Bojan Nikolić, Danijel Obrić

AI总结:

本文在纯旋量II型超弦理论中研究双空间形式下的T对偶化,通过双坐标置换推导坐标依赖RR场的背景场变换,并证明其与Buscher程序等价。

摘要:

在本文中,我们在纯旋量表述的II型超弦理论中,考察双空间形式体系下的T对偶化。我们所考虑的背景场全部为常数,只有Ramond-Ramond(RR)场以无穷小方式仅依赖于玻色坐标$x^μ$。在双空间中,T对偶变换表示为初始坐标$x^μ$与对偶坐标$y_μ$之间的置换。将这两组坐标组合为双坐标$Z^M=(x^μ,y_μ)$,同时要求T对偶双坐标具有相同的变换规律,我们得到背景场在T对偶下如何变换。将这些结果与通过Buscher T对偶化程序所得结果进行比较,我们可以得出结论:在背景场具有坐标依赖的情形下,这两种方法是等价的。

英文摘要:

In this article we examine T-dualization in double space formalism of type II superstring theory in pure spinor formulation. Background fields that we consider will all be constant except Ramond-Ramond field which will infinitesimally depend only on bosonic coordinates $x^μ$. In double space T-dual transformations are represented as permutations between starting $x^μ$ and dual coordinates $y_μ$. Combining these two sets of coordinates into double coordinate $Z^M = (x^μ, y_μ)$ while demanding that T-dual double coordinates have same transformation laws, we obtain how background fields transform under T-duality. Comparing these results with ones obtained with Buscher T-dualization procedure we are able to conclude that these two approaches are equivalent for cases where background fields have coordinate dependence.
