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…
