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 nonrenormalization of various operators ... 
A perturbative determination of the parameters of an anisotropic quark action
(Elsevier, 2005)The parameters of a 3+1 anisotropic quark action with Symanzikimproved glue are determined at 1loop in perturbation theory. 
Phase shift of isospin2 pi pi scattering from lattice QCD
(2011)Finitevolume lattice QCD calculations offer the possibility of extracting resonance parameters from the energydependent elastic phaseshift computed using the Luscher technique. In this letter, as a trial of the method, ... 
Phase shift with LapH propagators
(2010)The pionpion scattering phase shift is computed using LapH propagators. The LapH method for computing quark propagators is used to form twoparticle correlation functions with a number of different operators. Excited ... 
Physical phase space of lattice YangMills theory and the moduli space of flat connections on a Riemann surface
(Springer Verlag, 1997)It is shown that the physical phase space of deformed Hamiltonian lattice YangMills theory, which was recently proposed in refs.[1,2], coincides as a Poisson manifold with the moduli space of flat connections on a ... 
Polynomial Filtered HMC: An Algorithm for lattice QCD with dynamical quarks
(2012)Polynomial approximations to the inverse of the fermion matrix are u sed to filter the dynamics of the upper energy scales in HMC simulations. The use of a multiple timescale integration sc heme allows the filtered ... 
Positive solutions for nonlinear singular boundary value problems on the half line
(Hikari Ltd, 2007)We discuss the existence of positive solutions for singular second order boundary value problems x'' = ?f(t, x, x'), ax(0) ? bx'(0) = k ? 0, x'(?) = 0, where f may be singular at x = 0 and x' = 0 and can change sign. ... 
Practical alltoall propagators for lattice QCD
(Elsevier, 2005)A new method for computing all elements of the lattice quark propagator is proposed. The method combines the spectral decomposition of the propagator, computing the lowest eigenmodes exactly, with noisy estimators which ... 
A precise determination of B_K in quenched QCD
(2006)The B K parameter is computed in quenched lattice QCD with Wilson twisted mass fermions. Two variants of tmQCD are used; in both of them the relevant S = 2 fourfermion operator is renormalised multi ... 
Precision Spectroscopy of AdS/CFT
(Institute of Physics, 2003)We extend recent remarkable progress in the comparison of the dynamical energy spectrum of rotating closed strings in AdS5 ? S5 and the scaling weights of the corresponding nonnearBPS operators in planar = 4 supersymmetric ... 
Progress in lattice algorithms
(Elsevier, 2002)The development of Monte Carlo algorithms for generating gauge field configurations with dynamical fermions and methods for extracting the most information from ensembles are summarised. 
Progress in leptonic and semileptonic decays in lattice QCD
(American Physical Society, 1999)The status of lattice calculations of heavy quark phenomenology is reviewed. Particular emphasis is placed on the understanding and control of the calculational uncertainties. The ensuing implications for constraining ... 
Pseudodistances invariantes sur les domaines convexes d'un espace localement convexe
(Scuola Normale Superiore, 1985) 
Pulsation and precession of the resonant swinging spring
(Elsevier, 2004)When the frequencies of the elastic and pendular oscillations of an elastic pendulum or swinging spring are in the ratio 2:1, there is a regular exchange of energy between the two modes of oscillation. We refer to this ... 
Puzzles of Î·deformed AdS<inf>5</inf> Ã S5
(2015)We derive the part of the Lagrangian for the sigma model on the η deformed AdS 5 × S 5 space which is quadratic in fermions and has the full dependence on bosons. We then show that there exists a field ... 
QCD Coupling from a Nonperturbative Determination of the ThreeFlavor ?? Parameter
(2017)We present a lattice determination of the Λ parameter in threeflavor QCD and the strong coupling at the Z pole mass. Computing the nonperturbative running of the coupling in the range from 0.2 to 70 GeV, and using ... 
QCD on 2 + 2 anisotropic lattices
(Elsevier, 2003)We discuss the implementation of QCD on 2 + 2 anisotropic lattices. Technical details regarding the choice of the action as well as perturbative and nonperturbative improvement are analyzed. The physical applications ... 
Quadratic action for type IIB supergravity on AdS(5) x S(5)
(Institute of Physics, 1999)The quadratic action for physical fields of type IIB supergravity model on AdS5?S5 is derived starting from the recently found covariant action. All boundary terms that have to be added to the action to be used in the ...
