The large N limit of superconformal field theories and supergravity
, 1998
"... We show that the large N limit of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravity on the product of AntideSitter spacetimes, spheres and other compact manifolds. This is shown by taking some branes in the full M/string theory and ..."

Gravity coupled with matter and the foundation of non commutative geometry
, 1996
"... We first exhibit in the commutative case the simple algebraic relations between the algebra of functions on a manifold and its infinitesimal length element ds. Its unitary representations correspond to Riemannian metrics and Spin structure while ds is the Dirac propagator ds = ×— × = D −1 where D i ..."

work with Ali Chamseddine) to give the SM Lagrangian coupled to gravity. The internal fluctuations of the non commutative geometry are trivial in the commutative case but yield the full bosonic sector of SM with all correct quantum numbers in the slightly non commutative case. The group of local gauge
Oneloop spectroscopy of semiclassically quantized strings: bosonic sector
"... We make a further step in the analytically exact quantization of spinning string states in semiclassical approximation, by evaluating the exact oneloop partition function for a class of twospin string solutions for which quadratic fluctuations form a nontrivial system of coupled modes. This is th ..."

. This is the case of a folded string in the SU(2) sector, in the limit described by a quantum LandauLifshitz model. The same applies to the full bosonic sector of fluctuations over the folded spinning string in AdS5 with an angular momentum J in S5. Fluctuations are governed by a special class of fourth
The Anatomy of Electro–Weak Symmetry Breaking, III: The Higgs sector
 in models beyond the SM and MSSM benchmarks, in preparation
"... The second part of this review is devoted to the Higgs sector of the Minimal Supersymmetric Standard Model. The properties of the neutral and charged Higgs bosons of the extended Higgs sector are summarized and their decay modes and production mechanisms at hadron colliders and at future lepton coll ..."

Do Networks Really Work? A Framework for Evaluating PublicSector Organizational Networks.
 Public Administration Review,
, 2001
"... Although cooperative, interorganizational networks have become a common mechanism for delivery of public services, evaluating their effectiveness is extremely complex and has generally been neglected. To help resolve this problem, we discuss the evaluation of networks of communitybased, mostly pub ..."

A Macroeconomic Model with a Financial Sector," 41
 Journal of Monetary Economics
, 2009
"... This paper studies the full equilibrium dynamics of an economy with financial frictions. Due to highly nonlinear amplification effects, the economy is prone to instability and occasionally enters volatile episodes. Risk is endogenous and asset price correlations are high in down turns. In an enviro ..."

Gaugeinvariant Green’s functions for the bosonic sector of the Standard Model
, 1999
"... There are many applications in gauge theories where the usually employed framework involving gaugedependent Green’s functions leads to considerable problems, for instance the analysis of charged particles or of finite width effects. In order to overcome the difficulties invariably tied to gaugedep ..."

matrix elements as those obtained in the usual framework. We evaluate the full generating functional for the bosonic sector of the Standard Model up to the oneloop level and carry out its renormalization in the onshell scheme. Explicit results for some twopoint functions are given. Gauge invariance is manifest
TwoDimensional Instantons with Bosonization and Physics of
, 1996
"... We evaluate partition functions ZI in topologically nontrivial (instanton) gauge sectors in the bosonized version of the Schwinger model and in a gauged WZNW model corresponding to QCD2 with adjoint fermions. We show that the bosonized model is equivalent to the fermion model only if a particular fo ..."

Implications of Supersymmetry Phases for Higgs Boson Signals and Limits
, 2000
"... We study the supersymmetry parameter region excluded if no Higgs is found at LEP, and the region allowed if a Higgs boson is found at LEP. We describe the full seven parameter structure of the Higgs sector. When supersymmetry phases are included, tan β> ∼ 2 is always allowed, and the lower limit ..."
