Chern-simons invariant
WebConsequently, the gauge-invariant Hamiltonian can be written only in terms of the original phase-space variables. In this situation, the WZ variables are only auxiliary tools that permit to reveal the hidden symmetries present in the original second class model. ... the reduced-SU(2) Skyrme model, the Chern-Simons-Proca quantum mechanics and ... WebIt is well-known that the Chern-Simons action is not gauge invariant. Together with the boundary term (2.5), the total action is still not gauge invariant under the gauge transforma-tion of A!A+ d in general: S tot = Z @M d2x 2A 0@ 1 2vA 1@ 1 + @ 1 (@ 0 v@ 1 ); (2.8) One way to demand the gauge invariance is to restrict the gauge parameter such ...

At the four derivative level, one should also include the Chern-Simons term A∧ Rab∧ Rab, where Rab is the Riemann curvature two-form, together with its supersymmetric completion constructed in [24, 33]. These terms encode the R-current anomaly of a generic dual SCFT, and as such play a crucial ...
