	Abstract:During the commissioning of RPC detector systems at the Daya Bay Reactor Neutrino Experiment, calibration algorithms were developed and tuned, in order to evaluate and optimize the performance of the RPC detectors. Based on a description of the hardware structure of the RPC detector systems, this paper introduces the algorithms used for detector calibration, including trigger rate, efficiency, noise rate, purity and muon flux.

	Abstract:Using a data sample of 2.25*10^{8} J/ψ events collected with the BESIII detector, we present the first observation of the decays of η_{c} mesons to Sigma^{+} bar Sigma^{-} and Xi^{-} bar Xi^{+}. The branching fractions are measured to be (2.11\pm0.28_{\rm stat.}\pm0.18_{\rm syst.}\pm0.50_{\rm PDG})\times10^{-3} and (0.89\pm0.16_{\rm stat.}\pm0.08_{\rm syst.}\pm0.21_{\rm PDG})\times10^{-3} for η_{c} \to Sigma^{+} bar Sigma^{-} and Xi^{-} bar Xi^{+}, respectively. These branching fractions provide important information on the helicity selection rule in charmonium-decay processes.

	3. The Study of the contribution of the LHT model to Zbb coupling

	Abstract:In the framework of the Littlest Higgs Model with T-parity (LHT), we study the contributions of the new particles to Zbb couplings at one-loop level. Based on these results, we further study the branching ratio R_{b} and the unpolarized forward-backward asymmetry A_{FB}^{b}. We find that the correction of the new particles to Zbb couplings is mainly on the left-handed coupling and has small part of the parameter space to alleviate the deviation between theoretical predictions and experimental values. The precision measurement value of R_{b} can give severe constraints on the relevant parameters. The constraints from the precision measurement value of A_{FB}^{b} are very weak.

	Abstract:In the littlest Higgs model with T-parity(LHT), some new particles, such as the T-odd mirror quarks and goldstone bosons, can generate the contribution to some observables. We calculate their contribution to the Zcc coupling. Some observables are related to the Zcc coupling, for example, the effective vector and axial-vector Zcc coupling constants (g_{Vc},g_{Ac}) and the c-quark forward-backward asymmetry(A_{FB}^{c}). We give our predictions about g_{Vc},g_{Ac} in the LHT model and show the allowed regions of the mirror quark masses based on the experimental data of g_{Vc}-g_{Ac}.Then, we also give an explanation on A^{c}_{FB}.

	Abstract:In this work , the parameter space of the constrained MSSM is examined byconsidering various experimental constraints.For the dark matter sector, the neutralino dark matter is requiredto account for the relic density measured by the WMAP and satisfythe XENON limits on its scattering rate with the nucleon.For the collider constraints, all relevant direct andindirect limits has been considered,such as from LEP, Tevatron and LHC as well as the muonanomalous magnetic moment. Especially, for the limits from Bs→u+u-, its branching ratio is either directly consideredwith the latest LHC data or alternatively considered the double ratioof the purely leptonic decays defined by Br(Bs→u+u-)/Br(Bu→rvr)/ Br(Ds→rvr)/Br(D →rur)。Under these constraints,the lightest Higgs boson (h) in the CMSSM and NUHM2 is upper bounded by 124 GeV.For these models the di-photon Higgs signal at the LHC issuppressed relative to the SM prediction, and that the lower bound ofthe top-squark mass goes up with mh, reaching 600GeV for mh=124 GeV.

