A novel method for computing torus amplitudes for ZN orbifolds without the unfolding technique

نویسنده

چکیده

A novel method for computing torus amplitudes in orbifold compactifications is suggested. It applies universally for every Abelian ZN orbifold without requiring the unfolding technique. This method follows from the possibility of obtaining integrals over fundamental domains of every Hecke congruence subgroup Γ0[N ] by computing contour integrals over one-dimensional curves uniformly distributed in these domains.

A New Class of Rank Breaking Orbifolds

We describe field-theory T /Zn orbifolds that offer new ways of breaking SU(N) to lower rank subgroups. We introduce a novel way of embedding the point group into the gauge group, beyond the usual mapping of torus and root lattices. For this mechanism to work the torus Wilson lines must carry nontrivial ’t Hooft flux. The rank lowering mechanism proceeds by inner automorphisms but is not relate...

Phenomenological Implications of the Blown-up Orbifolds*+

We discuss the structure of the effective Lagrangian for the (2,2) ZN orbifolds and the corresponding Calabi-Yau manifolds which are obtained by “blowing-up” the orbifold singularities. The method to “blow-up” such singularities is reviewed.’ Results are exact at the string tree-level. In particular the question of generating an intermediate scale MI in such models is addressed. It is shown tha...

N = 2 Strings on Orbifolds

We study closed N = 2 strings on orbifolds of the form T /Z2 and C /Z2. We compute the torus partition function and prove its modular invariance. We analyse the BRST cohomology of the theory, construct the vertex operators, and compute three and four point amplitudes of twisted and untwisted states. We introduce a background of D-branes, and compute twist states correlators.

A Novel Method for Impedance Calculation of Distance Relays Using Third Order Interpolation

All algorithms for impedance calculation use an analog-to-digital converter. The high accuracy of the impedance seen by a distance relay is an important factor in the correct isolation of the faulty part of power systems. To achieve this, a novel technique based on third order interpolation is used in this paper. According to this technique, the times and the values of the obtained samples are...

Soft Computing-based New Interval-valued Pythagorean Triangular Fuzzy Multi-criteria Group Assessment Method without Aggregation: Application to a Transport Projects Appraisal

In this paper, an interval-valued Pythagorean triangular fuzzy number (IVPTFN) as a useful tool to handle decision-making problems with vague quantities is defined. Then, their operational laws are developed. By introducing a novel method of making a decision on the concept of possibility theory, a multi-attribute group decision-making (MAGDM) problem is considered, in which the attribute value...
