Observation of the Electromagnetic Dalitz Transition $h_{c} \to e^{+} e^{-} η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +504

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ decays and data samples of $e^{+} e^{-}$ collisions with $s$ from 4.130 to 4.780~GeV collected with the BESIII detector, we report the…

Study of $χ_{b J} (2 P) \to ω Υ (1 S)$ at Belle

Belle Collaboration, Z. S. Stottler, T. K. Pedlar +179

We report a study of the hadronic transitions $χ_{b J} (2 P) \to ω Υ (1 S)$ , with $ω \to π^{+} π^{-} π^{0}$ , using $28.2 \times 1 0^{6} Υ (3 S)$ mesons recorded by the Belle detector. We present the…

Measurement of the polarizations of prompt and non-prompt J/ $ψ$ and $ψ$ (2S) mesons produced in pp collisions at $s$ = 13 TeV

CMS Collaboration

The polarizations of prompt and non-prompt J $/ ψ$ and $ψ$ (2S) mesons are measured in proton-proton collisions at $s$ = 13 TeV, using data samples collected by the CMS experim…

Search for Two-Body $B$ Meson Decays to $Λ^{0}$ and $Ω_{c}^{(*) 0}$

Belle Collaboration, V. Savinov, I. Adachi +146

We report the results of the first search for Standard Model and baryon-number-violating two-body decays of the neutral $B$ mesons to $Λ^{0}$ and $Ω_{c}^{(*) 0}$ using 711~${\rm fb^{-…

Search for production of a single vector-like quark decaying to tH or tZ in the all-hadronic final state in pp collisions at $s$ = 13 TeV

CMS Collaboration

A search for electroweak production of a single vector-like T quark in association with a bottom (b) quark in the all-hadronic decay channel is presented. This search uses proton-p…
