The Octonionic Membrane / Duff, M.J. (Texas A-M) ; Evans, Jonathan M. (Cambridge U.) ; Khuri, Ramzi R. (McGill U.) ; Lu, J.X. (Texas A-M) ; Minasian, Ruben (CERN)
We generalize the supermembrane solution of D=11 supergravity by permitting the 4-form $G$ to be either self-dual or anti-self-dual in the eight dimensions transverse to the membrane. The self-dual solution is not asymptotically flat [...]

Integrability vs. Supersymmetry / Evans, Jonathan M. (CERN ; Cambridge U.) ; Madsen, Jens Ole (Annecy, LAPP)
We investigate (1,0)-superconformal Toda theories based on simple Lie algebras and find that the classical integrability properties of the underlying bosonic theories do not survive. For several models based on algebras of low rank, we show explicitly that none of the conserved W-algebra generators can be generalized to the supersymmetric case. [...]

Exact scattering in the SU(n) supersymmetric principal chiral model / Evans, Jonathan M. (CERN ; Cambridge U.) ; Hollowood, Timothy J. (Swansea U.)
The complete spectrum of states in the supersymmetric principal chiral model based on SU(n) is conjectured, and an exact factorizable S-matrix is proposed to describe scattering amongst these states. The SU(n)_L*SU(n)_R symmetry of the lagrangian is manifest in the S-matrix construction. [...]

Auxiliary fields for super Yang-Mills from division algebras / Evans, Jonathan M. (CERN)
Division algebras are used to explain the existence and symmetries of various sets of auxiliary fields for super Yang-Mills in dimensions $d=3,4,6,10$. (Contribution to G\"ursey Memorial Conference I: Strings and Symmetries)

The exact mass-gap of the supersymmetric O(N) sigma model / Evans, Jonathan M. (CERN) ; Hollowood, Timothy J. (CERN)
A formula for the mass-gap of the supersymmetric O($N$) sigma model ($N>4$) in two dimensions is derived: $m/\Lambda_{\overline{\rm MS}}=2~{2\Delta}\sin(\pi\Delta)/(\pi\Delta)$, where $\Delta=1/(N-2)$ and $m$ is the mass of the fundamental vector particle in the theory. This result is obtained by comparing two expressions for the free-energy density in the presence of a coupling to a conserved charge; one expression is computed from the exact S-matrix of Shankar and Witten via the the thermodynamic Bethe ansatz and the other is computed using conventional perturbation theory.

Geometry and dynamics with time-dependent constraints / Evans, Jonathan M. (CERN) ; Tuckey, Philip A. (Munich, Max Planck Inst.)
We describe how geometrical methods can be applied to a system with explicitly time-dependent second-class constraints so as to cast it in Hamiltonian form on its physical phase space. Examples of particular interest are systems which require time-dependent gauge fixing conditions in order to reduce them to their physical degrees of freedom. [...]

Supersymmetry algebras and Lorentz invariance for d = 10 super Yang-Mills / Evans, Jonathan M. (CERN)
We consider ways in which conventional supersymmetry can be embedded in the set of more general fermionic transformations proposed recently [\Ref{B}] as a framework in which to study d=10 super Yang-Mills. Solutions are exhibited which involve closed algebras of various numbers of supersymmetries together with their invariance groups: nine supersymmetries with \GT {\times}\SO (1,1) invariance; eight supersymmetries with \SO (7){\times}\SO (1,1) invariance; four supersymmetries with \SO (3,1){\times}\U (3) invariance.
