标题： Fission and Fusion Bound States of p-brane Solitons

摘要： 超对称$p$-膜，它们携带单一的电荷或磁荷，并且保留$1/2$的超对称性，已被解释为所有超对称$p$-膜可以作为束缚态构建的基本组分，尽管结合能为零。 在这里，我们将讨论扩展到非超对称$p$-膜，并认为它们也可以被解释为相同基本超对称组分的束缚态。 一般来说，结合能是非零的，根据所选组分的不同，可以是正的或负的。 特别是，我们发现$a=0$ Reissner-Nordstr\o{m} 黑洞在$D=4$中可以由不同的组分集构建，使其具有零、正或负的结合能。 显示英文摘要

摘要： Supersymmetric $p$-branes that carry a single electric or magnetic charge and preserve $1/2$ of the supersymmetry have been interpreted as the constituents from which all supersymmetric $p$-branes can be constructed as bound states, albeit with zero binding energy. Here we extend the discussion to non-supersymmetric $p$-branes, and argue that they also can be interpreted as bound states of the same basic supersymmetric constituents. In general, the binding energy is non-zero, and can be either positive or negative depending on the specific choice of constituents. In particular, we find that the $a=0$ Reissner-Nordstr\o{m} black hole in $D=4$ can be built from different sets of constituents such that it has zero, positive or negative binding energy.
