我们认为，最小超对称标准模型(MSSM)的扩展可以产生可行的热膨胀，因此不存在Polonyi或模问题，它应该包含右手中微子，由于驱动热膨胀的Flaton的真空期望值，这些中微子获得了质量。这强烈反对如此(10)大一统理论。MSSM的{Mu}项也应因Flaton的VEV而出现。在额外假设的情况下，{ital m}{sup 2}{Sub{ital L}}{减号}{ital m}{sub{italH}{sub{itu}{sup 2}{lt}0，但是，当然，{ital m}{sup 2}{Sub{italL}}{减号}{italm}{sub{italH}{sub{itu}{sup 2}+{vert_bar}{u}{vert_bar}{sup 2}{gt}0，我们发现，采用{italLh}{subitalu}}{italD}平坦方向的复杂的Affleck-Dine型重子发生可以自然地产生宇宙的重子不对称。{版权所有}{1996年美国物理学会。}
We argue that an extension of the minimal supersymmetric standard model (MSSM) that gives rise to viable thermal inflation, and so does not suffer from a Polonyi or moduli problem, should contain right-handed neutrinos which acquire their masses due to the vacuum expectation value of the flaton that drives thermal inflation. This strongly disfavors SO(10) grand unified theories. The {mu} term of the MSSM should also arise due to the VEV of the flaton. With the extra assumption that {ital m}{sup 2}{sub {ital L}}{minus}{ital m}{sub {ital H}{sub {ital u}}}{sup 2}{lt}0, but, of course, {ital m}{sup 2}{sub {ital L}}{minus}{ital m}{sub {ital H}{sub {ital u}}}{sup 2}+{vert_bar}{mu}{vert_bar}{sup 2}{gt}0, we show that a complicated Affleck-Dine-type baryogenesis employing an {ital LH}{sub {ital u}} {ital D}-flat direction can naturally generate the baryon asymmetry of the Universe. {copyright} {ital 1996 The American Physical Society.}
