超新星中夸克相变的u,d夸克质量效应

Effect of u and d quark mass on the phase transition of quark matter in supernova

分析了超新星中从两味夸克物质到奇异夸克物质相变的u,d夸克质量作用,研究表明,相变平衡后,u,d夸克质量对夸克丰度、温度和中微子总能量的影响不大.在分析相变过程时,u,d夸克的质量可以忽略.进一步表明,夸克味(u,d)不是好的量子相变参量.光子的夸克结构模型也得到了支持.

The effect of u and d quark mass on the conversion of the two - flavor quark matter to more stable strange quark matter has been analyzed. It is shown that the u and d quark mass has slight influence on equilibrium parameters, involving quark temperature, quark abundances and total neutrino energies. So the u and d quark mass can reasonably be neglected when the conversion processes are studied in a supernova core. It further indicates that the u, d quarks are not good quantum transition flavors and the structure of photon comprised of quarks is also supported.
