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…

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…
