非超对称角上膜的单圈伴随质量

One-loop adjoint masses for branes at non-supersymmetric angles

摘要:

这个过程是基于arXiv:1105.0591 [hep-th],其中我们考虑了交叉D膜配置中的超对称性的破缺,通过角度与它们的超对称值的轻微偏差。我们计算了膜世界体积上伴随标量的辐射修正所产生的质量。在开弦通道中,弦两点函数只接受N~4和N~2超对称位形的红外极限通过信使及其Kaluza-Klein激发的贡献,并在首阶指向快子方向。

英文摘要:

This proceeding is based on arXiv:1105.0591 [hep-th] where we consider breaking of supersymmetry in intersecting D-brane configurations by slight deviation of the angles from their supersymmetric values. We compute the masses generated by radiative corrections for the adjoint scalars on the brane world-volumes. In the open string channel, the string two-point function receives contributions only from the infrared limits of N~4 and N~2 supersymmetric configurations, via messengers and their Kaluza-Klein excitations, and leads at leading order to tachyonic directions.
