Phase diagram of two-color QCD matter at finite baryon and axial isospin densities
《Chinese Physics C》2020年第3期129-136,共8页Jingyi Chao 
Supported by the NSFC(11605254);Major State Basic Research Development Program in China(2015CB856903)
We study the two-color QCD matter with two fundamental quark flavors using the chiral perturbation theory and the Nambu-Jona-Lasinio(NJL)model.The effective Lagrangian is derived in terms of mesons and baryons,i.e.diq...

Diquark mass differences from unquenched lattice QCD
《Chinese Physics C》2016年第7期43-54,共12页毕玉江 蔡浩 陈莹 宫明 刘朝峰 乔豪学 杨一玻 
Supported by National Science Foundation of China(11575197,10835002,11405178,11335001);joint funds of NSFC(U1232109);MG and ZL are partially supported by the Youth Innovation Promotion Association of CAS(2015013,2011013);YC and ZL acknowledge support of NSFC and DFG(CRC110)
We calculate diquark correlation functions in the Landau gauge on the lattice using overlap valence quarks and 2＋1flavor domain wall fermion configurations. Quark masses are extracted from the scalar part of quark pr...

Non-Perturbative Analysis of Various Mass Generation by Gluonic Dressing Effect with the Schwinger-Dyson Formalism in QCD
《Journal of Modern Physics》2016年第8期790-805,共16页Shotaro Imai Hideo Suganuma 
As a topic of “quantum color dynamics”, we study various mass generation of colored particles and gluonic dressing effect in a non-perturbative manner, using the Schwinger-Dyson (SD) formalism in (scalar) QCD. First...

Discussions on the stability of diquarks
《Chinese Physics C》2012年第7期578-584,共7页汤亮 李学潜 
Supported by National Natural Science Foundation of China (11075079)
Since the birth of the quark model, the diquark, which is composed of two quarks, has been considered as a substantial structure of a color anti-triplet. This is not only a mathematical simplification for dealing with...

Ground State Mass Spectrum for Scalar Diquarks with Bethe-Salpeter Equation
《Communications in Theoretical Physics》2007年第2期287-292,共6页WANG Zhi-Gang WAN Shao-Long YANG Wei-Min 
The project supported by National Natural Science Foundation of China under Grant No. 10405009 The authors are indebted to Dr： J. He （IHEP）, Dr. X.B. nuang （PKU） and Dr. L. Li （GSCAS） for numerous help. Without them, the work would not be finished. The authors would also like to thank Prof. C.D. Roberts for providing us some important literatures.
In this article, we study the structures of the pseudoscalar mesons π, K and the scalar diquarks U^a, D^a, Sa in the framework of the coupled rainbow Schwinger-Dyson equation and ladder Bethe-Salpeter equation with t...

Tetraquarks Production in Quark-Gluon Plasma with Diquarks
《Chinese Physics Letters》2006年第3期568-571,共4页马忠彪 高崇寿 
Supported by the National Natural Science Foundation of China under Grant No 10055003, and by the Knowledge Innovation Project of Chinese Academy of Sciences under Grant No KJCX2-SW-N02.
We present a way to calculate tetraquarks ratios for quark gluon plasma with diquarks, The ratios of tetraquarks over baryons produced from quark matter are high than hadronic gas model limits. It is a better way to s...
