Recent Charm Physics Results from BaBar
Creators
Description
I present recent results from the BaBar experiment based on a data sample corresponding to an integrated luminosity of about 480 fb−1 collected at the PEP-II asymmetric energy e+e− collider. In particular, I will discuss the search for CP violation in D+→Ks0K+ and Ds+→Ks0K+,Ks0π+ decays, and in three-body D+→K+K−π+ decays. I will report on the measurement of the mixing parameter yCP and of the CP-violation parameter ΔY, in the lifetime ratio analysis of the transitions to the CP-even eigenstates D0→K+K−,π+π−, relative to the transitions to the CP-mixed state D0→K−π+, where we obtain yCP=[0.72±0.18(stat)±0.12(syst)]% and ΔY=[0.09±0.26(stat)±0.06(syst)]%. Finally, I will present a precision measurement of the D⁎(2010)+ total width, Γ=83.5±1.7(stat)±1.2(syst) keV, and of the D⁎(2010)+−D0 mass difference, Δm=145426.5±0.4(stat)±2.6(syst) keV
