In this paper, we present the existence of magnetogravitationalfield in the vector model for gravitationalfield and its effects in the Solar system. The results arethe same with ones of Einstein ‘s theory in the firstorder of approximate and agree with experiments.Người trình bày: Võ Văn Ớn19. Tomographic Probability Representation ofQuantum FieldNguyễn Hùng SơnThe tomographic approach to quantum fields isdeveloped. Tomographic symbols of the field operatorsare introduced and their properties are studied. Relationto classical field theory is discussed.Người trình bày: Nguyễn Hùng Sơn20. Fermi Oscillator as a q - Deformed BoseOscillatorLưu Thị Kim Thah, Dương Đại PhươngWe consider a version of q-deformed harmonicoscillators. The matrix representations and theirstatistical distributions have been derived. From theseresults we recover the matrix representations of theFermi operators and Fermi- Dirac statictics as a specialcase of q-boson.Người trình bày: Lưu Thị Kim Thanh21. Specific Solutions In SU(2) Gauge FieldCouples To Massless Scalar FieldNguyễn Văn ThuậnFrom the study of an SU(2) gauge filed coupled to amassless scalar filed, when the spatial component of thegauge field equals zero, we have found solutions for thecorresponding Yang – Mills equations. Nonabelianelectric field of our solutions decreases r3, differ fromclassical electromagnetic formalism. This see that,SU(2) color charge of our solutions at source screened.The energy of the gauge and scalar field confiqurationsof our solutions is less than that of the correspondinggeneralized electromagnetic field configuration whenthe color charge (Công Thức)Người trình bày: Nguyễn Văn Thuận22. Search for High Energy Skimming Neutrinos ata Surface Detector ArrayVõ Văn Thuận, Hoàng Văn KhanhAlong with the charged extremely high energy cosmicrays (EHECRs), the Pierre Auger Observatory (PAO)is able to detect very high energy neutrinos and themost perspective channel is searching by the Cherenkovsurface detector array (SD) for skimming tau-neutrinosat energies from 0.2 to 20 EeV just below the region ofGreisen-Zatsepin-Kuzmin (GZK) cut-off [1]. Thisdetection window is available due to the specific decaysin flight of tau-leptons which produce very inclinedairshowers at low altitudes above the SD array. Anothercombined technique at PAO, the fluorescent detectortelescopes (FD), is much less effective for neutrinoThành phố Đồng Hới (03- 06/8/2009) Trang 31/ 102Thành phố Đồng Hới (03- 06/8/2009) Trang 32/ 102
