Shedding light on Dark Sectors with high-energy muons at the NA64 experiment at the CERN SPS

Yu. M. Andreev, D. Banerjee, B. Banto Oberhauser +54

A search for Dark Sectors is performed using the unique M2 beam line at the CERN Super Proton Synchrotron. New particles ( $X$ ) could be produced in the bremsstrahlung-like reaction…

First constraints on the $L_{I^} ¼ - L_{I ¨} $ 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_{I^} ¼ - L_{I ¨} $ symmetry would release the tension between the measured and the predicted value of the anomalous muon magnetic moment: this…

50 GeV $I ¨ ^{-}$ in, nothing out: a sensitive probe of invisible $I^\cdot$ and $I^\cdot^{'}$ 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 $I^\cdot$ and $I^\cdot^{'}$ mesons in the NA64h experiment at the CERN SPS. Our…
