LHC top mass: alternative methods and prospects for the future

Future lepton colliders will have a rich top quark physics program which would add to our understanding of this interesting quark and promise an ultimate precision on the experimental knowledge of top-quark mass. We present possible improvements in the understanding of systematic uncertainties for various top-quark mass measurement techniques at the LHC, including projections for running conditions foreseen in the future.Comment: Talk presented at the International Workshop on Future Linear Colliders (LCWS13), Tokyo, Japan, 11-15 November 201

Central Bank Interventions in the Yen-Dollar Spot Market

We test the effectiveness of Bank of Japan (BOJ)'s foreign exchange interventions on conditional first and second moments of exchange rate returns and traded volumes, using a bivariate EGARCH model of the Yen/USD market from 5-13-1991 to 6-28-2002. We also estimate a friction model of BOJ's intervention reaction function based on reducing short-term market disorderliness and supplementing domestic monetary policy. We find ineffectiveness of BOJ interventions pre-1995 but effectiveness post-1995, Fed intervention amplified the effectiveness of the BOJ transactions, BOJ's interventions were based on ‘leaning against the wind' motivations, and BOJ interventions were vigorously used in support of domestic monetary policy objectives pos t-1995.Foreign exchange intervention; Bank of Japan; exchange rate volatility; trade volume
