具有破标度的手征拉格朗日量:一个考虑声子场热贡献的Fortran程序

A chiral lagrangian with broken scale: a Fortran code with the thermal contributions of the dilaton field

Luca Bonanno

摘要:

手征膨胀子模型是一种手征拉格朗日量,其中标度不变性的破缺由一个称为标量子的标量场的期望值来调节。在这里,我们提供了一个Fortran代码\cite{epaps,ind},作为一个工具,使计算内的手征膨胀模型在有限的密度和温度。通过包括介子场的热贡献,相对于以前的工作[arXiv:0704.3707,arXiv:0805.4188]改进了计算。

英文摘要:

The Chiral Dilaton Model is a chiral lagrangian in which the breaking of scale invariance is regulated by the expectation value of a scalar field, called dilaton. Here we provide a Fortran code \cite{epaps,ind}, as a tool to make calculations within the Chiral Dilaton Model at finite density and temperature. The calculations are improved respect to previous works [arXiv:0704.3707,arXiv:0805.4188] by including the thermal contributions of the dilaton field.
