چکیده
In this paper, we consider half-integer charged particles predicted by models of orbifold compactification of the E8 ×E8 heterotic string theory. We find that it is possible for half-integer charged particles to exist in our universe, and the location of half-interger charged particles in a galaxy should be in the centers of the galaxy. By qualitative analysis, we find half-interger charged particles may be helpful in explaining the formation of SMBH at the large redshift and solving the

We consider a model based on A4 ⋉ (Ze ×Zμ ×Zτ ) flavor symmetry for TriBimaximal lepton mixing with two scalar A4-triplets whose vacuum expectation values have the same alignment. Neutrino masses are generated through effective dimension five Weinberg operators. Charged leptons mass hierarchies are generated with an additional Froggatt-Nielsen U(1)F flavor symmetry under which right-handed lept...

We study the Fareytail expansion of the topological partition function of N = 4 SU (N) super Yang-Mills theory on K3. We argue that this expansion corresponds to a sum over geometries in asymptotically AdS 3 spacetime, which is holographically dual to a large number of coincident fundamental heterotic strings.

We have studied the null-plane hamiltonian structure of the free Yang-Mills fields and the scalar chromodynamics (SQCD4). Following the Dirac’s procedure for constrained systems we have performed a detailed analysis of the constraint structure of both models and we give the generalized Dirac brackets for the physical variables. In the free Yang-Mills case, using the correspondence principle in ...
