Encuentro de transferencia tecnológica en detectores sensibles de posición de estado sólido

La red europea AIDA (Advanced European Infrastructures for Detectors at Accelerators), con el apoyo de la red HEPTech, organiza en DESY (Hamburgo) un evento de transferencia tecnológica en detectores sensibles de posición de estado sólido, donde se tratarán sus aplicaciones en otros campos como Medicina, Ingeniería o Ciencias de la Vida. La Oficina de Transferencia Tecnológica (KTO) del Centro Nacional de Física de Partículas, Astropartículas y Nuclear (CPAN) participa en el encuentro, que se desarrolla el 26 y el 27 de marzo de 2012.

 

Los detectores sensibles de posición de estado sólido se utilizan cada vez más en numerosos campos, debido a su versatilidad y otras características ventajosas. En física de partículas se encuentran entre las tecnologías más adecuadas desarrolladas hasta el momento para el seguimiento de las trayectorias de las partículas.

CMS Higgs boson search results from 2010-2011 data samples

CMS Event Display

This week the CMS collaboration will publish the results of its search for the Higgs boson that were presented at CERN in December 2011 [1].

Nine papers will be submitted for publication using the entire data sample of proton-proton collisions collected up to the end of 2011. These data amount to 4.7 fb-1 of integrated luminosity [2]. Eight out of the nine papers discuss the individual analyses of a number of predicted Higgs decay channels. These papers include some improvements in the analyses, most notably in the photon pair decay channel [3].

The ninth paper, submitted today simultaneously with a similar paper by the ATLAS collaboration, presents the combined result of the individual channels [4].

The significance of the largest excess (at 124 GeV) has increased slightly to 2.1 standard deviations [5]. There is no substantive change in our conclusions: the question of the existence of the Standard Model Higgs boson can only be resolved with the collection of more data during 2012.

 

The ATLAS Collaboration submitted the ATLAS Higgs boson search results simultaneously.
