  • Erratum: Revisiting coupling selection rules in heterotic orbifold models (Journal of High Energy Physics (2012) 05 (008)) 
    Kobayashi, Tatsuo; Parameswaran, Susha L.; Ramos-Sánchez, Saul; Zavala, Ivonne (Heidelberg : Springer Verlag, 2012)
    Erratum to: Revisiting coupling selection rules in heterotic orbifold models in: Journal of High Energy Physics (2012) 05:8
  • Generalised geometry for string corrections 
    Coimbra, André; Minasian, Ruben; Triendl, Hagen; Waldram, Daniel (Berlin : Springer Verlag, 2014)
    We present a general formalism for incorporating the string corrections in generalised geometry, which necessitates the extension of the generalised tangent bundle. Not only are such extensions obstructed, string symmetries ...
  • Heterotic G(2)-manifold compactifications with fluxes and fermionic condensates 
    Gemmer, Karl-Philip; Lechtenfeld, Olaf (New York, NY : Springer International Publishing, 2013)
    We consider flux compactifications of heterotic string theory in the presence of fermionic condensates on M-1,M-2 x X-7 with both factors carrying a Killing spinor. In other words, M-1,M-2 is either de Sitter, anti-de ...
  • R-charge conservation and more in factorizable and non-factorizable orbifolds 
    Bizet, Nana G. Cabo; Kobayashi, Tatsuo; Pena, Damian K. Mayorga; Parameswaran, Susha L.; Schmitz, Matthias; Zavala, Ivonne (New York, NY : Springer International Publishing, 2013)
    We consider the string theory origin of R-charge conservation laws in heterotic orbifold compactifications, deriving the corresponding string coupling selection rule for factorizable and non-factorizable orbifolds, with ...
  • Revisiting coupling selection rules in heterotic orbifold models 
    Kobayashi, Tatsuo; Parameswaran, Susha L.; Ramos-Sánchez, Saul; Zavala, Ivonne (Heidelberg : Springer Verlag, 2012)
    We study L-point couplings between twisted sector fields in heterotic orbifold compactifications, using conformal field theory. Selection rules provide an easy way to identify which couplings are non-vanishing. Those used ...
