| Beta-decay total absorption spectroscopy for basic and applied research |
| Speaker: | Prof. Dr. Jose TAIN (Instituto de Fisica Corpuscular, Univ. Valencia and C.S.I.C. Edificio de Institutos de Paterna, Valencia, Spain) |
| Abstract: | An accurate determination of the beta-decay intensity distribution
is important for basic nuclear physics but also in other fields
as astrophysics, reactor technology and neutrino physics.
Total absorption spectroscopy is the only way to obtain accurate
information about the beta intensity distribution for complex decays.
Examples of the information that can be obtained about the
structure of atomic nuclei and of the application of these
data to other fields will be shown. The plans for future work at
existing or planned radioactive beam facilities will be highlighted. |

| Vienna Theory Lunch Club - F-theory: Introduction and recent developments |
| Speaker: | Andres Collinucci (TU Wien) |
| Abstract: | Fourteen years ago, string theory underwent a major paradigm shift when techniques were developed to study the theory non- perturbatively, i.e. in its strongly coupled regime. More specifically, the introduction of D-branes and eventually M-theory opened up windows that relate the different versions of string theory, in different corners of its parameter space. A year after the idea of M-theory was conceived, Vafa developed what can be thought of as its obscure partner, known as "F-theory". Although it is less understood conceptually, F-theory is a more practical tool for model building, i.e. for trying to make contact with the standard model. Curiously, the year 2008 has seen a revival of "F-theory", as new results have emerged in the direction of model building.
In this talk, I will give an overall rough picture of M-theory and F- theory without assuming prior knowledge of string theory. Then, as time permits, I will show an explicit F-theory toy model. Finally, I will summarize the most recent developments in this branch.
