Relativistic Calculation of the Width of the Theta (1540) Pentaquark
Hu Li, C. M. Shakin, Xiangdong Li
We calculate the width of the Theta(1540) pentaquark in a relativistic model in which the pentaquark is considered to be composed of a scalar diquark and a spin 1/2 triquark. We co…
Description of Gluon Propagation in the Presence of an A^2 Condensate
Xiangdong Li C. M. Shakin
There is a good deal of current interest in the condensate A^2 which has been seen to play an important role in calculations which make use of the operator product expansion. That…
Quark Propagation in the Quark-Gluon Plasma
Xiangdong Li, Hu Li, C. M. Shakin +1
It has recently been suggested that the quark-gluon plasma formed in heavy-ion collisions behaves as a nearly ideal fluid. That behavior may be understood if the quark and antiquar…
Comparison of Temperature-Dependent Hadronic Current Correlation Functions Calculated in Lattice Simulations of QCD and with a Chiral Lagrangian Model
Bing He, Hu Li, C. M. Shakin +1
The Euclidean-time hadronic current correlation functions, and , of pseudoscalar and vector currents have recently been calculated in lattice simulations of…
Calculation of Temperature-Dependent Hadronic Correlation Functions of Pseudoscalar and Vector Currents
Bing He, Hu Li, C. M. Shakin +1
We make use of the Nambu-Jona-Lasinio (NJL) formalism and real-time finite-temperature field theory to calculate hadronic current correlation functions in the deconfined phase of q…
Calculation of the Pseudoscalar-Isoscalar Hadronic Current Correlation Functions of the Quark-Gluon Plasma
Bing He, Hu Li, C. M. Shakin +1
We report the results of calculations of pseudoscalar-isoscalar hadronic current correlators using the Nambu--Jona-Lasinio model and the real-time finite-temperature formalism. Res…
