Observation of $τ^{-} \to π^{-} ν_{τ} e^{+} e^{-}$ and search for $τ^{-} \to π^{-} ν_{τ} μ^{+} μ^{-}$

Belle Collaboration, Y. Jin, H. Aihara +195

We present the first measurements of branching fractions of rare tau-lepton decays, $τ^{-} \to π^{-} ν_{τ} ℓ^{+} ℓ^{-}$ ( $ℓ = e$ or $μ$ ), using a data sample corresponding t…

A Study of NaI(Tl) crystal Encapsulation using Organic scintillators for the Dark Matter Search

J. Y. Lee, G. Adhikari, C. Ha +5

Scintillating NaI(Tl) crystals are used for various rare decay experiments, such as dark matter searches. The hygroscopicity of NaI(Tl) crystal makes the construction of crystal de…

Test of lepton flavor universality and search for lepton flavor violation in $B \to K ℓℓ$ decays

S. Choudhury, S. Sandilya, K. Trabelsi +220

We present measurements of the branching fractions for the decays $B \to K μ^{+} μ^{-}$ and $B \to K e^{+} e^{-}$ , and their ratio ( $R_{K}$ ), using a data sample of 711 $f b^{- 1}$ that…

Search for $X (3872)$ and $X (3915)$ decay into $χ_{c 1} π^{0}$ in $B$ decays at Belle

V. Bhardwaj, S. Jia, I. Adachi +190

The Belle experiment searched for the exotic states X(3872) and X(3915) decaying to χc1 π0 in B⁺ → χc1 π0 K⁺ decays and set upper limits on the product branching fractions.

Observation of a new structure near 10.75 GeV in the energy dependence of the $e^{+} e^{-} \to Υ (n S) π^{+} π^{-}$ ( $n = 1, 2, 3$ ) cross sections

R. Mizuk, A. Bondar, I. Adachi +177

We report a new measurement of the $e^{+} e^{-} \to Υ (n S) π^{+} π^{-}$ ( $n = 1, 2, 3$ ) cross sections at energies from 10.52 to 11.02 GeV using data collected with the Belle detector at the KEKB as…
