Search for a light muon-philic $Z^\prime$ with the NA64-$e$ experiment at CERN

D. Banerjee, B. Banto Oberhauser, J. Bernhard, P. Bisio et autres

The extension of Standard Model made by inclusion of additional $U(1)$ gauge $L_μ-L_τ$ symmetry can explain the difference between the measured and the predicted value of the muon magnetic moment and solve the tension in $B$ meson decays. This model predicts the …

Double $J/ψ$ production in pion-nucleon scattering at COMPASS

G. D. Alexeev, M. G. Alexeev, A. Amoroso, V. Andrieux et autres

We present the study of the production of double $J/ψ$ mesons using COMPASS data collected with a 190 GeV/$c$ $π^-$ beam scattering off NH$_{3}$, Al and W targets. Kinematic distributions of the collected double $J/ψ$ events are analysed, and the double $J/ψ$ …

Transverse-momentum-dependent multiplicities of charged hadrons in muon-deuteron deep inelastic scattering

M. Aghasyan, Maxim Alexeev, G. D. Alexeev, A. Amoroso et autres

A semi-inclusive measurement of charged hadron multiplicities in deep inelastic muon scattering off an isoscalar target was performed using data collected by the COMPASS Collaboration at CERN. The following kinematic domain is covered by the data: photon virtuality ${Q}^{2}>1\text{ }\text{ }(\mathrm{GeV}/c{)}^{2}$, invariant …
