非对称冻结的么正性约束

Unitarity constraints on asymmetric freeze-in

Anson Hook

摘要:

本文考虑了不对称冻结的么正性和CPT约束,利用冻结在暗扇区中存储重子数。在这种情况下,萨哈罗夫的平衡条件是满足放置在不同的温度下的可见和隐藏的部门,而净可见重子数是通过存储在暗部门的负重子数。结果表明,酉性和CPT导致意外取消。特别地,重子数的转移在首阶完全取消。

英文摘要:

This paper considers unitarity and CPT constraints on asymmetric freeze-in, the use of freeze-in to store baryon number in a dark sector. In this scenario, Sakharov's out of equilibrium condition is satisfied by placing the visible and hidden sectors at different temperatures while a net visible baryon number is produced by storing negative baryon number in a dark sector. It is shown that unitarity and CPT lead to unexpected cancellations. In particular, the transfer of baryon number cancels completely at leading order.
