Description
Measurement of $\phi_3$ with a Dalitz Plot Analysis of $B^+ \to D^{(*)}K^+$ Decay
We present an update of the measurement of the unitarity triangle angle $\phi_3$ using a Dalitz plot analysis of three-body neutral D decays from $B \to D^{(*)}K$ process. The results are based on a large sample of $B\bar{B}$ decays recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+e^-$ collider.
Measurement of CPT Violating Parameter
CPT is expected to be a fundamental symmetry with no significant deviations. Nonetheless we can introduce an artificial perturbation parameter to the $B^0-\bar{B}^0$ mixing system that violates CPT symmetry. The CPT violating parameter, which is a complex number but expected to be zero, can be probed through proper time difference distributions in correlated B meson pair decays. We present a measurement of the CPT violating parameter using a large data sample collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB energy-asymmetric $e^+e^-$ collider.
Measurement of $CP$-violating Parameters in the $B\to K_S^0 K^+ K^-$ Time-dependent Dalitz Plot Analysis
We present a measurement of $CP$-violating parameters in the $B^0$ decays with $K_S^0 K^+ K^-$ final state including $B^0 \to \phi K_S^0$ using a time-dependent Dalitz plot analysis. The results are based on a large data sample of $B \bar{B}$ pairs collected on the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider.
Improved measurement of $CP$ asymmetries in $B^0 \to (c\bar{c}) K^0$ decays
We present results on time-dependent $CP$ asymmetries in the $B$ decays to neutral charmonium final states using a large dataset collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider.
