Abstract

We report a measurement of D0-D̄0 mixing parameters in D0→KS0π+π- decays using a time-dependent Dalitz-plot analysis. We first assume CP conservation and subsequently allow for CP violation. The results are based on 540fb-1 of data accumulated with the Belle detector at the KEKB e+e- collider. Assuming negligible CP violation, we measure the mixing parameters x=(0.80±0.29-0.07-0.14+0.09+0.10)% and y=(0.33±0.24-0. 12-0.08+0.08+0.06)%, where the errors are statistical, experimental systematic, and systematic due to the Dalitz decay model, respectively. Allowing for CP violation, we obtain the CP-violating parameters |q/p|=0.86-0.29-0.03+0.30+0. 06±0.08 and arg (q/p)=(-14-18-3-4+16+5+2)°.

N2 - We report a measurement of D0-D̄0 mixing parameters in D0→KS0π+π- decays using a time-dependent Dalitz-plot analysis. We first assume CP conservation and subsequently allow for CP violation. The results are based on 540fb-1 of data accumulated with the Belle detector at the KEKB e+e- collider. Assuming negligible CP violation, we measure the mixing parameters x=(0.80±0.29-0.07-0.14+0.09+0.10)% and y=(0.33±0.24-0. 12-0.08+0.08+0.06)%, where the errors are statistical, experimental systematic, and systematic due to the Dalitz decay model, respectively. Allowing for CP violation, we obtain the CP-violating parameters |q/p|=0.86-0.29-0.03+0.30+0. 06±0.08 and arg (q/p)=(-14-18-3-4+16+5+2)°.
