	1. Supersymmetric QCD and CP-violation effects in bar{t}tZ^0 production at the LHC

	Abstract:We investigate the NLO QCD and the CP-violation effects in t\bar{t}Z^0 production at the Large Hadron Collider(LHC) in the minimal supersymmetric standard model(MSSM). Our calculation shows that the total NLO QCD correction in the framework of the CP-conserving MSSM significantly improves the scale uncertainty at the leading order, and the contribution from the pure supersymmetric QCD (pSQCD) correction can exceed $-8%$ with the restrictions of $90~GeV < p_T^t < 120~GeV$ and $120~GeV < p_T^Z < 150~GeV$, where $p_T^t$ and $p_T^Z$ are the transverse momenta of the top-quark and $Z^0$ gauge boson, respectively. Our numerical results demonstrate that the pure supersymmetric QCD correction generally suppresses the total SM-like QCD correction in the CP-conserving MSSM, and tends to be a constant when either $ ilde{t}_1$ or $ ilde{g}$ is heavy enough. We find also that the CP-odd asymmetry ${cal A}_{Phi}$ can reach $2.17 imes 10^{-3}$, if the CP-phase angle really exists in the coupling of gluino-stop-top.

	2. Next-to-leading order QCD predictions for the hadronic WH+jet production

	Abstract:We calculate the next-to-leading order(NLO) QCD corrections to the WH^0 production in association with a jet at hadron colliders. We study the impacts of the complete NLO QCD radiative corrections to the integrated cross sections, the scale dependence of the cross sections, and the differential cross sections ( dσ/dcos θ , dσ/dpT ) of the final W-, Higgs boson and jet. We find that the corrections significantly modify the physical observables, and reduce the scale uncertainty of the leading-order cross section. Our results show that by applying the inclusive scheme with p_{cut}^{T,j} = 20 GeV and taking m_H = 120 GeV , μ= μ_0 = 1/2 (mW + mH), the K-factor is 1.15 for the process ar{p}p o W^±H^0j + X at the Tevatron, while the K-factors for the processes pp o W^?H^0j+X and pp o W^+H^0j+X at the LHC are 1.12 and 1.08 respectively. We conclude that to understand the hadronic associated WH0 production, it is necessary to study the NLO QCD corrections to the WH^0j production process which is part of the inclusive WH^0 production.

	3. Comparison Between Neural Networks and Fisher Discriminant for Continuum Background Suppression at Belle
	Liu Chao,Zhang Ziping
	Physics 31 August 2009
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:The neural networks method and fisher discriminant method for continuum background suppression are presented. We apply these two methods to the analysis on B-->K omega phi decay separately and compare the effects of the two methods. With neural network, we are able to preserve 42.3% of the BBbar events while rejecting 99.2% of continuum background. With fisher discriminant, we can preserve 57.9% of the signal while rejecting 98.6% of the continuum background.

	Abstract:We report on a search for the X(1812) state in the decay B->K omega phi with a data sample of 657×10^6 BBbar pairs collected with the Belle detector at the KEKB e^+e^- collider. No significant signal is observed. An upper limit B->K X(1812),X(1812)->omega phi)<3.2×10^{-7}(90% C.L.) is determined. We also constrain the three-body decay branching fraction to be Br(B->K omega phi)<1.9 ×10^{-6}（90% C.L.).

	Abstract:The Higgs-boson production in association with a W-boson pair at $e^+e^-$ linear colliders is one of the important processes in probing the coupling between Higgs-boson and vector gauge bosons and discovering the signature of new physics. We describe the impact of the complete electroweak(EW) radiative corrections of ${\\\\\\\\\\\\\\\\cal O}(\\\\\\\\\\\\\\\\alpha_{ew})$ to this process in the standard model(SM) at the International Linear Collider(ILC), and investigate the dependence of the lowest-order(LO) and EW next-to-leading order(NLO) corrected cross sections on colliding energy $\\\\\\\\\\\\\\\\sqrt{s}$ and Higg-boson mass. The LO and NLO EW corrected distributions of the invariant mass of W-boson pair and the transverse momenta of final $W$- and Higgs-boson are presented. Our numerical results show that the relative EW radiative correction($\\\\\\\\\\\\\\\\delta_{ew}$) varies from $-19.4\\\\\\\\\\\\\\\\%$ to $0.2\\\\\\\\\\\\\\\\%$ when $m_H=120~GeV$ and $\\\\\\\\\\\\\\\\sqrt{s}$ goes up from $300~GeV$ to $1.2~TeV$.

	Abstract:We study the complete ${cal O}(alpha_{ew})$ electroweak (EW) corrections to the production of three -bosons in the the framework of the standard model(SM) at the ILC. The leading order and the EW next-to-leading order corrected cross sections are presented, and their dependence on the colliding energy $sqrt{s}$ and Higgs-boson mass $m_{H}$ is analyzed. We investigate also the LO and one-loop EW corrected distributions of the transverse momentum of final $Z^0$ boson, and the invariant mass of $Z^0Z^0$-pair. Our numerical results show that the EW one-loop correction generally suppresses the tree-level cross section, and the relative correction with $m_{H}=120~GeV(150~GeV)$ varies between $-15.8%(-13.9%)$ and $-7.5%(-6.2%)$ when $sqrt{s}$ goes up from $350~GeV$ to $1~TeV$.

	Abstract:The aim of this paper is to suggest a vacuum fluctuations based model of photons and electrons. In doing this, three postulates of vacuum fluctuations are proposed first, which is consonant with the basic premises of relativity and quantum mechanics. As applications, the model is used to analyze the Compton effect and the electron-positron annihilation. It is found that calculations are simple, and the physical meaning is clear. Also, the spin of photons and electrons is discussed in a preliminary way.

	Abstract:We study the full contributions at the leading order(LO) and QCD next-to-leading order(NLO) to the cross section of the $e^+e^- \to W^+ W^- b\bar b$ process in the standard model(SM) at the ILC. In dealing the resonance problem we adopted the complex mass scheme in both tree-level and one-loop level perturbative calculations. Our numerical results show that the K-factor varies from $1.501$ to $0.847$ when $\sqrt{s}$ goes up from $360~GeV$ to $1.5~TeV$. We investigate the dependence of the LO and QCD NLO corrected cross sections of process $e^+e^- \to W^+ W^- b\bar b$ on colliding energy $\sqrt{s}$ and Higgs-boson mass. We also present the results of the LO and QCD NLO corrected distributions of the transverse momenta of final particles, and the invariant masses of $Wb$-, $b\bar b$- and $WW$-pair.

	Abstract:We add a nonstandard higgs into the traditional bosonic part of electroweak chiral Lagrangian, in purpose of finding out the contribution to EWCL coefficients from processes with internal line higgs particle. To construct the effective Lagrangian with higgs, we use low energy expansion scheme and write down all the independent terms conserving $SU(2)\times U_Y(1)$ symmetry in the nonlinear representation which we show is equivalent to the linear representation. Then we integrate out higgs using loop expansion technique at 1-loop level, contributions from all possible terms are obtained. We find up to order of $p^4$ in low energy expansion, three terms, $\mathcal{L}_5$, $\mathcal{L}_7$, $\mathcal{L}_{10}$ in EWCL are important, for which the contributions from higgs can be further expressed in terms of higgs partial decay width $\Gamma_{h\rightarrow ZZ}$ and $\Gamma_{h\rightarrow WW}$. Higg mass dependence of the coefficients in EWCL are discussed.
