The production of D+- and D0 mesons has been measured with the ZEUS detector at HERA using an integrated luminosity 133.6 pb-1. measurements cover kinematic range 5 < Q^2 1000 GeV^2, 0.02 y 0.7, 1.5 p_T^D 15 GeV eta^D 1.6. Combinatorial background to D meson signals is reduced by microvertex reconstruct displaced secondary vertices. Production cross sections are compared predictions next-to-leading-order QCD which found describe data well. Measurements extrapolated full phase space in order...
Next-to-leading-order QCD analyses of the ZEUS data on deep inelastic scattering together with fixed-target have been performed, from which gluon and quark densities proton value strong coupling constant αs(MZ) were extracted. The study includes a full treatment experimental systematic uncertainties including point-to-point correlations. resulting in parton density functions are presented. A combined fit for yields agreement world average. derived alone indicate importance HERA determining...
A resonance search has been made in the K0Sp and K0Sp̄ invariant-mass spectrum measured with ZEUS detector at HERA using an integrated luminosity of 121 pb−1. The was performed central rapidity region inclusive deep inelastic scattering ep centre-of-mass energy 300–318 GeV for exchanged photon virtuality, Q2, above 1 GeV2. Recent results from fixed-target experiments give evidence a narrow baryon decaying to K+n K0Sp, interpreted as pentaquark. presented here support existence such state,...
A small electromagnetic sampling calorimeter, installed in the ZEUS experiment 1995, significantly enhanced acceptance for very low x and Q^2 inelastic neutral current scattering, e^{+}p \to e^{+}X, at HERA. measurement of proton structure function F_2 total virtual photon-proton (\gamma^*p) cross-section is presented 0.11 \le Q^{2} 0.65 GeV^2 2 \times 10^{-6} 6 10^{-5}, corresponding to a range \gamma^{*}p c.m. energy 100 W 230 GeV. Comparisons with various models are also presented.
The NA62 experiment at CERN SPS is designed to study the $K^+\to\pi^+\nu\bar\nu$ decay. After collecting data in 2016, 2017, and 2018, has resumed taking 2021 received approval for operations until onset of LS3. first search lepton number violating decay $K^+\to\pi^0\pi^-\mu^+ e^+$ flavour decays $K^+\to\pi^0\pi^+\mu^+ e^-$ , $K^+\to\pi^0\pi^+\mu^- reported.
