The goal of this short paper is to find Lagrangian for bosonic string with deformed dispersion relation proposed by J. Magueijo and L. Smolin in 2004. We also show that in the preferred case \(f=g\) this Lagrangian reduces into Nambu-Gotto form of relativistic string without modification of the dispersion relation.

关于具有变形色散关系的弦理论的注释

这篇简短论文的目标是找到由 J. Magueijo 和 L. Smolin 在 2004 年提出的具有变形色散关系的玻色子弦的拉格朗日量。我们还表明，在首选情况下，\(f=g\)这个拉格朗日量减少为 Nambu- Gotto 形式的相对论弦没有修改色散关系。
