The proposed research covers the fields of gravitational physics, Quantum Fields and String Theory. The PI proposes to use cosmic ray data that will soon be available to see if TeV scale gravity is a viable theory. If so he intends to extract information about the extra dimensions, as well as the Hawking temperature from the data. The PI hopes to improve on the current semi-classical theory of Black Hole formation and evaporation. In this vein, he intends to investigate whether the black hole formation can be extracted from current ideas from string theory concerning D-brane collapse. The PI also intends to study antisymmetric tensor fields in four dimensions as well as solitons in N=2 gauge theories. Finally the PI hopes to extend to string theory language the idea that the smallness of the cosmological constant might be due to the instability of de Sitter space due to particle production.

拟议的研究涵盖了引力物理，量子场和弦理论的领域。 PI建议使用宇宙射线数据，以查看TEV量表重力是否是可行的理论。如果是这样，他打算从数据中提取有关额外维度以及鹰温度的信息。 PI希望改善当前黑洞形成和蒸发的半古典理论。在这种情况下，他打算研究是否可以从有关d-brane崩溃的弦理论中提取黑洞的形成。 PI还打算在四个维度以及n = 2量规理论中研究反对称张量场。最终，PI希望将弦理论语言扩展到宇宙常数的较小性可能是由于粒子产生而导致的安慰剂空间的不稳定所致。
