Abstract
The basic properties of the confinement mechanism in QCD—the temperature dependence of the spatial and temporal string tensions (\({{\sigma }_{{\text{s}}}}(T)\) and \({{\sigma }_{{\text{E}}}}(T)\))—are studied in the framework of the Field Correlator Method (FCM). It is shown that both functions are connected respectively to the spatial and temporal parts of the vacuum gluon energy \({{\epsilon }_{{\text{s}}}}\) and \({{\epsilon }_{{\text{E}}}}\) which define their equal values at \(T = 0\). However at \(T > 0\) the spatial part is growing with T while the temporal part is destroyed by the hadronic pressure at \(T = {{T}_{{\text{c}}}}\) (the deconfinement). Both properties are derived within the same method and are in a good agreement with the corresponding lattice data.
期刊介绍:
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
