Glueball Mass Spectrum from Supergravity∗
We review the calculation of the spectrum of glueball masses in non-supersymmetric Yang-Mills theory using the conjectured duality between supergravity and large N gauge theories. The glueball masses are obtained by solving the supergravity wave equations in a black hole geometry. The glueball masses found this way are in unexpected agreement with the available lattice data. We also show how to...

متن کاملGlueball Spectrum for QCD from AdS Supergravity Duality∗
We present the analysis of the complete glueball spectrum for the AdS black hole supergravity dual of QCD4 in strong coupling limit: g N → ∞. The bosonic fields in the supergravity multiplet lead to 6 independent wave equations contributing to glueball states with J = 2, 1, 1−−, 0 and 0. We study the spectral splitting and degeneracy patterns for both QCD4 and QCD3. Despite the expected limitat...
متن کاملGlueball Masses from Supergravity with Flavor
We study the glueballs in a four-dimensional N = 2 super YangMills theory with fundamental matters in terms of the supergravity dual. The supergravity background is constructed by N D3 brane with a probe D7 brane. We numerically compute the glueball masses for 0++ and 1 in the background. We find that the mass ratio of 0++ glueballs is mostly in agreement with the lattice calculations. We compa...
متن کاملA note on the glueball mass spectrum
A conjectured duality between supergravity and N = ∞ gauge theories gives predictions for the glueball masses as eigenvalues for a supergravity wave equations in a black hole geometry, and describes a physics, most close toa hightemeperature expansion of a lattice QCD. We present an analytical solution for eigenvalues and eigenfunctions, with eigenvalues given by zeroes of a certain well-comput...
