Lining material tests for the AUGER PROJECT surface detector
We are trying to obtain a suitable material to compose the lining of a water Cerenkov tank for the surface detector. part of a hybrid detector of the Auger Project. Results of tests were compared with DuPont 1073Tyvek TM and obtained a reasonable performance for (PVC+BaSO 4 ) material.

Local detection of entanglement
Abstract.We construct an explicit model where it can be
established if a two mode pure Gaussian system is entangled or not
by acting only on one of the parts that constitute the system.
Measuring the dispersion in momentum and the time evolution of the
dispersion in position of one particle we can tell if entanglement
is present as well as the degree of entanglement of the system.

STOCHASTIC DIFFERENTIAL EQUATIONS FOR THE CONTINUOUS SPONTANEOUS LOCALIZATION MODEL
We extend Vink's method [J. C. Vink, Phys. Rev.A48, 1808 (1993)], developed for an isolated quantum system, to an open quantum system consisting of a free particle interacting with its surrounding through a random potential, which causes the spontaneous localization of its wave function. We then obtain the stochastic differential equations (SDE) underlying its evolution. These SDE help us to observe the effects of the environment upon the movement of the particle.

New values for neutrino masses in the context of a horizontal model.
We study in detail an extended version of the Glashow-Salam-Weinberg model for the electroweak interactions. It has an extra global horizontal symmetry, which allows the appearance of neutrino mass terms. The constraints imposed by the standard cosmological model are used to determine the allowed range of variation of the free parameters of this model. We find that unstable massive neutrinos are permitted in a set of values for their masses between 100 eV and --1 GeV.

Using rapidity gaps to distinguish between Higgs boson production by W and gluon fusion.
The possibility of distinguishing between two Higgs boson production mechanisms, {ital W} fusion and gluon fusion, due to rapidity gap existence is investigated using the Monte Carlo event generator PYTHIA. It is shown that, considering the designed c.m. energy and luminosity for the CERN LHC, it is not possible to distinguish between the two Higgs boson production processes as, for a given integrated luminosity, they lead to the same number of events containing a rapidity gap. {copyright} {ital 1996 The American Physical Society.}

ATLAS silicon module assembly and qualification tests at IFIC Valencia
ATLAS experiment, designed to probe the interactions of particles emerging out of proton proton collisions at energies of up to 14 TeV, will assume operation at the Large Hadron Collider (LHC) at CERN in 2007. This paper discusses the assembly and the quality control tests of forward detector modules for the ATLAS silicon microstrip detector assembled at the Instituto de F?sica Corpuscular (IFIC) in Valencia. The construction and testing procedures are outlined and the laboratory equipment is briefly described. Emphasis is given on the module quality achieved in terms of mechanical and electrical stability.

Laser tests of silicon detectors
This paper collects experiences from the development of a silicon sensor laser testing setup and from tests of silicon strip modules (ATLAS End-cap SCT), pixel modules (DEPFET) and large-area diodes using semiconductor lasers. Lasers of 1060 and 680 nm wavelengths were used. A sophisticated method of focusing the laser was developed. Timing and interstrip properties of modules were measured. Analysis of optical effects involved and detailed discussion about the usability of laser testing for particle detectors are presented.
