微扰杂种优势弦理论发展了一个超过哈格多恩温度的单一复快子模。我们计算了在临界温度下这种快子模的四次有效势。等价地，我们利用小圆上费米子的反周期边界条件确定了超对称强破缺的四次有效势。我们给出了异质快子散射振幅的许多细节，包括一个么正性检查，以固定所有的归一化常数。我们讨论困难，在获得有效的行动有效的所有半径。我们认为，在某些变量，四次项的潜力是半径无关的。一个新的强烈弯曲的阶段，可能会发生快子凝聚后的属性的猜测。
Perturbative heterotic string theory develops a single complex tachyonic mode beyond the Hagedorn temperature. We calculate the quartic effective potential for this tachyonic mode at the critical temperature. Equivalently, we determine the quartic effective potential for strong supersymmetric breaking via anti-perdiodic boundary conditions for fermions on a small circle. We give many details of the heterotic tachyon scattering amplitudes, including a unitarity check to fix all normalization constants. We discuss difficulties in obtaining an effective action valid at all radii. We argue that in certain variables, the quartic term in the potential is radius independent. Speculations on the properties of a new strongly curved phase that could occur after tachyon condensation are offered.
