Gauss Bonnet contact interaction

568 views

Can anyone please point me to a paper in which the tree level contact interaction has been worked out for the Gauss Bonnet Lagrangian, in D > = 5?

Another question I have is that what even without computing the contact term , can we tell some underlying features of it, based on the fact that in 3+1 d, the term is topological in nature?
