50 GeV $π^{-}$ in, nothing out: a sensitive probe of invisible $η$ and $η^{'}$ decays with NA64h

Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54

We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar $η$ and $η^{'}$ mesons in the NA64h experiment at the CERN SPS. Our n…

First constraints on the $L_{μ} - L_{τ}$ explanation of the muon $g - 2$ anomaly from NA64- $e$ at CERN

Yu. M. Andreev, A. Antonov, D. Banerjee +58

The inclusion of an additional $U (1)$ gauge $L_{μ} - L_{τ}$ symmetry would release the tension between the measured and the predicted value of the anomalous muon magnetic moment: this pa…
