Scalar and Pseudoscalar Correlators in Yang-Mills Theory
Scalar Pseudoscalar Correlators Yang-Mills Theory
2010/12/27
Correlation functions of the FF and F\tilde{F} operators in hot SU(3) Yang-Mills theory have recently been studied both on the lattice and in perturbation theory, and the results subsequently compare...
N=4 Supersymmetric Yang-Mills theory in soft-collinear effective theory
N=4 Supersymmetric Yang-Mills theory soft-collinear effective theory
2010/12/27
We formulate N=4 supersymmetric Yang-Mills theory in terms of soft-collinear effective theory. The effective Lagrangian in soft-collinear effective theory is developed according to the power counting ...
D1-brane in Constant R-R 3-form Flux and Nambu Dynamics in String Theory
D1-brane Constant R-R 3-form Flux Nambu Dynamics String Theory
2010/12/23
We consider D1-string in a constant R-R 3-form flux background and analyze its low energy limit. The leading order low energy theory has reparametrization symmetry and is a generalization of an earli...
Ultraviolet singularities in classical brane theory
Ultraviolet singularities classical brane theory
2010/12/23
We construct for the first time an energy-momentum tensor for the electromagnetic field of a p-brane in arbitrary dimensions, entailing finite energy-momentum integrals. The construction relies on di...
Classical GR as a topological theory with linear constraints
Classical GR topological theory
2010/12/27
We investigate a formulation of continuum 4d gravity in terms of a constrained topological (BF) theory, in the spirit of the Plebanski formulation, but involving only linear constraints, of the type ...
General formulation of general-relativistic higher-order gauge-invariant perturbation theory
General formulation perturbation theory
2010/12/27
Gauge-invariant treatments of general-relativistic higher-order perturbations on generic background spacetime is proposed. After reviewing the general framework of the second-order gauge-invariant pe...
We study some features of the confining string connecting a quark-anti-quark pair in Yang-Mills theory. Monte Carlo investigations of the flux tube between two static quarks in the fundamental represe...
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
Galilean symmetry effective theory inflation
2010/12/23
We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
Yangian Superalgebras in Conformal Field Theory
Yangian Superalgebras Conformal Field Theory
2010/12/24
Quantum Yangian symmetry in several sigma models with supergroup or supercoset as target is established. Starting with a two-dimensional conformal field theory that has current symmetry of a Lie supe...
We examine the behavior of the leading Regge trajectory of the open bosonic string in a uniform electromagnetic background and present a consistent set of Fierz-Pauli conditions for these symmetric t...
Brane resolution in heterotic theory through BF term
Brane resolution heterotic theory BF term
2010/12/23
We have studied the resolution of a naked singularity of a conifold in heterotic theory by a BF topological defect living in a 5-brane. The singularity is removed due to Chern-Simons action that chang...
Non-perturbative String Theory from Water Waves
Non-perturbative String Theory Water Waves
2010/12/24
We use a combination of a 't Hooft limit and numerical methods to find non-perturbative solutions of exactly solvable string theories, showing that perturbative solutions in different asymptotic regim...
Forty-five years after the point de d\'epart [1] of density functional theory, its applications in chemistry and the study of electronic structures keep steadily growing. However, the precise form of...
Next-to-leading resummations in cosmological perturbation theory
Next-to-leading resummations cosmological perturbation theory
2010/12/27
One of the nicest results in cosmological perturbation theory is the analytical resummaton of the leading corrections at large momentum, which was obtained by Crocce and Scoccimarro for the propagato...
The Gauge-Bethe Correspondence and Geometric Representation Theory
The Gauge-Bethe Correspondence Geometric Representation Theory
2010/12/24
The Gauge/Bethe correspondence of Nekrasov and Shatashvili relates the spectrum of integrable spin chains to the ground states of supersymmetric gauge theories. Up to now, this correspondence has been...
