We construct, for the first time, an off-shell supersymmetric continuous spin gauge theory in 4-dimensional Minkowski spacetime, both constrained and unconstrained Lagrangian formulations. As extension to on-shell description [1], we employ auxiliary field close algebra of supersymmetry transformations off-shell. The 4d $\mathcal{N}=1$ massless supermultiplet is then denoted by $(\mathrm{\Phi},...

We report on new results in Witten’s cubic string field theory for the off-shell factor in the 4-tachyon amplitude that was not fully obtained explicitly before. This is achieved by completing the derivation of the Veneziano formula in the Moyal star formulation of Witten’s string field theory ~MSFT!. We also demonstrate a detailed agreement of MSFT with a number of on-shell and off-shell compu...

This paper presents a new modelling technique for the deformation of thin anatomical structures like membranes and hollow organs. We show that the behaviour of this type of surface tissue can be abstracted with a modelling of their elastic resistance using shell theory. In order to apply the shell theory in the context of medical simulation, our method propose to base the geometrical reconstruc...
