Genetic Paralog Analysis and Simulations
Stanislaw Cebrat, Jan P. Radomski, Dietrich Stauffer
Using Monte Carlo methods, we simulated the effects of bias in generation and elimination of paralogs on the size distribution of paralog groups. It was found that the function des…
Log-periodic behavior of finite size effects in field theories with RG limit cycles
A. LeClair, J. M. Roman, G. Sierra
We compute the finite size effects in the ground state energy, equivalently the effective central charge c_{eff}, based on S-matrix theories recently conjectured to describe a cycl…
Realistic D-Brane Models on Warped Throats: Fluxes, Hierarchies and Moduli Stabilization
J. F. G. Cascales, M. P. Garcia del Moral, F. Quevedo +1
We describe the construction of string theory models with semirealistic spectrum in a sector of (anti) D3-branes located at an orbifold singularity at the bottom of a highly warped…
Time-domain simulation of the full hydrodynamic model
A. Aste, R. Vahldieck
A simple upwind discretization of the highly coupled non-linear differential equations which define the hydrodynamic model for semiconductors is given in full detail. The hydrodyna…
Direct and Indirect Detection of Dark Matter in Heterotic Orbifold Models
Pierre Binetruy, Yann Mambrini, Emmanuel Nezri
We study the neutralino dark matter phenomenology in the context of effective field theories derived from the weakly--coupled heterotic string. We consider in particular direct det…
AdS/CFT, Multitrace Deformations and New Instabilities of Nonlocal String Theories
J. L. F. Barbon, C. Hoyos
We study "multitrace" deformations of large N master fields in models with a mass gap. In particular, we determine the conditions for the multitrace couplings to drive tachyonic in…
Flux-induced SUSY-breaking soft terms
P. G. Camara, L. E. Ibanez, A. M. Uranga
We describe the computation of SUSY-breaking terms on a D3-brane in a quite general type IIB supergravity background. We apply it to study the SUSY-breaking induced on the D3-brane…
Chiral field theories from conifolds
K. Landsteiner, C. I. Lazaroiu, Radu Tatar
We discuss the geometric engineering and large n transition for an N=1 U(n) chiral gauge theory with one adjoint, one conjugate symmetric, one antisymmetric and eight fundamental c…
On Sp(0) factors and orientifolds
K. Landsteiner, C. I. Lazaroiu
We discuss the geometric engineering of SO/Sp gauge theories with symmetric or antisymmetric tensor matter and show that the `mysterious' rank zero gauge group factors observed by…
The MSSM fine tuning problem: a way out
J. A. Casas, J. R. Espinosa, I. Hidalgo
As is well known, electroweak breaking in the MSSM requires substantial fine-tuning, mainly due to the smallness of the tree-level Higgs quartic coupling, lambda_tree. Hence the fi…
NUFACT'03: The Fate of the Clones
A. Donini
We present a Neutrino-Factory-based setup with three detectors of different kind in principle capable to solve the eightfold-degeneracy in the simultaneous measurement of …
A cigar-like Universe
B. de Carlos, J. M. Moreno
We study the localization of gravity on a string-like topological defect within a 6-dimensional space-time. Assuming zero cosmological constant we find complete numerical solutions…

P. Dimopoulos, J. Heitger, C. Pena +2
We present some preliminary results for at , using the twisted mass QCD formalism for the computation of bare matrix elements of the operator. The main advantag…
Dark Matter Detection in the Light of Recent Experimental Results
Carlos Munoz
The existence of dark matter was suggested, using simple gravitational arguments, seventy years ago. Although we are now convinced that most of the mass in the Universe is indeed s…
Calorons and fermion zero-modes
Falk Bruckmann, Margarita Garcia Perez, Daniel Nogradi +1
Calorons in the confined phase for SU(n) gauge theory, having a non-trivial Polyakov loop, "dissolve" in n monopole constituents for large enough instanton scale parameters. We dis…
Chiral field theories, Konishi anomalies and matrix models
K. Landsteiner, C. I. Lazaroiu, Radu Tatar
We study a chiral N=1, U(N) field theory in the context of the Dijkgraaf-Vafa correspondence. Our model contains one adjoint, one conjugate symmetric and one antisymmetric chiral m…
M5-brane geometries, T-duality and fluxes
Juan F. G. Cascales, Angel M. Uranga
We describe a duality relation between configurations of M5-branes in M-theory and type IIB theory on Taub-NUT geometries with NSNS and RR 3-form field strength fluxes. The flux pa…
Infinitely-many absorbing-state nonequilibrium phase transitions
F. van Wijland
We present a general field-theoretic strategy to analyze three connected families of continuous phase transitions which occur in nonequilibrium steady-states. We focus on transitio…
Neutrino Physics in the Seesaw Model
A. Broncano, M. B. Gavela, E. Jenkins
The seesaw model of heavy and light Majorana neutrinos and its low-energy effective theory are studied, when the number of heavy neutrinos is equal to or less than the number of li…
Quenched charmonium spectrum
S. Choe, Ph. de Forcrand, M. Garcia Perez +5
We study charmonium using the standard relativistic formalism in the quenched approximation, on a set of lattices with isotropic lattice spacings ranging from 0.1 to 0.04 fm. We co…
From UV/IR mixing to closed strings
E. Lopez
It was shown in hep-th/0301099 that the leading UV/IR mixing effects in noncommutative gauge theories on D-branes are able to capture information about the closed string spectrum o…
Testing the Majorana nature of neutralinos in supersymmetric theories
J. A. Aguilar-Saavedra, A. M. Teixeira
We discuss selectron pair production in e- e- scattering. These processes can only occur via t-channel neutralino exchange, provided that the neutralinos are Majorana fermions. We…
Breakdown of supersymmetry in homogeneous cosmologies in N=1 supergravity
Ja'nos Maja'r, Gyula Bene
A condition of supersymmetric cosmological solutions of simple (N=1) supergravity is formulated in the classical case. As an application we prove that supersymmetry is spontaneousl…
A numerical study of spectral properties of the area operator in loop quantum gravity
Ga'bor Helesfai, Gyula Bene
The lowest 37000 eigenvalues of the area operator in loop quantum gravity is calculated and studied numerically. We obtain an asymptotical formula for the eigenvalues as a function…
