Search for a Low-Mass Scalar Higgs Boson Decaying to a Tau Pair in Single-Photon Decays of Upsilon(1S)

J. P. Lees, others

We search for a low-mass scalar CP-odd Higgs boson, A0, produced in the radiative decay of the Upsilon resonance and decaying into a tau+tau- pair: Upsilon(1S)->gamma A0. The produ…

The branching fraction of tau --> pi- K0S K0S (pi0) nu decays

J. P. Lees

We present a study of tau- --> pi- K0S K0S (pi0) nu and tau- --> K- K0S K0S (pi0) nu decays using a dataset of 430 million tau lepton pairs, corresponding to an integrated luminosi…

Search for resonances decaying to eta_c pi+ pi- in two-photon interactions

The BABAR Collaboration, J. P. Lees, others

We report a study of the process gamma gamma -> X -> eta_c pi+ pi-, where X stands for one of the resonances chi_{c2}(1P), eta_c(2S), X(3872), X(3915), or chi_{c2}(2P). The analysi…

A selection of recent results from the BaBar experiment

V. Poireau

We present recent results from the BaBar collaboration in several areas of research. These include searches for new physics via measurements of radiative-penguin B decays, lepton-n…

Evidence for an excess of B -> D(*) Tau Nu decays

The BaBar Collaboration

Based on the full BaBar data sample, we report improved measurements of the ratios R(D(*)) = B(B -> D(*) Tau Nu)/B(B -> D(*) l Nu), where l is either e or mu. These ratios are sens…

Study of the reaction e^{+}e^{-} -->J/psiπ^{+}π^{-} via initial-state radiation at BaBar

The BABAR Collaboration

We study the process with initial-state-radiation events produced at the PEP-II asymmetric-energy collider. The data were recorded with the BaBar detector…

Measurement of Branching Fractions and Rate Asymmetries in the Rare Decays B -> K(*) l+ l-

The BABAR Collaboration

In a sample of 471 million BB events collected with the BABAR detector at the PEP-II e+e- collider we study the rare decays B -> K(*) l+ l-, where l+ l- is either e+e- or mu+mu-. W…
