his students from the Nuclear Theory Center and with Prof. Geoffrey Fox who heads the Community Grids Lab of IU's Pervasive Technology Lab.
The physics of Task D also overlaps strongly with the lattice QCD work headed by Prof. Steve Gottlieb of Task B.
