Coupling of the BLG theory to a conformal supergravity background
A bstractThe Bagger-Lambert-Gustavsson theory is coupled to an off-shell D = 3, $ \mathcal{N}=8 $ conformal supergravity background. Local transformation laws of the conformal supergravity multiplet are obtained from those of the D = 4, $ \mathcal{N}=8 $ SO(8) gauged super-gravity. The complete Lagrangian and local transformation laws of the coupled theory are obtained. As an application the supercurrent multiplet in a flat background is obtained.

Comments on higher derivative terms for the tachyon action
We consider the open string tachyon action in a world-sheet sigma model approach. We present explicit calculations up to order 8 in derivatives for the bosonic string, and mimic these to order 6 for the superstring, including terms with multiple derivatives acting on the tachyon field. We reproduce lower derivative terms obtained elsewhere, and speculate on the role of the world-sheet contact terms regularizing the action for the superstring tachyon.

Quasielastic scattering of He6 from C12 at 82.3 MeV/nucleon
Quasielastic scattering of {sup 6}He on a {sup 12}C target was measured at 82.3 MeV/nucleon. Special care was taken to treat the background subtraction at very small angles. The measured differential cross-sections show a large enhancement at small angles relative to the Rutherford cross-section, similar to those observed at lower energies for the scattering of halo nuclei. The overall structure of the cross-section is reasonably reproduced by the optical model calculations. The inelastic channels which populate two low-lying excited states of {sup 12}C target nucleus were included in the framework of the coupled channel analysis. Further systematic theoretical analysis is encouraged.
