QCD C-破缺相中的重子流

Baryon currents in the C-broken phase of QCD

Biagio Lucini, Agostino Patella, Claudio Pica

摘要:

在具有足够小的紧致维数(具有非平凡圈)和费米子周期边界条件的空间中,QCD中的电荷共轭(C)、空间宇称(P)、时间反演(T)和CPT对称性自发破缺。我们已经研究了这些离散对称性破缺的物理后果,也就是说,什么样的局部观测量可以用来检测它。我们表明,破缺诱导产生重子流,沿着紧凑的维传播。

英文摘要:

In a space with some sufficiently small compact dimension (with non-trivial cycles) and with periodic boundary conditions for the fermions, the charge conjugation (C), spatial parity (P), time reversal (T) and CPT symmetries are spontaneously broken in QCD. We have investigated what are the physical consequences of the breaking of these discrete symmetries, that is what local observables can be used to detect it. We show that the breaking induces the generation of baryon currents, propagating along the compact dimensions.
