Unitary coupled-channels model for three-mesons decays of heavy mesons
heavy-meson hadronic decay exotic meson 3-body unitarity
2011/7/21
A unitary coupled-channels model is presented for investigating the decays of heavy mesons and excited meson states into three light pseudoscalar mesons. The model accounts for the three-mesons final ...
$Z_b(10610)$ and $Z_b(10650)$ structures produced by the initial single pion emission in the $Υ(5S)$ decays
$Z_b(10610)$ $Z_b(10650)$ initial single pion emission
2011/7/21
We propose an unique mechanism called {\it Initial Single Pion Emission} existing in the $\Upsilon(5S)$ decays, and further study the line shapes of $d\Gamma(\Upsilon(5S\to \Upsilon(nS)\pi^+\pi^-))/dm...
Measurement of the nuclear modification factor of electrons from heavy-flavour decays at mid-rapidity in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV with ALICE
nuclear modification electrons heavy-flavour decays Pb-Pb collisions
2011/7/21
We present results on inclusive electrons for 1.5 $ < p_{\rm T} < $ 6 GeV/$c$ in {Pb-Pb} collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV measured with ALICE at the LHC and compare these to a cocktail of ...
Radiative decays of dynamically generated charmed baryons
Radiative decays of dynamically charmed baryons
2011/1/10
In this work we study the radiative decay of dynamically generated JP = 12 − charm baryons into the ground state JP = 1 2 + baryons. Since different theoretical interpretations of these baryonic...
We study in this work the two-body hadronic charmed meson decays, including both the PP and VP modes. The latest experimental data are first analyzed in the diagrammatic approach. The magnitudes and s...
Rare semileptonic decays of heavy mesons in the heavy quark limit
weak decay heavy quark flavor symmetry
2010/1/18
We study the branching ratios of D+→D0e+ν, D+S→D0e+ν, B0S→B+e－ν, D+S→D+ e－e+ and B0S→B0e－e+ rare semileptonic decay processes, which are induced by decays of light quarks, the heavy quarks remain unch...
Study of semileptonic decays Bs→Ds1(2536)lν and Bs→Ds2(2573) lν in the CQM model
semileptonic decay CQM model branching ratios
2009/8/14
Based on the assumption that Ds1(2536) and Ds2(2573) belong to T doublet (1+,2+), we calculate the semileptonic decays of Bs to Ds1(2536) and Ds2(2573) in terms of the Constituent Quark Meson (CQM) mo...
Some topics on charmonium decays at BESⅢ experiment

2009/8/14
The construction of BESⅢ detector has been finished and the data taking is under plan. Some physics topics on charmonium decays at BESⅢ experiment are discussed in this paper. The measurement of prope...
A Method for Identifying Gluon Jets with High Purity in 3-jet Hadronic Z Decays
Three-Jet Gluon purity B-tag Z Boson
2010/4/13
A method for identifying gluon jets with very high purity is presented and the performance evaluated. Quark and gluon jets from Monte Carlo simulated Hadronic Z decays are identified by energy ordered...
