Massive Kaluza-Klein Theories and their Spontaneously Broken Symmetries
Olaf Hohm
In this thesis we investigate the effective actions for massive Kaluza-Klein states, focusing on the massive modes of spin-3/2 and spin-2 fields. To this end we determine the spont…
Nonperturbative corrections to 4D string theory effective actions from SL(2,Z) duality and supersymmetry
Daniel Robles-Llana, Martin Rocek, Frank Saueressig +2
We find the D(-1) and D1-brane instanton contributions to the hypermultiplet moduli space of type IIB string compactifications on Calabi-Yau threefolds. These combine with known pe…
The Off-shell Symmetry Algebra of the Light-cone AdS_5 x S^5 Superstring
Gleb Arutyunov, Sergey Frolov, Jan Plefka +1
We analyze the psu(2,2|4) supersymmetry algebra of a superstring propagating in the AdS_5 x S^5 background in the uniform light-cone gauge. We consider the off-shell theory by rela…
AKSZ-BV Formalism and Courant Algebroid-induced Topological Field Theories
Dmitry Roytenberg
We give a detailed exposition of the Alexandrov-Kontsevich-Schwarz- Zaboronsky superfield formalism using the language of graded manifolds. As a main illustarting example, to every…
