We analyze the number of independent chiral zero modes and the winding numbers at the fixed points on T2/ZN (N=2,3,4,6) orbifolds with magnetic flux. In the case of N=2, we derive the index formula n+−n−=M/2+(−V++V−)/4=M/2−V+/2+1 by using t

Abstract We discuss the modular symmetry and zeros of zero-mode wave functions on two-dimensional torus T 2 and toroidal orbifolds T 2 /ℤ N (N = 2, 3, 4, 6) with a background homogeneous magnetic field. As is well-known, magnetic flux contributes t

Abstract Intersecting D-brane models and their T-dual magnetic compactifications provide an attractive framework for particle physics, allowing for chiral fermions and supersymmetry breaking. Generically, magnetic compactifications have tachyons that

Abstract Intersecting D-brane models and their T-dual magnetic compactifications yield attractive models of particle physics where magnetic flux plays a twofold role, being the source of fermion chirality as well as supersymmetry breaking. A potentia

Abstract We formulate a six dimensional U(1) gauge theory compactified on a (two dimensional) sphere S 2 with flux and localized brane sources. Profiles of the lowest Kaluza-Klein (KK) wavefunctions and their masses are derived analytically. In contr

Abstract In this paper, we explore a new avenue to a natural explanation of the observed tiny neutrino masses with a dynamical realization of the three-generation structure in the neutrino sector. Under the magnetized background based on T 2 /Z 2, ma

Abstract We study the CP-violating phase of the quark sector on T 2 /Z N (N = 2, 3, 4, 6) with non-vanishing magnetic fluxes, where properties of possible origins of the CP violation are investigated minutely. In this system, a non-vanishing value is

We consider magnetized orbifolds, where the supersymmetric mass term for a pair of up- and down-type Higgs (super)fields, called μ-term, is localized at the orbifold fixed points, and study the effects on the zero-mode spectra. The zero-mode degener

We classify the combinations of parameters which lead three generations of quarks and leptons in the framework of magnetized twisted orbifolds on T2/Z2, T2/Z3, T2/Z4 and T2/Z6 with allowing nonzero discretized Wilson line phases and Scherk–Schwarz

We investigate blow-up manifolds of T2/ZN(N=2,3,4,6) orbifolds with magnetic flux. First, we construct the blow-up manifolds and zero-mode wave functions on them more precisely. In particular, through an appropriate singular gauge transformation, win
