Abstract

We report a new sensitive search for CPT violation, which includes improved measurements of the CPT-violating parameter z and the total decay-width difference normalized to the averaged width ΔΓ d/ Γ d of the two B d mass eigenstates. The results are based on a data sample of 535×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e +e - collider. We obtain Re(z)=[+1.9±3.7(stat) ±3.3(syst)]×10 -2, Im(z)=[-5.7±3.3(stat)±3. 3(syst)]×10 -3, and ΔΓ dd=[-1.7±1.8(stat)±1.1(syst)]×10 -2, all of which are consistent with zero. This is the most precise single measurement of these parameters in the neutral B-meson system to date.

N2 - We report a new sensitive search for CPT violation, which includes improved measurements of the CPT-violating parameter z and the total decay-width difference normalized to the averaged width ΔΓ d/ Γ d of the two B d mass eigenstates. The results are based on a data sample of 535×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e +e - collider. We obtain Re(z)=[+1.9±3.7(stat) ±3.3(syst)]×10 -2, Im(z)=[-5.7±3.3(stat)±3. 3(syst)]×10 -3, and ΔΓ d/Γ d=[-1.7±1.8(stat)±1.1(syst)]×10 -2, all of which are consistent with zero. This is the most precise single measurement of these parameters in the neutral B-meson system to date.

AB - We report a new sensitive search for CPT violation, which includes improved measurements of the CPT-violating parameter z and the total decay-width difference normalized to the averaged width ΔΓ d/ Γ d of the two B d mass eigenstates. The results are based on a data sample of 535×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e +e - collider. We obtain Re(z)=[+1.9±3.7(stat) ±3.3(syst)]×10 -2, Im(z)=[-5.7±3.3(stat)±3. 3(syst)]×10 -3, and ΔΓ d/Γ d=[-1.7±1.8(stat)±1.1(syst)]×10 -2, all of which are consistent with zero. This is the most precise single measurement of these parameters in the neutral B-meson system to date.
