Tensionless Strings from Worldsheet Symmetries [PDF]

open access: yes, 2015
We revisit the construction of the tensionless limit of closed bosonic string theory in the covariant formulation in the light of Galilean conformal symmetry that rises as the residual gauge symmetry on the tensionless worldsheet.

Unconstrained ${\cal N}=2$ higher-spin gauge superfields and their hypermultiplet couplings

open access: yes, 2022
In recent papers arXiv:2109.07639 [hep-th] and arXiv:2202.08196 [hep-th], we constructed free off-shell $\mathcal{N}=2$ supersymmetric higher spin gauge theories in harmonic superspace and their cubic couplings to hypermultiplet.

Effective Field Theories and Inflation [PDF]

open access: yes, 2003
We investigate the possible influence of very-high-energy physics on inflationary predictions focussing on whether effective field theories can allow effects which are parametrically larger than order H^2/M^2, where M is the scale of heavy physics and H ...

Engineering Holographic Superconductor Phase Diagrams [PDF]

open access: yes, 2016
We study how to engineer holographic models with features of a high temperature superconductor phase diagram. We introduce a field in the bulk which provides a tunable "doping" parameter in the boundary theory.

Beyond the Cosmological Standard Model [PDF]

open access: yes, 2014
After a decade and a half of research motivated by the accelerating universe, theory and experiment have a reached a certain level of maturity. The development of theoretical models beyond \Lambda, or smooth dark energy, often called modified gravity ...

Emergence and Correspondence for String Theory Black Holes [PDF]

open access: yes, 2020
This is one of a pair of papers that give a historical-\emph{cum}-philosophical analysis of the endeavour to understand black hole entropy as a statistical mechanical entropy obtained by counting string-theoretic microstates.

Hard Scattering and Gauge/String Duality [PDF]

open access: yes, 2001
We consider high-energy fixed-angle scattering of glueballs in confining gauge theories that have supergravity duals. Although the effective description is in terms of the scattering of strings, we find that the amplitudes are hard (power law). This is a

Morita Duality and Large-N Limits [PDF]

open access: yes, 2001
We study some dynamical aspects of gauge theories on noncommutative tori. We show that Morita duality, combined with the hypothesis of analyticity as a function of the noncommutativity parameter Theta, gives information about singular large-N limits of ...

On a Missed Mechanism of Dielectron Production in Nucleon-Nucleon Collisions

open access: yes, 2010
We examine a new mechanism of $e^+e^-$ pair production in $NN$ collisions associated with the $NN$-decoupled dibaryon $d^\star_1$(1956) formation in the process $NN \to \gamma^\star d^\star_1$, where $\gamma^\star$ is the virtual photon which converts ...

Deconstructing de Sitter [PDF]

open access: yes, 2001
Semiclassical gravity predicts that de Sitter space has a finite entropy. We suggest a picture for Euclidean de Sitter space in string theory, and use the AdS/CFT correspondence to argue that de Sitter entropy can be understood as the number of degrees ...
