On the Complexity of the Circular Chromatic Number
Hamed Hatami, Ruzbeh Tusserkani
Circular chromatic number, is a natural generalization of chromatic number. It is known that it is \NP-hard to determine whether or not an arbitrary graph satisfies $χ(G)…
Seven-branes and Supersymmetry
Eric A. Bergshoeff, Jelle Hartong, Tomas Ortin +1
We re-investigate the construction of half-supersymmetric 7-brane solutions of IIB supergravity. Our method is based on the requirement of having globally well-defined Killing spin…
Finite-size scaling for non-linear rheology of fluids confined in a small space
Michio Otsuki
We perform molecular dynamics simulations in order to examine the rheological transition of fluids confined in a small space. By performing finite-size scaling analysis, we demonst…
Nonextremal black holes are BPS
Christopher M. Miller, Koenraad Schalm, Erick J. Weinberg
Extremal charged black holes are BPS solutions. It is commonly thought that their nonextremal counterparts are not. Further, experience with BPS solutions in flat spacetime suggest…
Holographic Meson Melting
Carlos Hoyos, Karl Landsteiner, Sergio Montero
The plasma phase at high temperatures of a strongly coupled gauge theory can be holographically modelled by an AdS black hole. Matter in the fundamental representation and in the q…
On the underlying E11 symmetry of the D=11 Free Differential Algebra
Silvia Vaula
We study the reduction of the Free Differential Algebra (FDA) of D=11 supergravity to an ordinary algebra. We show that in flat background and with vanishing three-form field stren…
Is violation of Newton's second law possible?
A. Yu. Ignatiev
Astrophysical observations (usually explained by dark matter) suggest that classical mechanics could break down when the acceleration becomes extremely small (the approach known as…
Spinning Strings as Small Black Rings
Atish Dabholkar, Norihiro Iizuka, Ashik Iqubal +2
Certain supersymmetric elementary string states with spin can be viewed as small black rings whose horizon has the topology of S^1 \times S^{d-3} in a d-dimensional string theory.…
SL(2,R)-invariant IIB Brane Actions
Eric A. Bergshoeff, Mees de Roo, Sven F. Kerstan +2
We give a universal SL(2,R)-invariant expression for all IIB p-brane actions with p=-1,1,3,5,7,9. The Wess-Zumino terms in the brane actions are determined by requiring (i) target…
Symmetry breaking from Scherk-Schwarz compactification
M. Salvatori
We analyze the classical stable configurations of an extra-dimensional gauge theory, in which the extra dimensions are compactified on a torus. Depending on the particular choice o…
Towards constraints on the SUSY seesaw from flavour-dependent leptogenesis
S. Antusch, A. M. Teixeira
We systematically investigate constraints on the parameters of the supersymmetric type-I seesaw mechanism from the requirement of successful thermal leptogenesis in the presence of…
On the detectability of the CMSSM light Higgs boson at the Tevatron
Leszek Roszkowski, Roberto Ruiz de Austri, Roberto Trotta
We examine the prospects of detecting the light Higgs h^0 of the Constrained MSSM at the Tevatron. To this end we explore the CMSSM parameter space with μ>0, using a Markov Chain M…
Dynamics of critical vortices on the torus and on the plane
Antonio Gonzalez-Arroyo, Alberto Ramos
We use the Bradlow parameter expansion to construct the metric tensor in the space of solutions of the Bogomolny equations for the Abelian Higgs model on a two-dimensional torus. U…
RG flow of the Polyakov-loop potential: First status report
J. Braun, H. Gies, H. J. Pirner
We study SU(2) Yang-Mills theory at finite temperature in the framework of the functional renormalization group. We concentrate on the effective potential for the Polyakov loop whi…
Crystal Melting and Black Holes
Jonathan J. Heckman, Cumrun Vafa
It has recently been shown that the statistical mechanics of crystal melting maps to A-model topological string amplitudes on non-compact Calabi-Yau spaces. In this note we establi…
Gauge/gravity duality and meta-stable dynamical supersymmetry breaking
Riccardo Argurio, Matteo Bertolini, Sebastian Franco +1
We engineer a class of quiver gauge theories with several interesting features by studying D-branes at a simple Calabi-Yau singularity. At weak 't Hooft coupling we argue using fie…
All the supersymmetric solutions of N=1,d=5 ungauged supergravity
J. Bellorin, P. Meessen, T. Ortin
We classify the supersymmetric solutions of ungauged N=1 d=5 SUGRA coupled to vector multiplets and hypermultiplets. All the solutions can be seen as deformations of solutions with…
Stringy Instantons and Quiver Gauge Theories
Bogdan Florea, Shamit Kachru, John McGreevy +1
We explore contributions to the 4D effective superpotential which arise from Euclidean D3 branes (``instantons'') that intersect space-filling D-branes. These effects can perturb t…
A Crossing-Symmetric Phase for AdS_5 x S^5 Strings
Niklas Beisert, Rafael Hernandez, Esperanza Lopez
We propose an all-order perturbative expression for the dressing phase of the AdS_5 x S^5 string S-matrix at strong coupling. Moreover, we are able to sum up large parts of this ex…
Chiral Expansion from Renormalization Group Flow Equations
L. Jendges, B. Klein, H. -J. Pirner +1
We explore the influence of the current quark mass on observables in the low energy regime of hadronic interactions within a renormalization group analysis of the Nambu-Jona-Lasini…
Classes of confining gauge field configurations
Marc Wagner
We present a numerical method to compute path integrals in effective SU(2) Yang-Mills theories. The basic idea is to approximate the Yang-Mills path integral by summing over all ga…
Thermally-Assisted Current-Driven Domain Wall Motion
R. A. Duine, A. S. Nunez, A. H. MacDonald
Starting from the stochastic Landau-Lifschitz-Gilbert equation, we derive Langevin equations that describe the nonzero-temperature dynamics of a rigid domain wall. We derive an exp…
Determination of the Atmospheric Neutrino Fluxes from Atmospheric Neutrino Data
M. C. Gonzalez-Garcia, M. Maltoni, J. Rojo
The precise knowledge of the atmospheric neutrino fluxes is a key ingredient in the interpretation of the results from any atmospheric neutrino experiment. In the standard atmosphe…
Lepton flavour violation in future linear colliders in the long-lived stau NLSP scenario
Alejandro Ibarra, Sourov Roy
We analyze the prospects of observing lepton flavour violation in future e-e- and e+e- linear colliders in scenarios where the gravitino is the lightest supersymmetric particle, an…
