Bottomonium above deconfinement in lattice nonrelativistic QCD
(American Physical Society, 2011)We study the temperature dependence of bottomonium for temperatures in the range 0.4Tc<T<2.1Tc, using nonrelativistic dynamics for the bottom quark and full relativistic lattice QCD simulations for Nf=2 light flavors on a ... -
Bottomonium at Non-zero Temperature from Lattice Non-relativistic QCD
(2012)The temperature dependence of bottomonium states at temperatures above and below $T_c$ is presented, using non-relativistic dynamics for the bottom quark and full relativistic lattice QCD simulations for two light flavors ... -
Conformal anomaly of (2,0) tensor multiplet in six dimensions and AdS/CFT correspondence
(Institute of Physics, 2000)We compute the conformal anomaly in the free d = 6 superconformal (2,0) tensor multiplet theory on generic curved background. Up to a trivial covariant totalderivative term, it is given by the sum of the type A part ... -
Four-point functions of lowest weight CPOs in N = 4 SYM(4) in supergravity approximation
(American Physical Society, 2000)We show that the recently found quartic action for the scalars from the massless graviton multiplet of type IIB supergravity compactified on an AdS53S5 background coincides with the relevant part of the action of the gauged ... -
Konishi operator at intermediate coupling.
(2011)TBA equations for two-particle states from the sl(2) sector proposed by Arutyunov, Suzuki and the author are solved numerically for the Konishi operator descendent up to 't Hooft's coupling 2046. The data obtained ... -
On the correspondence between gravity fields and CFT operators
(2000)It is shown that a nonlinear derivative-dependent transformation of gravity fields changes correlation functions in a boundary CFT, and, therefore, corresponds to a change of a basis of operators in the CFT. It is argued ... -
Perturbative and instanton corrections to the OPE of CPOs in N = 4 SYM(4)
(Elsevier, 2001)We study perturbative and instanton corrections to the Operator Product Expansion of the lowest weight Chiral Primary Operators of N = 4 SYM4. We confirm the recently observed non-renormalization of various operators ... -
Phase shift of isospin-2 pi pi scattering from lattice QCD
(2011)Finite-volume lattice QCD calculations offer the possibility of extracting resonance parameters from the energy-dependent elastic phase-shift computed using the Luscher technique. In this letter, as a trial of the method, ... -
Scalar quartic couplings in type IIB supergravity on AdS(5) x S(5)
(2000)All quartic couplings of scalar fields sI that are dual to extended chiral primary operators in N = 4 SYM4 are derived by using the covariant equations of motion for type IIB supergravity on AdS5 ? S5. It is shown that ... -
Scalar Quartic Effective Action on AdS5
(1999)We review the recent results concerning the computation of cubic and quartic couplings of scalar fields in type IIB supergravity on AdS5 ? S5 background that are dual to (extended) chiral primary operators in N = 4 SYM4. ... -
Tachyon condensation and universality of DBI action
(Institute of Physics, 2001)We show that a low-energy action for massless fluctuations around a tachyonic soliton background representing a codimension one D-brane coincides with the Dirac-Born-Infeld action. The scalar modes which describe transverse ...
