On the nature of the Lambda(1405) as a superposition of two states
E. Oset, V. K. Magas, Ramos
We use recent data on the reaction with the mass distribution of forming the with a peak at 1420 MeV and a relatively narrow width of $Γ…
Supersymmetry Parameter Analysis: SPA Convention and Project
J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…
Radiative decays and the nature of heavy quarkonia
Xavier Garcia i Tormo, Joan Soto
We argue that the photon spectra in radiative decays of various heavy quarkonium states provide important information on their nature. If two of these states are in the strong coup…
Neural network approach to parton distributions fitting
Andrea Piccione, Joan Rojo
We will show an application of neural networks to extract information on the structure of hadrons. A Monte Carlo over experimental data is performed to correctly reproduce data err…
Fit to the Bjorken, Ellis-Jaffe and Gross-Llewellyn-Smith sum rules in a renormalon based approach
Francisco Campanario, Antonio Pineda
We study the large order behaviour in perturbation theory of the Bjorken, Ellis-Jaffe and Gross-Llewellyn-Smith sum rules. In particular, we consider their first infrared renormalo…
Matching meson resonances to OPE in QCD
A. A. Andrianov, V. A. Andrianov, S. S. Afonin +1
We investigate the possible corrections to the linear Regge trajectories for the light-quark meson sector by matching two-point correlators of quark currents to the Operator Produc…
MW and sin^2θ_eff in Split SUSY: present and future expectations
Jaume Guasch, Siannah Penaranda
We analyse the precision electroweak observables MW and sin^2θ_eff and their correlations in the recently proposed Split SUSY model. We compare the results with the Standard Model…
Production and FCNC decay of supersymmetric Higgs bosons into heavy quarks in the LHC
Santi Bejar, Jaume Guasch, Joan Sola
We analyze the production and subsequent decay of the neutral MSSM Higgs bosons (h = h^0, H^0, A^0) mediated by flavor changing neutral currents (FCNC) in the LHC collider. We have…
Semi-inclusive radiative decays of Upsilon 1S
Xavier Garcia i Tormo, Joan Soto
We discuss in detail the photon spectrum of radiative Upsilon 1S decays taking into account a number of results that have recently appeared in the literature. In particular, we sho…
Evidence for the two pole structure of the Lambda(1405) resonance
V. K. Magas, E. Oset, A. Ramos
The K^- p --> pi^0 pi^0 Sigma^0 reaction is studied within a chiral unitary model. The distribution of pi^0 Sigma^0 states forming the Lambda(1405) shows, in agreement with a recen…
Cross sections for production of closed superstrings at high energy colliders in brane world models
Diego Chialva, Roberto Iengo, Jorge G. Russo
In brane world string models with large extra dimensions, there are processes where fermion and antifermion (or two gluons) can annihilate producing a light particle (e.g. gluon) c…
The effect of the in-medium pentaquark on the kaon optical potential
Laura Tolos, Daniel Cabrera, Angels Ramos +1
The kaon nuclear optical potential is studied including the effect of the pentaquark. The one-nucleon contribution is obtained using an extension of the Jülich meson-exchange…
Structure of Lambda(1405) and chiral dynamics
D. Jido, J. A. Oller, E. Oset +2
We report on a recent theoretical work on the structure of the Lambda(1405) resonance within a chiral unitary approach, in which the resonance is dynamically generated in meson-bar…
Unbiased determination of the proton structure function F_2^p with faithful uncertainty estimation
The NNPDF Collaboration, Luigi Del Debbio, Stefano Forte +3
We construct a parametrization of the deep-inelastic structure function of the proton F_2 based on all available experimental information from charged lepton deep-inelastic scatter…
