Probing lepton flavour violation in slepton NLSP scenarios
Koichi Hamaguchi, Alejandro Ibarra
In supersymmetric models where the gravitino is the lightest superparticle, the next-to-lightest superparticle (NLSP) is long-lived, and hence could be collected and studied in det…
SUSY-breaking Soft Terms in a MSSM Magnetized D7-brane Model
A. Font, L. E. Ibanez
We compute the SUSY-breaking soft terms in a magnetized D7-brane model with MSSM-like spectrum, under the general assumption of non-vanishing auxiliary fields of the dilaton and Ka…
Cosmological particle-based simulations of galaxy formation; numerical loss of angular momentum and disk heating
Lucio Mayer
We discuss the role that numerical effects have in cosmological N-Body/SPH simulations of disk galaxy formation. We show that the resolution of current state-of-the-art calculation…
Universality Classes of Diagonal Quantum Spin Ladders
M. A. Martin-Delgado, J. Rodriguez-Laguna, G. Sierra
We find the classification of diagonal spin ladders depending on a characteristic integer in terms of ferrimagnetic, gapped and critical phases. We use the finite algorithm D…
A Note on Supersymmetric Godel Black Holes, Strings and Rings of Minimal d=5 Supergravity
Tomas Ortin
We show how any asymptotically flat supersymmetric solution of minimal d=5 supergravity with flat base space can be deformed into another supersymmetric asymptotically-Godel soluti…
Appearance and disappearance signals at a beta-Beam and a Super-Beam facility
A. Donini, E. Fernandez-Martinez, S. Rigolin
In this letter we present the study of the eightfold degeneracy in the measurement including both appearance and disappearance channels. We analyse, for definiteness,…
Analytical model of fast ion behavior in current hole tokamak plasmas
Klaus Schoepf, Victor Yavorskij, Victor Goloborod'Ko +1
A qualitative theoretical approach is proposed for the study of fast ion behavior in tokamak plasmas with a current hole. For the equilibrium magnetic configuration in a current ho…
Orientifolds with Flux
Anamaria Font
We compute the flux induced tadpole and superpotential in various type IIB compact orientifolds in order to study moduli stabilization. We find supersymmetric vacua with $g_s…
Reduction of coupling constants in two-dimensional sigma models
Enrique Álvarez
Two-dimensional sigma models in curved target spaces are considered in which a relationship between the warp factor and the dilaton is imposed in a renormalization group invariant…
Gravitational monopoles, anomalies and M bundles
Juan Jose Manjarin
In this paper we try to clarify the physical meaning of the gauge theory that underlies the K-theoretical classification of RR charges in type IIA. Our main tool are the conditions…
Spin chain sigma models with fermions
Rafael Hernandez, Esperanza Lopez
The complete one-loop planar dilatation operator of N=4 supersymmetric Yang-Mills is isomorphic to the hamiltonian of an integrable PSU(2,2|4) quantum spin chain. We construct the…
Properties of hadron screening masses at small baryonic density
TARO Collaboration, I. Pushkina, Ph. de Forcrand +7
The properties of hadron screening masses around the deconfinement phase transition at finite baryonic density can be studied by evaluating the Taylor coefficients with respect to…
Flux-induced SUSY-breaking soft terms on D7-D3 brane systems
P. G. Camara, L. E. Ibanez, A. M. Uranga
We study the effect of RR and NSNS 3-form fluxes on the effective action of the worldvolume fields of Type IIB D7/D3-brane configurations. The D7-branes wrap 4-cycles on a local Ca…
The Cosmological Origin of Inertia: Mach's Principle
Christoph Schmid
The axes of gyroscopes experimentally define local non-rotating frames, i.e. the time-evolution of axes of inertial frames. But what physical cause governs the time-evolution of gy…
Symmetry Nonrestoration at High Temperature in Little Higgs Models
J. R. Espinosa, M. Losada, A. Riotto
A detailed study of the high temperature dynamics of the scalar sector of Little Higgs scenarios, proposed to stabilize the electroweak scale, shows that the electroweak gauge symm…
Branes on Generalized Calibrated Submanifolds
Juan F. G. Cascales, Angel M. Uranga
We extend previous results on generalized calibrations to describe supersymmetric branes in supergravity backgrounds with diverse fields turned on, and provide several new classes…
Gravitino Dark Matter in the CMSSM and Implications for Leptogenesis and the LHC
Leszek Roszkowski, Roberto Ruiz de Austri, Ki-Young Choi
In the framework of the CMSSM we study the gravitino as the lightest supersymmetric particle and the dominant component of cold dark matter in the Universe. We include both a therm…
Theoretical predictions for the direct detection of neutralino dark matter in the NMSSM
D. G. Cerdeno, C. Hugonie, D. E. Lopez-Fogliani +2
We analyse the direct detection of neutralino dark matter in the framework of the Next-to-Minimal Supersymmetric Standard Model. After performing a detailed analysis of the paramet…
The Fluxed MSSM
Luis E. Ibanez
Recent developemnts in string compactifications in the presence of antisymmetric field backgrounds suggest a new simple and predictive structure for soft terms in the MSSM dependin…
Collective Spin Dynamics in the "Coherence Window" for Quantum Nanomagnets
I. S. Tupitsyn
The spin coherence phenomena and the possibility of their observation in nanomagnetic insulators attract more and more attention in the last several years. Recently it has been sho…
Chiral N=1 4d Orientifolds with D-branes at Angles
Gabriele Honecker
D6-branes intersecting at angles allow for phenomenologically appealing constructions of four dimensional string theory vacua. While it is straightforward to obtain non-supersymmet…

Y. Mambrini, C. Munoz
We carry out a comparison between different kinds of experiments for the detection of neutralino dark matter. In particular, we compare the theoretical predictions for the direct d…
Gamma-ray detection from neutralino annihilation in non--universal SUGRA scenarios
Y. Mambrini, C. Munoz
We analyze the indirect detection of neutralino dark matter in supergravity scenarios with non-universal soft scalar and gaugino masses. In particular, the gamma-ray flux arising f…
