SU(N)xSU(N)手征西格玛模型的有限体积质量间隙和自由能

Finite volume mass gap and free energy of the SU(N)xSU(N) chiral sigma model

Ferenc Niedermayer, Peter Weisz

摘要:

我们使用维度正则化计算了有效SU(N)xSU(N)标量场理论中存在与保守电荷耦合的化学势时的自由能,对于一般d维的非对称体积为三阶。我们还计算了有限盒周期边界条件下的质量间隙。

英文摘要:

We compute the free energy in the presence of a chemical potential coupled to a conserved charge in the effective SU(N)xSU(N) scalar field theory to third order for asymmetric volumes in general d-dimensions, using dimensional regularization. We also compute the mass gap in a finite box with periodic boundary conditions.
