Search for lepton-flavor-violating tau decays to $ℓ α$ at Belle

Belle Collaboration, K. Uno, K. Hayasaka +123

We report a search for the lepton-flavor-violating decays $τ^{\pm} \to ℓ^{\pm} α$ ~( $ℓ = e, μ$ ), where $α$ is an undetected spin-0 particle, such as an axion-like particle using $73…

Production cross sections of light and charmed mesons in $e^{+} e^{-}$ annihilation near 10.58 GeV

Belle Collaboration, R. Seidl, I. Adachi +131

We report measurements of production cross sections for $ρ^{+}$ , $ρ^{0}$ , $ω$ , $K^{*+}$ , $K^{* 0}$ , $ϕ$ , $η$ , $K_{S}^{0}$ , $f_{0} (980)$ , $D^{+}$ , $D^{0}$ , $D_{s}^{+}$ , $D^{*+}$ , $D^{* 0}$ , and $D^{*+}…

Search for $h_{b} (2 P) \to γ χ_{b J} (1 P)$ at $s = 10.860$ GeV

Belle Collaboration, A. Boschetti, R. Mussa +140

In the bottomonium sector, the hindered magnetic dipole (M1) transitions between P-wave states $h_{b} (2 P) \to χ_{b J} (1 P) γ$ , $J = 0, 1, 2$ , are expected to be severely su…
