Study of CP-violation at the Belle experiment
… D0 π. The analysis was performed using the final Belle dataset containing 772 × 106 B ¯B pairs collected at the KEKB e+ e− collider. Three D0 decay modes are analyzed, K∓ π± , K∓ π± π0 , and K∓ π± π∓ π± . Since the studied decay is a scalar → vector vector decay, three helicity configurations are …

Search the decay of the B meson to two leptons at the Belle Experiment
… applied to 85 million BB events collected at the Belle experiment in Tsukuba, Japan, the resulting upper limits on branching fractions were 8.8×10⁻⁸ for B⁰ → e⁺e⁻, 1.0×10⁻⁷ for B⁰ → μ⁺μ⁻, and 8.5×10⁻⁸ for B⁰ → e±μ∓" at the 90% confidence level.

Analysis of B Meson Decays to Three Charged Pions
… sample of 772 million BB pairs collected by the Belle experiment, we present a study of direct CP violation in the decay of charged B to three charged pions.

Determination of the X(3872) Meson Quantum Numbers
… Collider beauty (LHCb) is one of the several experiments located at the ring of the Large Hadron Collider (LHC) in Geneva. The LHCb detector is a single arm forward spectrometer and is designed to perform high precision measurements of Charge Parity (CP) violation parameters and rare decays of …
