abstract = "In the conventional, or field theoretical, effective theory approach, we have been content with obtaining the spectrum, and constructed low energy Lagrangian guided by symmetry and naturalness. Since we have the first principle of string theory, we can in principle perform more detailed calculations. It turns out that many {"}stringy{"} effects can enhance or suppress the interaction.",

note = "Funding Information: In contrast to the complexity of the Calabi-Yau compactification, the orbifold compactification \[6\] yields a simple model in which one could directly compute quantities of interest. The simplest orbifolds are a slight generalization of tori. One considers the string propagating in a toroidal background, points of which have been identified by some isometrics of the torus. This results in a space with singularities if the isometrics in question have fixed points.
