A Post Accretionary Origin for Meteoritic and Cometary Organic Solids?
Introduction: The insoluble organic matter (IOM) contained with in all chondritic meteorites constitutes a significant reservoir of extraterrestrial organic matter that in some cases may be as high as 3.5 wt. % [1]. Whereas considerable effort has been made to develop a molecular understanding of meteoritic IOM, there remains considerable uncertainty regarding its origins, i.e., was IOM formed ...
متن کاملThe Origin of the Matter-Antimatter Asymmetry
Although the origin of matter-antimatter asymmetry remains unknown, continuing advances in theory and improved experimental limits have ruled out some scenarios for baryogenesis, for example the sphaleron baryogenesis at the electroweak phase transition in the standard model. At the same time, the success of cosmological inflation and the prospects for discovering supersymmetry at the LHC have ...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولPostinflationary Higgs relaxation and the origin of matter-antimatter asymmetry.
The recent measurement of the Higgs boson mass implies a relatively slow rise of the standard model Higgs potential at large scales, and a possible second minimum at even larger scales. Consequently, the Higgs field may develop a large vacuum expectation value during inflation. The relaxation of the Higgs field from its large postinflationary value to the minimum of the effective potential repr...
متن کاملCometary Volatiles and the Origin of Comets
We describe recent results on the CO/C02/H20 composition of comets and compare these with models of the protoplanetary disk. We argue that the cometary observations require reactions on grain surfaces to convert CO to CO2 and also require formation between the CO and CO2 snow lines. This then requires very early mixing of cometesimals in the protoplanetary disk analogous to the mixing described...
