Pseudo-Supersymetry and the Domain-Wall/Cosmology Correspondence
نویسندگان
چکیده
The correspondence between domain-wall and cosmological solutions of gravity coupled to scalar fields is explained. Any domain wall solution that admits a Killing spinor is shown to correspond to a cosmology that admits a pseudo-Killing spinor: whereas the Killing spinor obeys a Dirac-type equation with hermitian ‘mass’-matrix, the corresponding pseudo-Killing spinor obeys a Dirac-type equation with a anti-hermitian ‘mass’-matrix. We comment on some implications of (pseudo)supersymmetry. ⋆ To appear in proceedings of IRGAC 2006 1 [email protected] 2 [email protected].

Sgoldstinos: Primaries of Ultra-high Energy Cosmic Rays
In any model with supersymetry being spontaneously broken exists goldstino supermultiplet. In a set of models (pseudo)scalar superpartners of goldstino (sgoldstinos) are light (m < 1 GeV), long-living and sufficiently strongly interacting. There are some puzzles in astrophysics and cosmology without relevant solutions in the framework of the Standard Model. In particular, Ultra High Energy Cosm...
متن کاملDynamic dS / CFT correspondence using the brane cosmology
We explore the dynamic dS/CFT correspondence using the moving domain wall(brane) approach in the brane cosmology. The bulk spacetimes are given by the Schwarzschild-de Sitter (SdS) black hole and the topological-de Sitter (TdS) solutions. We consider the embeddings of (Euclidean) moving domain walls into the (Euclidean) de Sitter spaces. The TdS solution is better to describe the static dS/CFT ...
متن کاملFrom Wave Geometry to Fake Supergravity
The ‘Wave Geometry’ equation of the pre-WWII Hiroshima program is also the key equation of the current ‘fake supergravity’ program. I review the status of (fake) supersymmetric domain walls and (fake) pseudosupersymmetric cosmologies. An extension of the domain-wall/cosmology correspondence to a triple correspondence with instantons shows that ‘pseudosupersymmetry’ has another interpretation as...
متن کاملMATRIX VALUATION PSEUDO RING (MVPR) AND AN EXTENSION THEOREM OF MATRIX VALUATION
Let R be a ring and V be a matrix valuation on R. It is shown that, there exists a correspondence between matrix valuations on R and some special subsets ?(MVPR) of the set of all square matrices over R, analogous to the correspondence between invariant valuation rings and abelian valuation functions on a division ring. Furthermore, based on Malcolmson’s localization, an alternative proof for t...
متن کاملComparison of pseudo-static, Newmark and dynamic response analysis of the final pit wall of Sungun copper mine
Sungun Copper Mine is located in an area with a high level of seismic hazard. Most recently, the Ahar-Varzeqan earthquake with a magnitude of 6.2 on Richter scale occurred on August 11, 2012; at a distance about 40 kilometers away from the mine. Nevertheless, the seismic stability of the final pit wall has not been comprehensively reviewed. In this research, the southwestern wall of the final p...
