First observation of a tau neutrino charged current interaction with charm production in the Opera experiment

N. Agafonova, A. Alexandrov, A. Anokhina +124

An event topology with two secondary vertices compatible with the decay of short-lived particles was found in the analysis of neutrino interactions in the Opera target. The observe…

Observation of the radiative decays of $Υ (1 S)$ to $χ_{c 1}$

P. Katrenko, I. Adachi, H. Aihara +166

We report the first observation of the radiative decay of the $Υ (1 S)$ into a charmonium state. The statistical significance of the observed signal of $Υ (1 S) \to γ χ_{c 1}$ is 6.3 sta…
