Postovane koleginice i kolege,

Pozivam vas da u utorak 19. jula 2011. godine dodjete na seminar koji ce u biblioteci Instituta za fiziku sa pocetkom u 15 casova odrzati Dejan Stojkovic (Department of Physics, SUNY at Buffalo, USA). Naziv seminara je

Vanishing dimensions: theory and phenomenology

Abstract:

Lower-dimensionality at higher energies has manifold theoretical advantages as recently pointed out. Moreover, it appears that experimental evidence may already exists for it - a statistically significant planar alignment of events with energies higher than TeV has been observed in some earlier cosmic ray experiments. If this alignment is not a fluke, then the LHC should be able to see effects associated with the dimensional crossover. Further, (2+1)-dimensional spacetimes have no gravitational degrees of freedom, and gravity waves cannot be produced in that epoch in the early universe. This places a universal maximum frequency at which primordial gravity waves can propagate, which may be accessible to future gravitational wave detectors such as LISA. In this talk, the theoretical motivation for "vanishing dimensions" as well as generic experimental and observational signature will be discussed.



Srdacan pozdrav,
Antun Balaz
