SO(N) invariant Wess-Zumino action and its quantization
(Springer Verlag, 1996)A consistent quantization procedure of anomalous chiral models is discussed. It is based on a modification of the classical action by adding Wess-Zumino terms. The SO(3) invariant WZ action for the SU(3) model is constructed. ... -
Inversion symmetric 3-monopoles and the Atiyah-Hitchin manifold
(IOP, 1996)We consider 3-monopoles symmetric under inversion symmetry. We show that the moduli space of these monopoles is an Atiyah?Hitchin submanifold of the 3-monopole moduli space. This allows what is known about 2-monopole ... -
Tetrahedral and cubic monopoles
(Springer Science + Business Media, 1996)Using a numerical implementation of the ADHMN construction, we compute the fields and energy densities of a charge three monopole with tetrahedral symmetry and a charge four monopole with octahedral symmetry. We then ... -
Actions of groups of birationally extendible automorphisms
(World Science Publishing, 1996)The origin of this work is found in the study of automorphisms of domains D in Cn, n > 1. For example, suppose for the moment that D is relatively compact and recall that in this case the group Aut(D) of all holomorphic ... -
Elliptic Ruijsenaars-Schneider model from the cotangent bundle over the two-dimensional current group
(American Institute of Physics, 1997)It is shown that the elliptic Ruijsenaars?Schneider model can be obtained from the cotangent bundle over the two-dimensional current group by means of the Hamiltonian reduction procedure. -
Efficient glueball simulations on anisotropic lattices
(American Physical Society, 1997)Monte Carlo results for the low-lying glueball spectrum using an improved, anisotropic action are presented. Ten simulations at lattice spacings ranging from 0.2 to 0.4 fm and two different anisotropies have been performed ... -
Elliptic Ruijsenaars-Schneider model via the Poisson reduction of the Affine Heisenberg Double
(Institute of Physics, 1997)It is shown that the elliptic Ruijsenaars-Schneider model can be obtained from the affine Heisenberg Double by means of the Poisson reduction procedure. The dynamical r-matrix naturally appears in the construction. -
Effect of tree-level and mean-field improvement on the light-hadron spectrum in quenched QCD
(American Physical Society, 1997)We compute the light-hadron mass spectrum at b55.7 using the O(a)-improved Sheikholeslami-Wohlert fermion action with two choices of the clover coefficient: the classical value c51 and a mean-field or tadpole-improved ... -
SU(N) monopoles and Platonic symmetry
(American Institute of Physics, 1997)We discuss the ADHMN construction for SU(N) monopoles and show that a particular simplification arises in studying charge N?1 monopoles with minimal symmetry breaking. Using this we construct families of tetrahedrally ... -
New hyper-Kaehler manifolds by fixing monopoles
(American Physical Society, 1997)The construction of new hyper-Ka?hler manifolds by taking the infinite monopole mass limit of certain Bogomol?nyi-Prasad-Sommerfield monopole moduli spaces is considered. The one-parameter family of hyper- Ka?hler manifolds ... -
Euromath system: alphabets and fonts
(Institute of Computational Technologies, 1997)We describe some of the principles behind the design of the Euromath system, concentrating on some aspects that are needed to explain how the system deals with alphabets and fonts and are not immediately apparent from a ... -
Physical phase space of lattice Yang-Mills 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 Yang-Mills theory, which was recently proposed in refs.[1,2], coincides as a Poisson manifold with the moduli space of flat connections on a ... -
SU(3) glueballs on coarse, anisotropic lattices
(Elsevier, 1997)Results from a calculation of the low-lying glueball spectrum of pure-gauge SU(3) are used as a test of the effectiveness of improved discretisation schemes in reducing finite spacing errors. Glueball masses are extracted from ... -
Antisymmetric tensor field on AdS(5)
(Elsevier, 1998)By using the Hamiltonian version of the AdSrCFT correspondence, we compute the two-point Green function of a local operator in Ds4 Ns4 super Yang-Mills theory, which corresponds to a massive antisymmetric tensor field of ... -
Domains of polyhedral type and boundary extensions of biholomorphisms
(1998)For D, D? analytic polyhedra in Cn, it is proven that a biholomorphic mapping f : D ! D? extends holomorphically to a dense boundary subset under certain condition of general position. This result is also extended to ... -
Four graviton scattering amplitude from S(N) R**8 supersymmetric orbifold sigma model
(Elsevier, 1998)In the IR limit the Matrix string theory is expected to be described by the SNR8 supersymmetric orbifold sigma model. Recently Dijkgraaf, Verlinde and Verlinde proposed a vertex that may describe the type IIA string ... -
Spectroscopy of Bs and Ds mesons
(Elsevier, 1998)We study Bs and Ds spectroscopy in quenched lattice QCD using the Fermilab approach to heavy quarks. We obtain results at four lattice spacings, a, using O(a)-improved Wilson quarks. We compare and contrast the various ... -
Glueball matrix elements on anisotropic lattices
(Elsevier, 1998)We describe a lattice calculation of the matrix elements relevant for glueball production in J/ radiative decays. The techniques for such a calculation on anisotropic lattices with an improved action are outlined. We ... -
Coarse lattice results for glueballs and hybrids
(Elsevier, 1998)A review of new results from lattice simulations of glueballs and heavy-quark hybrid mesons is presented.
