扩展的八夸克相互作用PNJL模型的奇异临界端点和等熵轨线

The strange critical endpoint and isentropic trajectories in an Extended PNJL Model with Eight Quark Interactions

Renan Câmara Pereira, João Moreira, Pedro Costa

摘要:

在这项工作中,我们探讨了几个关键端点的可能存在的强相互作用物质的相图使用扩展PNJL模型与't Hooft行列式和八夸克相互作用的上,下和奇怪的部门。此外,我们还研究了在交叉区和一级相变区中穿过(轻的和奇怪的)手征相变和临界端点附近的等熵轨迹。

英文摘要:

In this work, we explore the possible existence of several critical endpoints in the phase diagram of strongly interacting matter using an extended PNJL model with 't Hooft determinant and eight quark interactions in the up, down and strange sectors. Besides, we also study the isentropic trajectories crossing both (light and strange) chiral phase transitions and around the critical endpoint in both the crossover and first-order transition regions.
