The Effects of Non-Local Interactions in Rare B Decays, B -> X_s l^+l^-
The effects of non-local interactions in rare B decays, \Bsll, are
investigated. We show the correlation between the branching ratio and the
forward-backward asymmetry via two coefficients of the non-local interactions.
This will certainly help us find any deviations from the standard model through
the non-local interactions.Comment: 16 pages, 5 figures, LaTeX, Accepted for IJMP
General analysis of time evolution of decay spectrum in B^0 -> pi^+ pi^- l^+ l^-
Using the general, model independent form of effective Hamiltonian, the decay
spectrum of B^0 -> pi^+ pi^- l^+ l^- decay is studied. The sensitivity of
experimentally measurable asymmetries to the new Wilson coefficients and time
is studied. It is observed that different asymmetries are sensitive to the new
Wilson coefficients and they can serve as an efficient tool for establishing
new physics beyond SM.Comment: 15 pp, 4 figures (postscript formatted), LaTex formatte
CP Asymmetry of in Low Invariant Mass Region
I analyzed the CP asymmetry of based on model-independent
analysis which includes twelve independent four Fermi operators. The CP
asymmetry is suppressed in the Standard Model, however, if some new physics
make it much larger, the present or the next generation B factories may catch
the CP violation in this decay mode. In this paper, we studied the correlation
of the asymmetry and the branching ratio, and then we will find only a type of
interactions can be enlarge the asymmetry. Therefore, in comparison with
experiments, we have possibility that we can constrain models beyond the
standard model.Comment: 12 pages, 5 figures, LaTeX, Accepted for Physical Review
Lepton polarization and CP-violating effects in "B -> K^* tau^+ tau^-" decay in standard and two Higgs doublet models
The most general model independent expressions for the CP-violating
asymmetry, longitudinal, transversal and normal polarizations of leptons are
derived. Application of these general results to the concrete models such as
Standard model and three different types of two Higgs doublet model is
discussed.Comment: 18 pages, 8 postscripted figure
Longitudinal polarization asymmetry of leptons in the pure leptonic B decays
Longitudinal lepton polarization asymmetry in B_q -> l l (q = d, s$ and l =
e, mu, tau) decays is investigated. The analysis is done in a general manner by
using the effective operators approach. It is shown that the longitudinal
lepton polarization asymmetry would provide a direct search for the scalar and
pseudoscalar type interactions, which are induced in all variants of
Higgs-doublet models.Comment: 7 page
Rare B -> K^* (nu) bar(nu) decay beyond standard model
Using the most general, model-independent form of effective Hamiltonian, the
exclusive, rare B \rar K^\ast \nu \bar \nu decay is analyzed. The sensitivity
of the branching ratios and missing mass-squared spectrum to the new Wilson
coefficients is discussed.Comment: 12 pp, 3 figures (postscript formatted), LaTex formatte
New Physics Effects in Decays
We present a model-independent analysis of rare B decays, . The effect of possible new physics is written in terms of dimension-6
four-fermi interactions. The lepton number violating scalar- and tensor-type
interactions are included, and they induce decays. We show systematically how the branching ratios and
missing mass-squared spectrum depend on the coefficients of the four-fermi
interactions.Comment: 20 pages with 7 figure
T violation in (Lambda_b -> Lambda l^+ l^-) decay beyond standard model
Using the most general, model independent form of effective Hamiltonian, the
transverse polarization P_T of Lambda in Lambda_b -> Lambda l^+ l^- decay is
studied. It is observed that the averaged is very sensitive to the
existence of new physics and can attain large values, which can be measured at
future colliders.Comment: 12 pages, 7 figures, LaTeX formatte