	Abstract:Motivated by the recent LHC hints of a Higgs boson around 125 GeV,a SM-like Higgs with the mass 123-127 GeV is assumed and itsimplication in low energy SUSY is studied by comparing the MSSM and NMSSM.This work considers various experimental constraints at 2σ level(including the muon g-2 and the dark matter relic density) andperforms a comprehensive scan over the parameter space of each model.Then in the parameter space which is allowed by current experimental constraintsand also predicts a SM-like Higgs in 123-127 GeV, the propertiesof the sensitive parameters (like the top squark mass and the trilinearcoupling At) are examined and the rates of the di-photon signal andthe VV(V=W,Z) signals at the LHC are calculated. The typical findings are: (i) In the MSSMthe top squark and At must be large and thus incur some fine-tuning,which can be much ameliorated in the NMSSM; (ii) In the MSSM a light stauis needed to make the di-photon rate of the SM-like Higgs exceed its SMprediction, while in the NMSSM the di-photon rate can be readily enhancedin several ways;(iii) In the MSSM the signal rates of pp→h→VV at the LHC are always suppressedcompared with their SM predictions, while in the NMSSM they may get enhanced;(iv) A large part of the parameter space so far survived will be soon covered by the expectedXENON100(2012) sensitivity (especially for the NMSSM).

	Abstract:Whether molecular states indeed exist in nature has beendisputed for a long time. Several new resonances have been observedin the recent experiments and they seem to be of exotic structuresand some of them have been proposed to be molecular states. The veryrecent observation of Zb(10610)[(10608.4pm±2.0) MeV] and Zb(10650)[(10653.2pm ±1.5) MeV] encourages the interpretation ofmulti-quark states. In the Beter-Salpeter (BS) approach, we studythe possibility if two heavy mesons can form a molecular state byexchanging light mesons. Our results indicate that two heavy mesonscan form an isospin singlet (I=0) bound state but cannot form anisospin triplet (I=1) when the contribution of σ- exchangeis reasonably small, i.e. as the coupling of σ with mesons gσ takes the value given in previous literatures. Thus weconclude that the newly observed Zb(10610) should not be amolecular state, but a tetraquark state instead, at most, thefraction of the molecular state in the physical resonance Zb(10610) is tiny.

	8. What do the radiative decays of X(3872) tell us

	Abstract:Since the discovery of X(3872), its structure has beenin ceaseless dispute. The Belle and Babar collaborations havemeasured the decay rates of X(3872)->π+π-π0J/Ψ and the data suggest that X(3872) may be a high-spincharmonium of 2-+ instead of other exotic assignments.Recently the radiative decays of X(3872) which may explicitlydetermine the quantum number and structure of X(3872), have beenmeasured by the two collaborations. In terms of the light frontquark model (LFQM) we calculate the rates of the radiative decaysX(3872)->J/Ψ(Ψ')γ supposing X(3872) to bea 2-+ charmonium. Within this framework, our theoreticalprediction on mathcalR(X(3872)->Ψ(1S)γ) isat order of 10-3 which is slightly lower than the Babar'sdata but close to the Belle's. Instead, our prediction onBR(X(3872)->Ψ'γ) is at order of10-5 if psi is a pure 2S state or 10-4 if psi isa 2S-1D mixture, which does not conflict with the upper boundset by the Belle collaboration, but is much lower than the Babar'sdata, The future measurements will accurately determine thisbranching ratio, thus if the future measurement decides thebranching ratio of BR(X(3872)->Ψ'γ)to be much larger than 10-4, the assignment of 2-+ forX(3872) should be ruled out. Since the signal of the radiativedecay is clean, it is worth careful study from both experimentaland theoretical aspects.

	Abstract:Many new physics models beyond the standard model (SM) predict the existence of the colorless gauge boson (Z′) and the color-octet coloron (Ba). In the context of the topcolor scenario, we consider the contributions of these new particles to the observables, which are related to the top quark pair production at the LHC. With reasonable values of the relevant free parameters, we find that these new gauge bosons can make a sizable deviation of the top spin correlations from the SM result.

	10. Quark Confinement from Topological Perspective

	Abstract:By using the physics of Wilson factor and Aharonov-Bohm effect, we find in the fluxtube-quark system the topology of a baryon consisting three heavy flavor quarks imitates that of the fractional quantum Hall effect (FQHE). This similarity yields the result that the constituent quarks of baryon have the "filling factor" , thus it gives us a rationale to the previous conjecture that quark confinement is a correlation effect was confirmed. Moreover, by deriving a Hamiltonian of the system analogous to that of FQHE, we predict an energy gap for the ground state of a heavy three-quark system.
