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…

Consistency checks of pion-pion scattering data and chiral dispersive calculations

J. R. Pelaez, F. J. Yndurain

We have evaluated forward dispersion relations for scattering amplitudes that follow from direct fits to several sets of pion-pion scattering experiments, together with the precise…

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…

Image states in metal clusters

Patrick Rinke, Kris Delaney, P. Garcia-Gonzalez +1

The existence of image states in small clusters is shown, using a quantum-mechanical many-body approach. We present image state energies and wave functions for spherical jellium cl…

Pressure dependence of the upper critical field of MgB2 and of YNi2B2C

H. Suderow, V. G. Tissen, J. P. Brison +5

We present measurements of H under pressure in MgB and in YNiBC. The changes in the shape of H are interpreted within current models and show the ev…

Quantum Gravity and Lorentz invariance violation in the Standard Model

Jorge Alfaro

The most important problem of fundamental Physics is the quantization of the gravitational field. A main difficulty is the lack of available experimental tests that discriminate am…
