Prospects for the direct detection of neutralino dark matter in orbifold scenarios
D. G. Cerdeno, T. Kobayashi, C. Munoz
We analyse the phenomenology of orbifold scenarios from the heterotic superstring, and the resulting theoretical predictions for the direct detection of neutralino dark matter. In…
Yukawa Coupling Structure in Intersecting D-brane Models
Noriaki Kitazawa, Tatsuo Kobayashi, Nobuhito Maru +1
The structure of Yukawa coupling matrices is investigated in type IIA T^6/(Z_2 x Z_2) orientifold models with intersecting D-branes. Yukawa coupling matrices are difficult to be re…
4D construction of bulk supersymmetry breaking
Tatsuo Kobayashi, Nobuhito Maru, Koichi Yoshioka
In this letter, we discuss a four-dimensional model with modulus fields which are responsible for supersymmetry breaking. Given non-trivial moduli dependence of the action, the mod…
Restricted flavor structure of soft SUSY breaking trilinear couplings
T. Kobayashi, O. Vives
We analyze the flavor structure of the trilinear couplings in the different theoretical models of SUSY breaking. We generically obtain A_{ij}= A^L_i + A^R_j in all the models exami…
Minimal String Model in , and Orbifold Constructions
H. Kawabe, T. Kobayashi, N. Ohtsubo
We examine whether a minimal string model possessing the same massless spectra as the MSSM can be obtained from , and orbifold constructions. Using an anomaly canc…
