强磁场、高温和密度对QCD相关现象的影响

Effects of Intense Magnetic Fields, High Temperature and Density on QCD-Related Phenomena

Jorge David Castaño-Yepes

摘要:

从不同的角度研究了高温、稠密体系和强磁场对量子色动力学相关现象的影响:在高温和稠密体系中,从线性西格玛模型的角度计算了QCD相图。在强磁场和高胶子密度下,胶子熔合和胶子分裂通道被认为是新的光子产生源,从而更好地解释了所谓的“光子之谜”中的实验数据。最后,编码到极化张量的胶子的热屏蔽和磁屏蔽性质的德拜质量。

英文摘要:

The effects of high-temperature, dense systems, and strong magnetic fields on Quantum Chromodynamics related phenomena are studied in different perspectives: in the high-temperature and densities, the QCD-phase diagram from the Linear Sigma Model point of view is computed. In particular, the CEP location and transition lines for chiral restoration were found. In the intense magnetic fields and high-gluon density, the gluon fusion and gluon splitting channels are proposed as new photon production sources to better explain the experimental data in the so-called "photon puzzle". Finally, the thermal and magnetic screening properties for gluons encoded into the polarization tensor were addressed in terms of the Debye mass.
