The workshop,“ Focus workshop also clarified the importance Week on LHC Phenomenology”, was of follow-up visitor programs, such as organized by Mihoko Nojiri (PI of IPMU) one month stays to finalize the projects and held at the IPMU, Research Center started in this meeting.” Building, on the Kashiwa campus. Many theorists found the discussion The Large Hadron Collider (LHC) at with experimentalists extremely CERN in Switzerland will start operating important, and vice verse.“ We in 2008. The aim of the meeting was to developed a consensus that it is bring together leading experimentalists important to set a series of workshops and phenomenologists working on LHC, to understand phenomena at the LHC to come up with new idea on physics and to maximize the performance of beyond the standard model. To reach the new physics searches,”remarked Launch of IPMU this goal, it is necessary to understand Nojiri. The University of Tokyo’s newly phenomena in the standard model: founded Institute for the Physics and deep theoretical understanding of the Mathematics of the Universe (IPMU) , standard model, and thus processes was launched on October 1, 2007. and responses involved in the LHC IPMU has been approved as one of the experiments, is essential to identify World Premier International Research effects of the new physics in the Center Initiatives (WPI) of the Ministry experiments. of Education, Culture, Sports, Science The following invited speakers with a and Technology (MEXT).

To overcome this, the focus prize, together with Andrew Strominger week followed the format propose and Cumrun Vafa of Harvard University. by Hitoshi Murayama. In the morning The award ceremony on January 7 was the participants had a few long talks, held during the Annual Meeting of the and in the afternoon they had time for AMS in San Diego, California. intense discussions. On the second day The prize was awarded to them for the workshop was held with 11 talks by their study on properties of black holes contributors.“ The format worked very using string theory and the forefront of well,” commented Murayama,“ many six-dimensional geometry.
