Angles of the CKM Unitarity Triangle Measured at Belle
A. J. Schwartz
The Belle experiment has used several methods to measure or constrain the angles phi_1, phi_2, and phi_3 (or beta, alpha, and gamma) of the CKM unitarity triangle. The results are…
Search for D^0-\bar{D^0} mixing using semileptonic decays at Belle
U. Bitenc
A search for mixing in the neutral D meson system has been performed using semileptonic D^0 \to K^(*)- e^+ nu decays. Neutral D mesons from D^*+ \to D^0 pi+ decays are used; the fl…
Measurement of the wrong-sign decays D0 -> K+ pi- pi0 and D0 -> K+ pi- pi+ pi-, and search for CP violation
The Belle Collaboration, X. C. Tian
Using 281 fb^-1 of data from the Belle experiment recorded at or near the Upsilon(4S) resonance, we have measured the rates of the ``wrong-sign'' decays D0 -> K+ pi- pi0 and D0 ->…
Observation of a new charmonium state in double charmonium production in e+ e- annihilation at \sqrt{s} ~ 10.6 GeV
The Belle Collaboration, K. Abe
We report the first observation of a new charmonium state at a mass of . This state, called X(3940), is observed in the process $e^+ e^- \to…
Measurements of B Decays to Two Kaons
K. Abe
We report measurements of B meson decays to two kaons using 250/fb of data collected with the Belle detector at the KEKB asymmetric energy e+ e- collider. We find evidence of signa…
Observation of b --> d gamma and Determination of |V_td/V_ts|
D. Mohapatra
We report the observation of the flavor-changing neutral current process b --> d gamma using a sample of 386*10^6 B meson pairs accumulated by the Belle detector at the KEKB e+ e-…
