Matrix Factorizations, Massey Products and F-Terms for Two-Parameter Calabi-Yau Hypersurfaces
Johanna Knapp, Emanuel Scheidegger
We discuss B-type tensor product branes in mirrors of two-parameter Calabi-Yau hypersurfaces, using the language of matrix factorizations. We determine the open string moduli of th…
Scattering in Mass-Deformed N>=4 Chern-Simons Models
Abhishek Agarwal, Niklas Beisert, Tristan McLoughlin
We investigate the scattering matrix in mass-deformed N>=4 Chern-Simons models including as special cases the BLG and ABJM theories of multiple M2 branes. Curiously the structure o…
Compact extra-dimensions as solution to the strong CP problem
F. L. Bezrukov, Y. Burnier
We show that the strong CP problem can, in principle, be solved dynamically by adding extra-dimensions with compact topology. To this aim we consider a toy model for QCD, which con…
Bulk induced boundary perturbations for N=1 superconformal field theories
Matthias R Gaberdiel, Oliver Schlotterer
The N=1 superconformal circle theory consisting of a free boson and a free fermion is considered. At any radius the theory has standard Dirichlet and Neumann branes, but for ration…
Quantum spinning strings in AdS_4 x CP^3: testing the Bethe Ansatz proposal
Tristan McLoughlin, Radu Roiban, Arkady A. Tseytlin
Recently, an asymptotic Bethe Ansatz that is claimed to describe anomalous dimensions of "long" operators in the planar N=6 supersymmetric three-dimensional Chern-Simons-matter the…
E10 and Gauged Maximal Supergravity
Eric A. Bergshoeff, Olaf Hohm, Axel Kleinschmidt +3
We compare the dynamics of maximal three-dimensional gauged supergravity in appropriate truncations with the equations of motion that follow from a one-dimensional E10/K(E10) coset…
