p-膜超代数的可积性

p-brane superalgebras via integrability

D. T. Grasso, I. N. McArthur

摘要:

长期以来,人们已经认识到,具有玻色子生成元和费米子生成元的超代数是超弦理论中p-膜和D-膜作用的基础。这些代数已经通过“自下而上”的方法,包括考虑Noether费用,和“自上而下”的方法,涉及明显的超对称不变Wess-Zumino行动的建设。在本文中,我们给出了这些代数的另一种推导的基础上分配到字段的超对称变换的可积性,以解决相关的上同调问题的建设Wess-Zumino项的p-膜和D-膜行动。

英文摘要:

It has long been appreciated that superalgebras with bosonic and fermionic generators additional to those in the super-Poincare algebra underlie p-brane and D-brane actions in superstring theory. These algebras have been revealed via "bottom up" approaches, involving consideration of Noether charges, and by "top down" approaches, involving the construction of manifestly supersymmetry invariant Wess-Zumino actions. In this paper, we give an alternative derivation of these algebras based on integrability of supersymmetry transformations assigned to fields in order to solve a cohomology problem related to the construction of Wess-Zumino terms for p-brane and D-brane actions.
