Vật lý năng lượng cao, hạt cơ bản, hạt nhân, thiên văn. 1. Flavor Symmetry and Neutrino Mixing Phung Van Dong Institute of Physics, VAST, 10 Dao Tan, Ba Dinh, Ha Noi We give a review of flavor symmetries recently proposed as a leading candidate in solving the tribimaximal neutrino-mixing form. We show how these symmetries work by taking concrete examples: A 4 symmetry in the standard model and 331 model. Báo cáo Mời 2. Some Related Topics in Nuclear Physics and Astrophysics Dao Tien Khoa Viện khoa học và kỹ thuật hạt nhân, 179 Hoàng Quốc Việt, Cầu Giấy, Hà Nội A brief overview on nuclear reactions occuring during the stellar evolution is given, focusing on the neutron star formation after a supernova explosion. We present further results obtained in the self-consistent Hartree-Fock (HF) mean-field approach for the bulk nuclear matter (NM) properties, using different sets of the effective nucleon-nucleon interaction. The HF predictions for the NM binding energy and pressure show that the considered mean-field interactions are divided into two families which are associated with two different behaviors (Asy-soft and Asy-stiff) of the NM symmetry energy at high densities, where only the Asy-stiff type interactions comply with the empirical NM pressure. These two families were shown to predict two different behaviors of the proton-to-neutron ratio in the beta-equilibrium which, in turn, imply two drastically different mechanisms for the neutron star cooling. The detailed DWBA analysis of the charge-exchange (p,n) reaction leading to the isobar analog excitation seems to provide some answer to this open question. Tp. Hồ Chí Minh, 02-06/8/2010 Báo cáo Mời 3. Neutrinos, Scalars and Dark Energy Bruce McKellar Chủ tịch ủy ban Châu Á Liên minh quốc tế các Hội khoa học About 70% of the energy In the Universe is of a form which has negative pressure. The nature of this "dark energy" is unknown, and is the subject of much speculation. I will discuss a model in which neutral fermions, perhaps neutrinos, perhaps super-particles, perhaps other particles, interacting weakly with a light scalar particle, can provide the negative pressure and thus be a candidate for dark energy. Báo cáo Mời 4. Discriminating Supersymmetric Grand Unified Models in Gaugino Mediation Nobuchika Okada (1), Tran Minh Hieu (2, 3) (1) Department of Physics and Astronomy, University of Alabama, Tuscaloosa, AL 35487, USA; (2) Institute of Engineering Physics, Hanoi University of Science and Technology, 1 Dai Co Viet Road, Hanoi, Vietnam; (3) Faculty of Physics, College of Science, Vietnam National University, 334 Nguyen Trai Road, Hanoi, Vietnam It is well-known that SUSY must be broken in a certain way. In order to explain the SUSY breaking mechanism, one introduced the so-called gaugino mediated SUSY breaking (gaugino mediation). However, when the compactification scale is smaller than the GUT scale, the LSP is stau in almost all parameter space. To get the neutralino LSP, the compactification scale should be higher than the GUT scale. We produce mass spectra of gaugino mediation in GUT models consistent with the currently measured value of dark matter relic abundance and Higgs mass bound. Assuming the same LSP mass for both SU(5) and SO(10) GUT models, we find that sizable mass difference appears in left-handed slepton sector, providing a hint to experimentally test which GUT model would be realized in nature.

We investigate the stability of nuclear matter in the Nambu-Jona- Lasinio (NJL) model using the Cornwall-Jackiw-Tomboulis (CJT) effective potential which contributes higher loops. In mean field approximation, it was found that the wanted saturation properties are destroyed in the NJL model which is regarded as an extension of the Walecka mean field model to include negative energy fermion states. The minimum of the thermodynamic potential which corresponds to stable nuclear matter in the Walecka.We consider the saturation of the thermodynamic potential formulated by the CJT potential. Our results show that there exist saturation solutions corresponding to the constrain of the couplings. 28 Báo cáo Miệng 6. Cosmic Formation and Decaying Dark Matter N. Q. Lan (1) and L. C. Tuong (1) Hanoi National University of Education, 136 Xuan Thuy, Cau Giay, Hanoi, Vietnam The cosmological model with bulk viscosity from late-time darkmatter decay can lead to an improved t to the supernova magnituderedshift relation, and argue that it is likely satisfy other constraints as well. When the effects of higher-order terms in the transport equation are included in the form for the bulk viscosity coefficient, it possibly better fits to the cosmological data. Tp.
