Search for the decay $B_{s}^{0} \to η η$

Belle Collaboration, B. Bhuyan, K. J. Nath +184

We report results from a search for the decay $B_{s}^{0} \to η η$ using 121.4 fb $^{- 1}$ of data collected at the $Υ (5 S)$ resonance with the Belle detector at the KEKB asymmetric-e…

Measurements of the branching fractions of $Ξ_{c}^{0} \to Λ K_{S}^{0}$ , $Ξ_{c}^{0} \to Σ^{0} K_{S}^{0}$ , and $Ξ_{c}^{0} \to Σ^{+} K^{-}$ decays at Belle

Belle collaboration, Y. Li, J. X. Cui +213

Using the entire data sample of $980 fb^{- 1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we present measurements of the branching f…

Analysis of virtual meson production in solvable (1+1) dimensional scalar field theory

Yongwoo Choi, Ho-Meoyng Choi, Chueng-Ryong Ji +1

Light-front time-ordered amplitudes are investigated in the virtual scalar meson production process in (1+1) dimensions using the solvable scalar field theory extended from the con…

CMASS galaxy sample and the ontological status of the cosmological principle

Yigon Kim, Chan-Gyung Park, Hyerim Noh +1

The cosmological principle (CP), assuming spatially homogeneous and isotropic background geometry in the cosmological scale, is a fundamental assumption in modern cosmology. Recent…

A New Iron Emission Template for Active Galactic Nuclei. I. Optical Template for the H $β$ region

Daeseong Park, Aaron J. Barth, Luis C. Ho +1

We present a new empirical template for iron emission in active galactic nuclei (AGN) covering the $4000 - 5600$ A range. The new template is based on a spectrum of the narrow-line S…

First Measurement of the $Λ_{c}^{+} \to p η^{'}$ decay

Belle Collaboration, S. X. Li, J. X. Cui +197

We present the first measurement of the branching fraction of the singly Cabibbo-suppressed (SCS) decay $Λ_{c}^{+} \to p η^{'}$ with $η^{'} \to η π^{+} π^{-}$ , using a data sample corresponding to…
