Análisis y reconstrucción del decaimiento hadrónico j J/ψ→ K+K−π+π−π0
(2009)
Se determinó la razón de producción para el decaimiento hadrónico J/ψ→ K+K−π+π−π0 y se realizó una comparación con los valores obtenidos en un análisis previo basado en una muestra de 3 millones de eventos de ψ(2S) para ...
Room-temperature synthesis and characterization of highly monodisperse transition metal-doped ZnO nanocrystals
(2006)
Recent experimental verifications of predicted intrinsic room-temperature ferromagnetism in transition metal doped-ZnO nanostructures have increased their attractiveness as promising candidates for optoelectronic and ...

Electric studies of vanadium oxide (V6O13) thin films
(2009)
V6O13 is one of the intermediate phase compounds between the vanadium-oxides VO2 and V2O5. In bulk, this material undergoes a structural transition at approximately 150K, and a magnetic transition from paramagnetic to ...
Spectroscopic studies of Mn/Eu doped phosphates, silicates and borates
(2006)
Lighting consumes about 23% of electric energy nationwide. Any improvement in lighting efficiency will lead to huge benefits for our society. The first generation of light sources was the incandescent lamp with an energy ...
Understanding the atmospheric turbulence structure parameter, Cn2, in the littoral regime
(2006)
Understanding optical propagation through atmospheric turbulence is a highly important step for the efficient implementation of a free space laser communication system and for achieving diffraction limited imaging over ...
16 inch composite material telescope with adaptive optics.key components: wavefront reconstructor & vibration testing
(2006)
Advances in technology has provided means for astronomical optical telescopes to increase the aperture diameter (more light collecting capability) therefore increasing the resolution. Better resolution allows telescopes ...
Testing, installation and development of hardware and software components for the forward pixel detector of CMS
(2007)
The LHC (Large Hadron Collider) will be the particle accelerator with the highest collision energy ever. CMS (Compact Muon Solenoid) is one of the two largest experiments at the LHC. A main goal of CMS is to elucidate the ...
Implementación y validación del ajuste de recorte y de un selector de trazas confiables para la reconstrucción de vertices primarios del experimento CMS
(2008)
The objective of the CMS experiment is to find new particles based on proton- proton collisions. In order to find these new particles it is necessary to determine their interaction point. This is realized using vertex ...
