Observation of a structure in the M invariant mass distribution near 1700 MeV/ in the reaction
V. Metag, M. Nanova, J. Hartmann +74
The reaction has been studied with the CBELSA/TAPS detector at the electron stretcher accelerator ELSA in Bonn for incident photon energies from threshold…
Improved exclusion limit for light dark matter from annihilation in NA64
Yu. Andreev, D. Banerjee, J. Bernhard +55
The current most stringent constraints for the existence of sub-GeV dark matter coupling to Standard Model via a massive vector boson were set by the NA64 experiment for…
The exotic meson with and its decay into
M. G. Alexeev, G. D. Alexeev, A. Amoroso +192
We study the spin-exotic amplitude in single-diffractive dissociation of 190 GeV pions into using a hydrogen target and confirm the $π_1(1600) \to…
Probing the explanation of the muon (g-2) anomaly and thermal light dark matter with the semi-visible dark photon channel
C. Cazzaniga, P. Odagiu, E. Depero +55
We report the results of a search for a new vector boson () decaying into two dark matter particles of different mass. The heavier particle subsequently decays…
Probing transversity by measuring polarisation in SIDIS
M. G. Alexeev, G. D. Alexeev, A. Amoroso +196
Based on the observation of sizeable target-transverse-spin asymmetries in single-hadron and hadron-pair production in Semi-Inclusive measurements of Deep Inelastic Scattering (SID…
Search for pseudoscalar bosons decaying into pairs in the NA64 experiment at the CERN SPS
Yu. M. Andreev, D. Banerjee, J. Bernhard +52
We report the results of a search for a light pseudoscalar particle that couples to electrons and decays to performed using the high-energy CERN SPS H4 electron beam.…
