强耦合下格点量子色动力学的核物理

Nuclear Physics from lattice QCD at strong coupling

Philippe de Forcrand, Michael Fromm

摘要:

数值研究了一类无质量交错夸克的格点量子色动力学的强耦合极限。我们确定了完整的相图作为温度和化学势的函数,包括一个三临界点。我们阐明了低温致密相的性质,它是强束缚的核物质。这种强结合可以用我们测量的核势来解释。最后,我们确定,从QCD的第一原理极限情况下,原子核的质量,直到A=12“碳”。

英文摘要:

We study numerically the strong coupling limit of lattice QCD with one flavor of massless staggered quarks. We determine the complete phase diagram as a function of temperature and chemical potential, including a tricritical point. We clarify the nature of the low temperature dense phase, which is strongly bound nuclear matter. This strong binding is explained by the nuclear potential, which we measure. Finally, we determine, from this first-principle limiting case of QCD, the masses of atomic nuclei up to A=12 "carbon".
