Search for a Dark Leptophilic Scalar at BABAR

The BABAR Collaboration

Many scenarios of physics beyond the Standard Model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constrai…

Measurement of the spectral function for the $τ^{-} \to K^{-} K_{S} ν_{τ}$ decay

The BaBar Collaboration

The decay $τ^{-} \to K^{-} K_{S} ν_{τ}$ has been studied using $430 \times 1 0^{6}$ $e^{+} e^{-} \to τ^{+} τ^{-}$ events produced at a center-of-mass energy around 10.6 GeV at the PEP-II collider and stu…

First evidence for $cos 2 β > 0$ and resolution of the CKM Unitarity Triangle ambiguity by a time-dependent Dalitz plot analysis of $B^{0} \to D^{(*)} h^{0}$ with $D \to K_{S}^{0} π^{+} π^{-}$ decays

The BaBar, Belle Collaborations, : +422

We present first evidence that the cosine of the CP-violating weak phase $2 β$ is positive, and hence exclude trigonometric multifold solutions of the CKM Unitarity Triangle using a…

Study of the process $e^{+} e^{-} \to π^{+} π^{-} η$ using initial state radiation

The BABAR Collaboration

We study the process $e^{+} e^{-} \to π^{+} π^{-} η γ$ , where the photon is radiated from the initial state. About 8000 fully reconstructed events of this process are selected from the BaBar d…

Search for a light Higgs resonance in radiative decays of the Y(1S) with a charm tag

The BABAR Collaboration

A search is presented for the decay Y(1S) -> gamma A0, A0 -> cc-bar, where A0 is a candidate for the CP-odd Higgs boson of the next-to-minimal supersymmetric standard model. The se…
