The minimal supersymmetric grand unified theory

We proposed the minimal supersymmetric grand unified SO(10) model, which is described by the representations 10, 126+126bar, 210 and three generations of 16. We showed that it has only 26 parameters, which is the minimum in all known realistic models, and studied the symmetry breaking.

Two body B decays with isosinglet final states in soft collinear effective theory

The deviation in B0 --) eta' KS channel from sin 2 beta was found to be small in agreement with other theoretical determinations but much smaller then found experimentally. After experimental errors are further reduced this could be a signal of new physics.

Minimal supersymmetric grand unified theory : symmetry breaking and the particle spectrum

A method, which enables to obtain the spectrum of supersymmetric models, has been used in the minimal SO(10) unified theory. We expressed all the masses as functions of the the parameters and Higgs expectation values. We used them for the evaluation of the coupling constants as solutions to renormalization group equations.

Correlated bounds on CP asymmetries in B° [to] [eta]'K[sub]s

Flavor SU(3) was used to constrain the direct and indirect CP asymmetries of B0 --) eta' KS. Correlated bounds on the two CP asymmetries were derived, by using rate measurements of B0 decays into K^+ K^-, pi0 pi0, pi0 eta, pi0 eta', eta eta, eta eta', eta' eta'.

Scalar meson in dynamical and partially quenched two-flavor QCD : lattice results and chiral loops

We performed the first dynamical simulation of light scalar meson a0 using quarks with good chiral properties. We calculated the mass of the lightest bar q q resonance with I=1 to be close to the observed resonance a0(1450).
