Physical Degrees of Freedom in 2-D String Field Theories | | Norisuke Sakai

20 Jul 1992 | | Journal: | Mod.Phys.Lett. A7 (1992) 3479-3486 | | Subject: | hep-th | | Abstract: | States in the absolute (semi-relative) cohomology but not in the relative cohomology are examined through the component decomposition of the string field theory action for the 2-D string. It is found that they are auxiliary fields without kinetic terms, but are important for instance in the master equation for the Ward-Takahashi identities. The ghost structure is analyzed in the Siegel gauge, but it is noted that the absolute (semi-relative) cohomology states are lost. | | Source: | arXiv, hep-th/9207063 | | Services: | Forum | Review | PDF | Favorites | |
