摘要:
The mechanism of high-energyA′−A collisions (A>A′, A′
1/3≫1) and the space-time evolution of the fluid formed in the collision are analysed. The corresponding 1+1 dimensional hydrodynamic equations are set up. The average rapidity distributions are estimated and compared with cosmic ray data. The origin of the unsymmetry of rapidity distributions is explained.

摘要:
Based on the argument that the bag radius of a bounded nucleon is larger than that of a free one due to the change of vacuum property in nucleus, a good fit is obtained for the EMC effect.

摘要:
The authors present a new formulation of the two-fluid model, the thermal coherent state for handling the relativistic quantum field theory at finite temperature. Three models in one-dimensional space, the phi 4, sine-Gordon and the Schwinger model, are discussed.
