| 抄録 | The W boson mass is measured through computer simulation at the proposed Joint Linear Collider (JLC) using its hadronic decay channel in the process e(+)e(-) to e(-)(nu-bar)W(+) to e(-)(nu-bar)q(q-bar). Effects of beamstrahlung (BM) and initial state radiation (ISR) are included in the mass measurement. An integrated luminosity of integration of L with respect to dt equal to 100 fb(sup -1) is assumed and the center-of-mass energy is set at square root of s equal to 500 GeV. Monte Carlo data is obtained and analyzed using the JLC Study Framework (JSF). Event generation is done using BASES/SPRING and Pythia. The 3 Tesla configuration of the JSF Quick Simulator is employed for the event simulation. Backgrounds are minimized by the formulated event selection criteria. The statistical error on the mass measurement is about 20 MeV and the mass shift from the input value is about 1 GeV. |
