Glueballs at physical pion mass
《Chinese Physics C》2023年第6期81-88,共8页陈飞宇 蒋翔宇 陈莹 刘克非 孙伟 杨一玻 
Supported by the Strategic Priority Research Program of Chinese Academy of Sciences(XDB34030300,XDPB15);the National Key Research and Development Program of China(2020YFA0406400);the National Natural Science Foundation of China(NNSFC)under Grants(11935017,12070131001)(CRC 110 by DFG and NNSFC);supported in part by a NSFC-DFG joint grant(12061131006 and SCHA458/22)。
Glueballs are investigated through gluonic operators on two N_(f)=2+1RBC/UKQCD gauge ensembles at the physical pion mass.The statistical errors of glueball correlation functions are considerably reduced through the cl...

Revisiting the determining fraction of glueball component in f_(0) mesons via radiative decays of J/ψ
《Chinese Physics C》2021年第2期133-143,共11页Xing-Dao Guo Hong-Wei Ke Ming-Gang Zhao Liang Tang Xue-Qian Li 
Supported by National Natural Science Foundation of China(11805160,11747040,11675082,11605039)。
QCD theory predicts the existence of glueballs,but so far all experimental endeavors have failed to identify any such states.To remedy this discrepancy between QCD,which has proven to be a successful theory for strong...

Gluon-pair-creation production model of strong interaction vertices
《Chinese Physics C》2020年第9期53-61,共9页Bing-Dong Wan Cong-Feng Qiao 
Supported in part by the Strategic Priority Research Program of the Chinese Academy of Sciences(XDB23030100);the National Natural Science Foundation of China(NSFC)(11975236,11635009)。
By studying theηc exclusive decay to double glueballs,we introduce a model to phenomenologically mimic the gluon-pair-vacuum interaction vertices,namely the 0^++model.Based on this model,we study glueball production ...

The lowest-lying glueballs are investigated in lattice QCD using Nf = 2 clover Wilson fermions on anisotropic lattices. We simulate at two different and relatively heavy quark masses, corresponding to physical pion ma...

Abelian-Higgs phase of SU(2) QCD and glueball energy被引量：2
《Chinese Physics C》2008年第7期509-514,共6页贾多杰 
Supported by National Natural Science Foundation of China(10547009);Research Backbone Fostering Program of Knowledge and S&T Innovation Project of NWNU(KJCXGC 03-41)
It is shown that SU（2） QCD admits an dual Abelian-Higgs phase, with a Higgs vacuum of a type-Ⅱ superconductor. This is done by using a connection decomposition for the gluon field and the random-direction approxima...
