Spontaneous Breaking of (2+1)-dimensional Lorentz Symmetry by an antisymmetric tensor
Jia-Hui Huang, Guang-Zhou Guo, Hao-Yu Xie +2
One kind of spontaneous (2+1)-dimensional Lorentz symmetry breaking is discussed. The symmetry breaking pattern is . Using the coset construction formal…
Four-Derivative Brane Couplings from String Amplitudes
Katrin Becker, Guangyu Guo, Daniel Robbins
We evaluate the string theory disc amplitude of one Ramond-Ramond field C^(p-3) and two Neveu-Schwarz B-fields in the presence of a single Dp-brane in type II string theory. From t…
Disc amplitudes, picture changing and space-time actions
Katrin Becker, Guangyu Guo, Daniel Robbins
We study in detail the procedure for obtaining couplings of D-branes to closed string fields by evaluating string theory disc amplitudes. We perform a careful construction of the r…
Higher Derivative Brane Couplings from T-Duality
Katrin Becker, Guangyu Guo, Daniel Robbins
The Wess-Zumino coupling on D-branes in string theory is known to receive higher derivative corrections which couple the Ramond-Ramond potential to terms involving the square of th…
Supersymmetry breaking, heterotic strings and fluxes
Katrin Becker, Chris Bertinato, Yu-Chieh Chung +1
In this paper we consider compactifications of heterotic strings in the presence of background flux. The background metric is a T^2 fibration over a K3 base times four-dimensional…
Metastable Flux Configurations and de Sitter Spaces
Katrin Becker, Yu-Chieh Chung, Guangyu Guo
We derive stability conditions for the critical points of the no-scale scalar potential governing the dynamics of the complex structure moduli and the axio-dilaton in compactificat…
