论民主弦场论

On Democratic String Field Theories

Stefano Giaccari, Michael Kroyter

AI总结:

本文重新审视了民主开弦场论,探讨了正则自由理论的可能性,尝试构造最低阶相互作用项并确定规范变换,同时讨论了实现离壳picture changing所需的弦场空间投影。

摘要:

我们重新审视了民主开弦场论,即弦场不受限于单一picture number且picture changing作为规范变换获得的理论。我们描述了正则自由理论的几种可能性,尝试构造最低阶相互作用项,并为其中部分理论确定最低阶规范变换。我们还讨论了可能为一致离壳实现picture changing所需的弦场空间投影。

英文摘要:

We reexamine democratic open string field theories, namely, theories in which string fields are not constrained to a single picture number and picture changing is obtained as a gauge transformation. We describe several possibilities for regular free theories and attempt to construct the lowest order interaction term and identify the lowest order gauge transformation for some of these theories. We also discuss projections over string field spaces that might be needed for a consistent off-shell implementation of picture changing.
