Measurement of the CP-violating phase $β$ in $B^{0} \to J / ψ π^{+} π^{-}$ decays and limits on penguin effects

LHCb collaboration, R. Aaij, B. Adeva +697

Time-dependent CP violation is measured in the $B^{0} \to J / ψ π^{+} π^{-}$ channel for each $π^{+} π^{-}$ resonant final state using data collected with an integrated luminosity of 3.0 f…

Measurement of the $D^{0} \to π^{-} e^{+} ν_{e}$ differential decay branching fraction as a function of $q^{2}$ and study of form factor parameterizations

J. P. Lees

Based on a sample of 500 million $e^{+} e^{-} \to c c ˉ$ events recorded by the BaBar detector at c.m. energies of close to 10.6 GeV, we report on a study of the decay $D^0 \to π^- e^…

Measurement of the inelastic $pp$ cross-section at a centre-of-mass energy of $s = 7$ TeV

LHCb collaboration, R. Aaij, B. Adeva +699

The cross-section for inelastic proton-proton collisions, with at least one prompt long-lived charged particle of transverse momentum $p_{T} > 0.2$ GeV/ $c$ in the pseudorapidity…

Dalitz plot analyses of $B^{0} \to D^{-} D^{0} K^{+}$ and $B^{+} \to D^{0} D^{0} K^{+}$ decays

The BABAR Collaboration, J. P. Lees, others

We present Dalitz plot analyses for the decays of $B$ mesons to $D^{-} D^{0} K^{+}$ and $D^{0} D^{0} K^{+}$ . We report the observation of the $D_{s 1}^{*} (2700)^{+}$ resonance in these…

Search for long-lived particles decaying to jet pairs

LHCb collaboration, R. Aaij, B. Adeva +699

A search is presented for long-lived particles with a mass between 25 and 50 GeV $/ c^{2}$ and a lifetime between 1 and 200 ps in a sample of proton-proton collisions at a centre-of-ma…

Search for new $π^{0}$ -like particles produced in association with a $τ$ -lepton pair

The BABAR Collaboration, J. P. Lees, others

We report on a search in $e^{+} e^{-}$ annihilations for new $π^{0}$ -like particles produced in association with a $τ$ -lepton pair. These objects, with a similar mass and similar decay mo…
