نویسنده
چکیده
Inclusive K0 s K 0 s production in deep inelastic ep scattering at HERA has been studied with the ZEUS detector using an integrated luminosity of 120 pb−1. Two states are observed at masses of 1537+9 −8 MeV and 1726±7 MeV, as well as an enhancement around 1300 MeV. The state at 1537 MeV is consistent with the well established f ′ 2(1525). The state at 1726 MeV may be the glueball candidate f0(1710). However, it’s width of 38 +20 −14 MeV is narrower than 125± 10 MeV observed by previous experiments for the f0(1710).

Measurements of vector mesons at HERA allow a detailed study of diffractive and non-diffractive production mechanisms, fragmentation and decay branching ratios. Results are presented on hadronic resonance measurements. In addition, the first observation of two meson states at masses around 1500 MeV and 1700 MeV are reported using inclusive K 0 s K 0 s production in deep inelastic ep scattering ...

Geometric scaling is a novel scaling phenomenon observed in deep inelastic scattering at small x: the total γ * p cross section depends upon the two kinematical variables Q 2 and x only via their combination ξ ≡ Q 2 R 2 0 (x), with R 2 0 (x) ∝ x λ. At sufficiently low Q 2 , below the saturation scale Q 2 s (x) (∼ a few GeV 2), this phenomenon finds a natural explanation as a property of the Col...

Recent results on light hadron spectroscopy are reported, with special emphasis on the evidence for a narrow baryonic state decaying to K 0 S p and K 0 S ¯ p, compatible with the pentaquark state θ + observed by fixed target experiments. The data were collected with the ZEUS detector at HERA using an integrated luminosity of 121 pb −1. The analyses were performed in the central rapidity region ...
