Neutrino Physics: Where Do We Stand, and Where Are We Going? —the Theoretical-phenomenological Perspective *
نویسنده
چکیده
The discoveries and open questions in neutrino physics, as reported at Neutrino 2002 and more recently, are reviewed from a theoretical perspective. During the last several years, stunning experimental results have established that neutrinos almost certainly have nonzero masses and mix. This development opens a whole new world for us to explore. What have we already learned about the neutrinos, and what would we like to find out? Our discussion may be framed in terms of a number of questions: • Do neutrinos truly change from one flavor to another? • How many neutrino species are there? Do sterile neutrinos exist?

متن کاملI-36: Preimplantation Genetic Diagnosis - Where Have We Been and Where Are We Going
Preimplantation genetic diagnosis (PGD) is now considered routine in IVF laboratories with micromanipulation capability and access to genetic diagnostic services. The past two decades have witnessed a dramatic increase in the use of PGD, the number of cycles performed, and the indications for which PGD has been used. This increase has been mirrored by a slow, but steady, increase in the range o...
