Vacuum Misalignment in High Energy Collisions
Zheng Huang
Abstract
We study a recent proposal to observe the disoriented chiral condensate in high energy collisions. In order to produce a large fluctuation in pion probability distribution, a large size of the correlated region is essential. We study the role of the intrinsic symmetry breaking and suggest that a negative (mass)2 of mesons arising from a misaligned vacuum may be a candidate for such a mechanism. We further point out a possibility to observe unsuppressed strong CP violation in the disoriented vacuum phase.
