Higher Derivative Extension of 6D Chiral Gauged Supergravity

Understand

Six-dimensional (1,0) supersymmetric gauged Einstein-Maxwell supergravity is extended by the inclusion of a supersymmetric Riemann tensor squared invariant.

• Both the original model as well as the Riemann tensor squared invariant are formulated off-shell and consequently the total action is off-shell invariant without modification of the supersymmetry transformation rules.
• In this formulation, superconformal techniques, in which the dilaton Weyl multiplet plays a crucial role, are used.
• It is found that the gauging of the U(1) R-symmetry in the presence of the higher-order derivative terms does not modify the positive exponential in the dilaton potential.
