核物质中核子的QCD求和定则

QCD sum rule for nucleon in nuclear matter

S. Mallik, Sourav Sarkar

摘要:

本文考虑了核物质中核子流的两点函数,并写出了一个QCD求和规则来分析核子极的留数作为核密度的函数。求和规则所需的核子自能被作为使用唯象NN势计算的输入。我们的结果表明,随着核密度的增加,残留量减少,这是已知的情况下,类似的数量。

英文摘要:

We consider the two-point function of nucleon current in nuclear matter and write a QCD sum rule to analyse the residue of the nucleon pole as a function of nuclear density. The nucleon self-energy needed for the sum rule is taken as input from calculations using phenomenological NN potential. Our result shows a decrease in the residue with increasing nuclear density, as is known to be the case with similar quantities.
