Precision measurement of the mass difference between light nuclei and anti-nuclei

A. Grigoryan, H. Gulkanyan, V. Papikyan, H. Bello Martinez et autres

The abundant production of (anti-)nuclei in relativistic heavy-ion collisions provides a platform to test the CPT invariance of nucleon–nucleon interactions—offering the highest precision measurement to date in the light-nuclei sector. The measurement of the mass differences for systems bound by the strong …

Observation of the strange sea in the proton via inclusive φ-meson production in neutral current deep inelastic scattering at HERA

S. Chekanov, D Krakauer, S Magill, B. Musgrave et autres

Inclusive φ(1020)-meson production in neutral current deep inelastic e+p scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 45 pb−1. The φ mesons were studied in the range 10<Q2<100 GeV2, where Q2 is the virtuality of …

Study of the azimuthal asymmetry of jets in neutral current deep inelastic scattering at HERA

S. Chekanov, D Krakauer, S Magill, B Musgrave et autres

The azimuthal distribution of jets produced in the Breit frame in high-Q2 deep inelastic e+p scattering has been studied with the ZEUS detector at HERA using an integrated luminosity of 38.6 pb−1. The measured azimuthal distribution shows a structure that is well …

Dijet cross sections in photoproduction at HERA

David Bailey, M. Derrick, D. Krakauer, S. Magill et autres

Dijet production by almost real photons has been studied at HERA with the ZEUS detector. Jets have been identified using the cone algorithm. A cut on xγOBS, the fraction of the photon energy participating in the production of the two jets of …
