Exotic gravity theory in topologically non-trivial spacetimes
P. S. Howe, U. Lindström
An exotic linearised theory of superconformal gravity in superspace has been proposed by C.M. Hull. In this note we discuss the bosonic sector of this model in topolog…
Exotic gravity theory in loop space
P. S. Howe, U. Lindström
An exotic linearised theory of superconformal gravity in D = 6, (4,0) superspace, proposed by C. Hull, is discussed in loop space with focus on its bosonic sector. Pursuing an anal…
Super-Laplacians and their symmetries
P. S. Howe, U. Lindström
A super-Laplacian is a set of differential operators in superspace whose highest-dimensional component is given by the spacetime Laplacian. Symmetries of super-Laplacians are given…
Notes on Super Killing Tensors
P. S. Howe, U. Lindström
The notion of a Killing tensor is generalised to a superspace setting. Conserved quantities associated with these are defined for superparticles and Poisson brackets are used to de…
A note on N=8 counterterms
J. M. Drummond, P. J. Heslop, P. S. Howe
The most difficult counterterms to construct in any supersymmetric theory are those that cannot be written as full superspace integrals of gauge-invariant integrands. In maxi…
D=10 supersymmetric Yang-Mills theory at alpha'^4
P. S. Howe, U. Lindstrom, L. Wulff
The deformation of D=10 SYM is the natural generalisation of the term in the abelian Born-Infeld theory. It is shown that this deformation can be extended to in…
Kappa-symmetry for coincident D-branes
P. S. Howe, U. Lindstrom, L. Wulff
A kappa-symmetric action for coincident D-branes is presented. It is valid in the approximation that the additional fermionic variables, used to incorporate the non-abelian degrees…
Kappa-symmetric non-abelian Born-Infeld actions in three dimensions
J. M. Drummond, P. S. Howe, U. Lindstrom
A superembedding construction of general non-abelian Born-Infeld actions in three dimensions is described. These actions have rigid target space and local worldvolume supersymmetry…
Codimension zero superembeddings
J. M. Drummond, P. S. Howe
Superembeddings which have bosonic codimension zero are studied in 3,4 and 6 dimensions. The worldvolume multiplets of these branes are off-shell vector multiplets in these dimensi…
