11 Feb 2003 | | Journal: | Phys.Lett. B574 (2003) 98-104 | | Subject: | hep-th | | Affiliation: | Amsterdam Univ.), P. A. Grassi (YITP, Stony Brook) and P. van Nieuwenhuizen (YITP, Stony Brook | | Abstract: | Turning on background fields in string theory sometimes has an alternative interpretation as a deformation of the target space geometry. A particularly well-known case is the NS-NS two form B, which gives rise to space-time non-commutativity. In this note we point out that this phenomenon extends to ten-dimensional superspace when employing a covariant quantization of the superstring, generalizing an observation by Ooguri and Vafa in four dimensions. In particular, we will find that RR field strengths give rise to a non-zero ${ heta, heta}$ anti-commutator, just as in four dimensions, whereas the gravitino yields a non-zero value for $[x, heta]$. | | Source: | arXiv, hep-th/0302078 | | Services: | Forum | Review | PDF | Favorites | |
