Statement of the selection committee:
Particle physics models containing extra dimensions have been actively studied as a candidate for solving the gauge-hierarchy problem of the standard model. In particular, those approaches drew attention after being pointed out that black holes might be produced in the collider experiment if the fundamental physical scale lies in TeV scale. In the earlier approaches, however, only very simple assumption about black holes had been adopted. This paper, for the first time, specifically obtained the spectrum of Hawking radiation by analysing field equations in 4 dimensional brane, and discussed a role of angular momentum in the production of black holes. In particular, their findings, that the produced black holes generally have a large angular momentum and a resulting Hawking radiation has a large anisotropy, greatly modified the previous naive approaches and gave a large impact to these approaches. Unfortunately, one of the co-authors, Daisuke Ida, does not qualify for this award. However, the selection committee equally praises his contribution for this work.
