HAPPEN TO BE FASHIONABLE? : NEW PRACTICE CREATION THROUGH THE SEQUENCE OF MULTIPLE ACTORS

In contrast to previous research, this paper illustrates a process in which institutional entrepreneurs play less significant roles in creating a new practice. We drew on a historical case study that deals with the emergence of a new practice of emphasizing fashionable design of a type of clothing known as meisen. In the historical case study, multiple actors played distinctive and essential roles, which, as a whole, led to the creation of a new practice.

Future Prospects for Stau in Higgs Coupling to Di-photon

We study future prospects of the stau which contributes to the Higgs coupling to di-photon. The coupling is sensitive to new physics and planned to be measured at percent levels in future colliders. We show that, if the excess of the coupling is measured to be larger than 4 %, the lightest stau is predicted to be lighter than about 200 GeV by taking vacuum meta-stability conditions into account. Such a stau can be discovered at ILC. Moreover, we show how accurately the stau contribution to the coupling can be reconstructed from the information that is available at ILC. We also argue that, if the stau mixing angle is measured, the mass of the heaviest stau can be predicted by measuring the Higgs coupling, even when the heaviest stau is not yet discovered at the early stage of ILC.Comment: 16 pages, 4 figures, 1 table; references added, to be published in JHE

Mass Insertion Formula for Chargino Contribution to \Delta B = 1 Wilson Coefficients and its Application to CP Asymmetries of B \to K\pi

The comprehensive mass insertion formula of the b \to s \bar q q transitions was provided for the chargino contributions. The method clarifies physics behind the calculations of the supersymmetric contributions to FCNCs. The result was applied to the analysis of the difference of the CP asymmetries of the B \to K\pi decays. It is shown that the supersymmetry is not responsible for the discrepancy
