Selected physics results from Belle

We present an updated measurement of sin 2phi(1) in B-0 --> c (c) over barK decays and first evidence for CP-violating asymmetries in B --> pi(+)pi(-) decays. We also report the first observation of the, eta(c) (2S) meson. The results axe based on analyses of a sample of 41.8 million B (B) over bar meson pairs from the decays of the Y(4S) resonance, collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. For the. B --> pi(+)pi(-) CP-violating asymmetry measurement, we fully reconstruct one neutral B meson as a B --> pi(+)pi(-) CP eigenstate and identify the flavor of the accompanying B meson from its decay products. From the dependence of the asymmetry on the time intervals between the two B meson decay points, we obtain the CP-violating asymmetry parameters S-pipi = -1.21 (+0.38)(-0.27) (stat) (+0.16)(-0.13) (syst) and A(pipi) = +0.94 (+0.25)(-0.31) (stat) +/- 0.09(syst). In the eta(c) (2S) meson search, we examined the KSK- pi(+) invariant mass distribution in a sample of exclusive B --> KK(S)K(-)pi(+) decays. We find a narrow peak mass M = 3654 +/- 6(stat) +/- 8(syst) MeV/c(2) and width Gamma < 55MeV/(c)2. The properties agree with heavy-quark potential model expectations for the eta(c)(2S) meson, the n = 2 singlet S-wave charmonium state.
