摘要

我们重新审视了半经典弦，特别关注了刚性旋转弦，在两个正交ns5膜(i膜)叠的近视界几何中使用弦sigma模型。在NS-NS双形式支持下，我们确定了在得到的t × $$ {S}_{\theta_1}^3 $$ S θ 1 3 × $$ {S}_{\theta_2}^3 $$ S θ 2 3背景下运动的探针弦的守恒电荷，并找到了不同积分常数值下的正则色散关系。使用在两个球体上同时运动的构型，我们得到了一组特定参数的类似巨磁振子的色散关系，而另一组一致的值给了我们一个类似于单尖峰的色散关系。

On spinning strings in I-brane background

A bstract We revisit semiclassical strings, in particular we focus on rigidly rotating strings, in the near horizon geometry of two orthogonal stacks of NS5-branes (I-branes) using the string sigma model. We determine the conserved charges for the probe string moving in the resulting ℝ t × $$ {S}_{\theta_1}^3 $$ S θ 1 3 × $$ {S}_{\theta_2}^3 $$ S θ 2 3 background supported by NS-NS two-forms and find a regularized dispersion relation for different values of integration constants. Using configurations that move simultaneously on both spheres, we obtain the giant magnon like dispersion relation for one particular set of parameters, while other consistent set of values gives us a dispersion relation reminiscent of the single spike.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
