  • Discrete R-symmetries and anomaly universality in heterotic orbifolds 
    Bizet, Nana G. Cabo; Kobayashi, Tatsuo; Peña, Damián K. Mayorga; Parameswaran, Susha L.; Schmitz, Matthias; Zavala, Ivonne (New York : Springer, 2014)
    We study discrete R-symmetries, which appear in the 4D low energy effective field theory derived from heterotic orbifold models. We derive the R-symmetries directly from the geometrical symmetries of the orbifolds. In ...
  • 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 ...
