Glueball Masses from Supergravity with Flavor
نویسنده
چکیده
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 compare the glueball masses with the meson masses. The mass ratio MGB/Mmeson is calculated with 1.4. If the mass MGB is set to 1.6GeV , the meson mass Mmeson is given with 1.1GeV . ∗[email protected]

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 mass spectra for supergravity duals of noncommutative gauge theories
We derive the glueball masses in noncommutative super Yang–Mills theories in four dimensions via the dual supergravity description. The spectrum of glueball masses is discrete due to the noncommutativity and the glueball masses are proportional to the noncommutativity parameter with dimension of length. The mass spectrum in the WKB approximation closely agrees with the mass spectrum in finite t...
متن کاملGlueball Masses for the Deformed Conifold Theory
We obtain the spectrum of glueball masses for the N = 1 non-conformal cascade theory whose supergravity dual was recently constructed by Klebanov and Strassler. The glueball masses are calculated by solving the supergravity equations of motion for the dilaton and the two-form in the deformed conifold background. † e-mail address: [email protected], [email protected]
متن کاملGlueballs and AdS/CFT
I review the calculation of the glueball spectrum in non-supersymmetric Yang-Mills theory (in 3 and 4 dimensions) 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 masses obtained this way are in unexpectedly good agreement with the available lattice data, and a...
متن کاملWilson Loop, Regge Trajectory and Hadron Masses in a Yang-Mills Theory from Semiclassical Strings
We compute the one-loop string corrections to the Wilson loop, glueball Regge trajectory and stringy hadron masses in the Witten model of non supersymmetric, large-N Yang-Mills theory. The classical string configurations corresponding to the above field theory objects are respectively: open straight strings, folded closed spinning strings, and strings orbiting in the internal part of the superg...
