Heavy quark meson spectroscopy at CDF

Kai Yi

From a study of the X(3872) mass and width based on the world's largest sample of $X (3872) \to J / ψ π^{+} π^{-}$ decays, we find that our X(3872) signal is consistent with a single state,…

A Search for Invisible Decays of the Upsilon(1S)

The BABAR Collaboration, B. Aubert

We search for invisible decays of the Upsilon(1S) meson using a sample of 91.4 x 10^{6} Upsilon(3S) mesons collected at the BaBar/PEP-II B-factory. We select events containing the…

Properties of Exotic Charmonium-like States at CDF

Kai Yi

We report the recent evidence for a new narrow structure, Y(4140), decaying to the $J / ψ ϕ$ final state, in exclusive $B^{+} \to J / ψ ϕ K^{+}$ decays in a data sample corresponding to an int…

Time-dependent amplitude analysis of B0 --> K0S pi+ pi-

The BABAR Collaboration, B. Aubert

We perform a time-dependent amplitude analysis of $B^{0} \to K_{S}^{0} π^{+} π^{-}$ decays to extract the CP violation parameters of $f_{0} (980) K_{S}^{0}$ and $ρ^{0} (770) K_{S}^{0}$ and the direct CP asy…

Search for B^0 Meson Decays to π^0 K^0_SK^0_S, ηK^0_S K^0_S, and η^{\prime}K^0_SK^0_S

The BABAR Collaboration, B. Aubert

We describe searches for $B^{0}$ meson decays to the charmless final states $π^{0} K_{S}^{0} K_{S}^{0}$ , $η K_{S}^{0} K_{S}^{0}$ , and $η^{'} K_{S}^{0} K_{S}^{0}$ . The data sample corresponds to $467 \times 1…

Search for b-> u transitions in B0 -> D0 K*0 decays

The BABAR Collaboration, B. Aubert

We present a study of the decays B0 -> D0 K*0 and B0 -> barD0 K*0 with K*0 -> K+pi-. The D0 and the barD0 mesons are reconstructed in the final states f=K+pi-, K+pi-pi0, K+pi-pi+pi…
