A new search for the $K_{L} \to π^{0} ν ν$ and $K_{L} \to π^{0} X^{0}$ decays

J. K. Ahn, K. Y. Baek, S. Banno +87

We searched for the $C P$ -violating rare decay of neutral kaon, $K_{L} \to π^{0} ν ν$ , in data from the first 100 hours of physics running in 2013 of the J-PARC KOTO experimen…

Study of the K0(L) --> pi0 pi0 nu nu-bar decay

E391a Collaboration, R. Ogata, S. Suzuki +67

The rare decay K0(L) --> pi0 pi0 nu nu-bar was studied with the E391a detector at the KEK 12-GeV proton synchrotron. Based on 9.4 x 10^9 K0L decays, an upper limit of 8.1 x 10^{-7}…

Experimental study of the decay $K_{L}^{0} \to π^{0} ν ν ˉ$

The E391a Collaboration, J. K. Ahn

The first dedicated search for the rare neutral-kaon decay $K_{L}^{0} \to π^{0} ν ν ˉ$ has been carried out in the E391a experiment at the KEK 12-GeV proton synchrotron. The final upper li…

Search for a light pseudoscalar particle in the decay $K_{L}^{0} \to π^{0} π^{0} X$

Y. C. Tung, Y. B. Hsiung, M. L. Wu +59

We performed a search for a light pseudoscalar particle $X$ in the decay $K_{L}^{0} - > p i 0 p i 0 X$ , $X - > γ γ$ with the E391a detector at KEK. Such a particle with a mass of 214.3 MeV/ $c^{2}$ wa…

Measurement of $A_{c}$ with Charmed Mesons at SLD

The SLD Collaboration, K. Abe

We present a direct measurement of the parity-violation parameter $A_{c}$ in the coupling of the $Z^{0}$ to $c$ -quarks with the SLD detector. The measurement is based on a sample of 53…

Search for Charmless Hadronic Decays of B Mesons with the SLD Detector

SLD Collaboration

Based on a sample of approximately 500,000 hadronic Z0 decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body e…

Measurement of the Charged Multiplicity of $Z \to b b$ Events

The SLD Collaboration

Using an impact parameter tag to select an enriched sample of $Z \to b b$ events, we have measured the difference between the average charged multiplicity of $Z…

Precise Measurement of the Left-Right Cross Section Asymmetry in $Z$ Boson Production by $\ee$ Collisions

The SLD Collaboration

We present a precise measurement of the left-right cross section asymmetry ( $A_{L R}$ ) for $Z$ boson production by $\ee$ collisions. The measurement was performed at a center-of-mas…
