Title: Glueball Regge trajectories from gauge-string duality and the pomeron

Abstract

The spectrum of light baryons and mesons has been reproduced recently by Brodsky and Teramond from a holographic dual to QCD inspired in the AdS/CFT correspondence. They associate fluctuations about the AdS geometry with four-dimensional angular momenta of the dual QCD states. We use a similar approach to estimate masses of glueball states with different spins and their excitations. We consider Dirichlet and Neumann boundary conditions and find approximate linear Regge trajectories for these glueballs. In particular the Neumann case is consistent with the Pomeron trajectory.

  • A glueball model that describes excited states of glueballs and other exotic hadrons and which has the form of a closed string that features pointlike masses simulating gluons is considered. Rotational states are studied for this model. Their structure proves to be nontrivial. These states are classified, and their frequency spectrum and physical properties, including the energy and angular momentum, are determined with allowance for spin corrections. The corresponding Regge trajectories characterized by a specific set of slopes are used to describe glueball states.

  • A static string in an AdS Schwarzschild space is dual to a heavy quark-antiquark pair in a gauge theory at high temperature. This space is nonconfining in the sense that the energy is finite for infinite quark-antiquark separation. We introduce an infrared cutoff in this space and calculate the corresponding string energy. We find a deconfining phase transition at a critical temperature T{sub C}. Above T{sub C}, the string tension vanishes representing the deconfined phase. Below T{sub C}, we find a linear confining behavior for large quark-antiquark separation. This simple phenomenological model leads to the appropriate zero temperature limit, correspondingmore » to the Cornell potential and also describes a thermal deconfining phase transition. However, the temperature corrections to the string tension do not recover the expected results for low temperatures.« less
  • We compute the inclusive spectrum of produced particles in e{sup +}e{sup -} annihilation in confining gauge theories that have a gravity dual and show that the momentum distribution exhibits thermal behavior.
