Measurement of the hard exclusive muoproduction cross section at COMPASS
G. D. Alexeev, M. G. Alexeev, C. Alice +169
A new and detailed measurement of the cross section for hard exclusive neutral-pion muoproduction on the proton was performed in a wide kinematic region, with the photon virtuality…
Multiplicities of positive and negative pions, kaons and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target
G. D. Alexeev, M. G. Alexeev, C. Alice +166
The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable , th…
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 () could be produced in the bremsstrahlung-like reaction…
First constraints on the explanation of the muon anomaly from NA64- at CERN
Yu. M. Andreev, A. Antonov, D. Banerjee +58
The inclusion of an additional gauge symmetry would release the tension between the measured and the predicted value of the anomalous muon magnetic moment: this…
50 GeV in, nothing out: a sensitive probe of invisible and 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 and mesons in the NA64h experiment at the CERN SPS. Our…
