Search for effective Lorentz and CPT violation using ZEUS data

ZEUS collaboration, I. Abt, R. Aggarwal +77

Lorentz and CPT symmetry in the quark sector of the Standard Model are studied in the context of an effective field theory using ZEUS $e^{\pm} p$ data. Symmetry-violating effects c…

Measurement of the cross-section ratio $σ_{ψ (2 S)} / σ_{J / ψ (1 S)}$ in exclusive photoproduction at HERA

ZEUS Collaboration, I. Abt, M. Adamus +80

The exclusive photoproduction reactions $γ p \to J / ψ (1 S) p$ and $γ p \to ψ (2 S) p$ have been measured at an $e p$ centre-of-mass energy of 318 GeV with the ZEUS detector at HERA using…
