S wave bottomonium states moving in a quarkgluon plasma from lattice NRQCD
(2013)We extend our study of bottomonium spectral functions in the quarkgluon plasma to nonzero momentum. We use lattice QCD simulations with two flavours of light quark on highly anisotropic lattices and treat the bottom quark ... 
The Smatrix of String Bound States
(2008)We find the Smatrix which describes the scattering of twoparticle bound states of the lightcone string sigma model on AdS5xS5. We realize the Mparticle bound state representation of the centrally extended su(22) algebra ... 
The scalar glueball from a tadpoleimproved action
(Elsevier, 1996)The scalar glueball mass and the string tension are computed in lattice SU(3) gauge theory with the aim of establishing the effectiveness of the improved action approach in removing finitespacing artifacts. 
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. ... 
Scale invariance of the Î·deformed AdS<inf>5</inf>ÃS5 superstring, Tduality and modified type II equations
(2016)We consider the ABF background underlying the η deformed AdS 5 × S 5 sigma model. This back ground fails to satisfy the standard IIB supergravity equations which indicates that the corres ... 
Scaling dimensions from the mirror TBA
(2012)The mirror TBA equations proposed by Arutyunov, Suzuki and the author are solved numerically up to 't Hooft's coupling $\lambda\approx 2340$ for several twoparticle states dual to ${\cal N}=4$ SYM operators from the ... 
Semiclassical quantization of rotating superstring in AdS(5) x S**5
(Institute of Physics, 2002)Motivated by recent proposals in hepth/0202021 and hepth/0204051 we develop semiclassical quantization of superstring in AdS5 ? S5. We start with a classical solution describing string rotating in AdS5 and boosted along ... 
Semileptonic decays B>pi lepton neutrino and D>pi lepton neutrion from lattice QCD
(American Physical Society, 2001)We present a lattice QCD calculation of the form factors and differential decay rates for semileptonic decays of the heavylight mesons B and D to the final state pln . The results are obtained with three methodological ... 
Sheaves on P2 and generalised Appell functions
(2017)A closed expression is given for the generating function of ( virtual) Poincaré polynomials of moduli spaces of semistable sheaves on the p rojective plane P 2 with arbitrary rank r and Chern classes. This ... 
Simplified TBA equations of the AdS_5 x S^5 mirror model
(IOP Publishing, 2009)We use the recently found integral representation for the dressing phase in the kinematic region of the mirror theory to simplify the TBA equations for the AdS5 ? S5 mirror model. The resulting set of equations provides ... 
Skyrmions and monopoles: dihedrallysymmetric 3solitons.
(Met, 2001)The similarity between Skyrmions and BogomolnyPrasadSommerfield (BPS) monopoles has often been remarked. In this talk I will illustrate this similarity by reviewing the rational map ansatz and by discussing the specific ... 
SO(N) invariant WessZumino 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 WessZumino terms. The SO(3) invariant WZ action for the SU(3) model is constructed. ... 
Soft covariant gauges on the lattice
(20081008)We present an exploratory study of a oneparameter family of covariant, nonperturbative lattice gaugefixing conditions that can be implemented through a simple Monte Carlo algorithm. We demonstrate that at the numerical ... 
Some cubic couplings in type IIB supergravity on AdS(5) x S(5) and threepoint functions in SYM(4) at large N
(American Physical Society, 2000)All cubic couplings in type IIB supergravity on AdS53S5 that involve two scalar fields sI that are mixtures of the five form field strength on S5 and the trace of the graviton on S5 are derived by using the covariant equations ... 
Sparse coding of birdsong and receptive field structure in songbirds
(2009)Auditory neurons can be characterized by a spectrotemporal receptive field, the kernel of a linear filter model describing the neuronal response to a stimulus. With a view to better understanding the tuning properties ... 
The sparse decomposition of sound in the time domain using nonnegative quadratic programming.
(2009)Nonnegative matrix deconvolution and sparse decomposition are useful tools for source separation and acoustic object recognition. Here, a new algorithm for calculating a sparse decomposition of sound in the time domain ... 
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 ...
