Abstract
For stringent tests of the Standard Model and the searches for new physics in the decays of B mesons to become possible, an upgrade of today’s highest luminosity colliders, to achieve about 50 times higher luminosity is needed. Extrapolation of current occupancies and radiation damage to this higher luminosity requires more robust vertexing technology than the double layer silicon strip detectors presently used, a detector capable of exquisite spatial resolution whilst withstanding significant low momentum charged particle fluxes and radiation damage. University of Nova Gorica is an active participant in these endeavours through CAP Collaboration, together with Univ. of Hawaii, Univ. of Melbourne, Univ. of Tokyo, National Taiwan University, KEK in Japan and INP from Krakow, Poland. The sensor candidate we propose for the innermost layer of the vertex detector is based upon the monolithic active pixel style architecture (MAPS), that can be fabricated in commercially available processes, either in CMOS or in SOI technology. Initial prototype device development demonstrated that the Continuous Acquisition Pixel sensors (CAP) are capable of meeting physics and operating environment imposed requirements for both the ILC and Super-B experiments. The primary goal of the research is to provide a robust and precise position sensitive detector, that can be used for vertexing purposes in ILC and Super-B experiments, which will give us a deeper understanding of nature. These detectors, although designed specifically for high luminosity particle physics experiments, are superior in resolution and detection efficiency to the technology presently used, and can also be used in medical and other applications, once they are fully developed. Another indirect benefit is the introduction of state-of-the art SOI technology into Slovenia.
Significance for science
At the KEK accelerator facility in Tsukuba, Japan an upgrade of the existing accelerator to a luminosity of 10^36/cm^2/s and the design and construction of a new Belle2 detector, which will be the successor of the existing Belle experiment, has started in 2009. The upgrade efforts are being pursued in a search for signs of New Physics (NP) beyond the Standard Model (SM) of particle physics, which may lead to a paradigm shift in the field and consequentially in all natural sciences.
Apart from this, our research has a direct technological impact. In order to carry out these high precision measurements we need a new detector system which is capable of measuring charged particle tracks with um-resolution and ns-timing and to reconstruct the vertices of rare particle decays in experimental conditions with high radiation background and high track density. Our research is a basis for industrial innovation and application of this technologies to new fields of science, for example medicine through its application in advanced diagnostics tools.
Significance for the country
Direct impact of this project on the economy and the society in Slovenia is twofold. First, it presents direct involvement of Slovenian researchers in an international collaboration, striving to describe and explain fundamental properties of nature – by research activities conducted locally in Nova Gorica. A direct consequence of this collaboration is the introduction of state-of-the art silicon based detector technology and detector characterization techniques to Slovenia, which may inspire local spin-off companies. Second, it presents quality training of physics students of the "School of Applied Sciences" and "Graduate School" of the University of Nova Gorica, who joined the project as an extension to their coursework activities. Work in an international project was a very beneficial experience for their future company-oriented career and for the level of technical knowledge in Slovenia as a whole.
As an indirect impact of the proposed project one should consider the appearance of Slovenia in the global scientific and technological trends - for two consecutive years we have hosted MSc. students from University of Nantes, France in our lab working on the project during the summer months. The success of this and such projects will ensure the recognition of Slovenia as a high technology oriented country, which would further stimulate and promote global economical and financially oriented ties.
