Mathematical, Theoretical and Phenomenological Challenges Beyond the Standard Model Perspectives of the Balkan Collaborations

This book contains invited lectures and shorter contributions to the workshop 'Mathematical, Theoretical and Phenomenological Challenges Beyond the Standard Model: Perspectives of the Balkan Collaborations' (BW2003), which was held in Vrnjacka Banja, Serbia, 29 August - 3 September. It was one of the first high-level HEP workshops in the South-East European region after many years, and the papers give a clear perspective on the scientific potential of this area.The contributions cover topics and problems under research in high-energy particle physics and quantum field theory, in particular: string theory and M-theory; grand unification; quantum gravity and cosmology; standard and noncommutative quantum field theory.Some papers concern more mathematical topics, such as the integrability topology of gauge groups and operator matrices.The contributors are leading international scientists, such as G Arutyunov, K Behrndt, G Cardoso, M Chaichian, G Lazarides, D Luest, N Kaloper, G Senjanovic, and J Wess, with an emphasis on researchers from South-East Europe, including B Bajc, A Mikovic and B Sazdovic.The proceedings have been selected for coverage in: - Index to Scientific & Technical Proceedings(R) (ISTP(R) / ISI Proceedings)- Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)- CC Proceedings -- Engineering & Physical Sciences
