重离子碰撞中宇称违反退禁闭物质的自由磁化结
Free magnetized knots of parity-violating deconfined matter in heavy-ion collisions
摘要:
我们证明了在夸克-胶子等离子体中的局域宇称破缺支持了由超强磁场稳定的退禁闭热夸克物质的自由(Meta)稳定结的存在。结中的磁场类似于核聚变的磁约束方法中的球马克等离子体状态。结的大小是量子化的,与夸克-胶子等离子体的手征电导率成反比。宇称对称性在纽结内部被打破。在结的衰变中产生的颗粒具有不寻常的方位角分布和特定的风味含量。我们认为,这些结可能会产生在非中心重离子碰撞。
英文摘要:
We show that the local parity violation in the quark-gluon plasma supports existence of free (meta)stable knots of deconfined hot quark matter stabilized by superstrong magnetic fields. The magnetic field in the knots resembles the spheromak plasma state of the magnetic confinement approach to nuclear fusion. The size of the knot is quantized, being inversely proportional to the chiral conductivity of the quark-gluon plasma. The parity symmetry is broken inside the knot. Particles produced in the decays of the knots have unusual azimuthal distribution and specific flavor content. We argue that these knots may be created in noncentral heavy-ion collisions.
