Glueball Masses in Quantum Chromodynamics
We review the recent glueball mass calculations using an efficient method for solving the Schrödinger equation order by order with a scheme preserving the continuum limit. The reliability of the method is further supported by new accurate results for (1+1)-dimensional σ models and (2+1)-dimensional non-abelian models. We present first and encouraging data for the glueball masses in 3+1 dimensio...
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 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 کاملFROM BLACK HOLES TO GLUEBALLS: The QCD3 Tensor Glueball at Strong Coupling
A strong coupling calculation of glueball masses based on the duality between supergravity and Yang-Mills theory is presented. Earlier work is extended to non-zero spin. Fluctuations in the gravitational metric lead to the 2 state on the leading Pomeron trajectory with a mass relation: m(0) < m(2) < m(1). Contrary to expectation, the mass of our new 0 state (m = 5.4573) associated with the grav...
متن کاملGlueball masses and Pomeron trajectory in nonperturbative QCD approach
Using a nonperturbative method based on asymptotic behaviour of Wilson loops we calculate masses of glueballs and corresponding Regge–trajectories. The method contains no fitting parameters and the mass scale is fixed by the meson Regge slope. Theoretical predictions for lowest glueball states are in a perfect agreement with lattice results. The leading glueball trajectory and its relation to t...
