    In the Littlest Higgs model with T-parity, we study production processes of new gauge bosons at the international linear collider (ILC). Through Monte Carlo simulations of the production processes, we show that the heavy gauge boson masses can be determined very accurately at the ILC for a representative parameter point of the model. From the simulation result, we also discuss the determination of other model parameters at the ILC.Comment: 4 pages, 2 figures. Talk given at LCWS08, Chicago, November 200

    Precision Measurements of Little Higgs Parameters at the International Linear Collider

    We investigate a possibility of precision measurements for parameters of the Littlest Higgs model with T-parity at the International Linear Collider (ILC). The model predicts new gauge bosons (AH, ZH, and WH), among which the heavy photon (AH) is a candidate for dark matter. The masses of these new gauge bosons strongly depend on the vacuum expectation value that breaks a global symmetry of the model. Through Monte Carlo simulations of the processes: e+ e- ->AH ZH and e+ e- -> WH+ WH-, we show how precisely the masses can be determined at the ILC for a representative parameter point of the model. We also discuss the determination of the Little Higgs parameters and its impact on the future measurement of the thermal abundance of the dark matter relics in our universe.Comment: 22 pages, 10 figures, 6 tabl

    This study was performed to clarify the roles of reduced glutathion (GSH), superoxide dismutase (SOD), and solcosaryl in ischemic damage and reperfusion injury to the warm ischemic lungs of experimental animals. Fifty-one warm ischemic canine lungs were made by hilar stripping and clamping of the left PA, PV and bronchus for 2-3 hours. In the Non-perfusion group, GSH (50mg/ kg, I. V.: Group II) and solcoseryl (50mg/kg, I. V.: Group III) were administered. In the perfusion group, Euro-Collins (E-C) solution (20ml/kg) was perfused (Group IV) and GSH (1mg/ml in E-C solution: Group V) and SOD (15mg/l in E-C solution : Group VI) were used for anti-oxidative drugs. The pulmonary arterial pressure and aortic pressure were measured and also blood gas analysis was made during the preischemic period , immediately after, one hour and 3 days after reperfusion. Small parts of pulmonary tissues were taken for pathological examination one hour and 3 days after reperfusion. Chest X-ray films were teken at 3 days after the operation. GSH, SOD, and solcoseryl effectively act as scavengers of active oxygen species (AOS) , especially in terms of oxygenation. In the group with anti-oxidative drugs, cytoprotective effects of the pathological and chest X-ray findings on ischemic damage and reperfusion injury were much more manifest rather than those in control groups
