Analysis of Various Polarization Asymmetries In The Inclusive Decay In The Fourth-Generation Standard Model
V. Bashiry, M. Bayar
In this study a systematical analysis of various polarization asymmetries in inclusive $b \rar s \ell^+ \ell^-$ decay in the standard model (SM) with four generation of quarks is c…
Lepton polarization in Decays
V. Bashiry
We study the single and double lepton polarization asymmetries in the semileptonic meson decays , , ), where the strange $…
Double-Lepton Polarization Asymmetries and Polarized Forward Backward Asymmetries in the Rare b \to s \ell^+ \ell^- Decays in a Single Universal Extra Dimension Scenario
V. Bashiry, M. Bayar, K. Azizi
We study the double-lepton polarization asymmetries and single and double-lepton polarization forward backward asymmetries of the rare b \to s \ell^+ \ell^- mode within the Standar…
Exclusive $B \rar ρ\ell^+ \ell^-$ Decay in the Standard Model with Fourth--Generation
K. Zeynali, V. Bashiry
We investigate the influence of the fourth generation of quarks on the branching ratio, the CP-asymmetry and the polarization asymmetries in $B \rar ρ\ell^+ \ell^-$ decay. Taking $…
Exclusive and Decays in the Universal Extra Dimension
V. Bashiry, K. Zeynali
We investigate the influence of the universal extra dimension on the branching ratio in the decay. Taking GeV with one universal ex…
QCD sum rules analysis of the rare $B_c \rar Xν\barν$ decays
K. Azizi, R. Khosravi, V. Bashiry
Taking into account the gluon correction contributions to the correlation function, the form factors relevant to the rare $B_c \rar X ν\barν$ decays are calculated in the framework…
