W latach 1946–1947 komuniści stopniowo rozprawili się z legalną opozycją polityczną spod znaku Polskiego Stronnictwa Ludowego. Ogłoszona w ślad za tym amnestia okazała druzgocącym ciosem dla podziemia kontynuującego działalność okresu drugiej wojny światowej. tej sytuacji szczególnego znaczenia zaczęła nabierać opozycyjna wśród młodzieży dorastającej już okresie powojennym. Postępująca sowietyz...

The photoproduction of beauty quarks in events with two jets and a muon has been measured with the ZEUS detector at HERA using an integrated luminosity of 110 pb. The fraction of jets containing b quarks was extracted from the transverse momentum distribution of the muon relative to the closest jet. Differential cross sections for beauty production as a function of the transverse momentum and p...

The production of beauty quarks with a D and a muon in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb. Low transverse-momentum thresholds for the muon and D meson allow a measurement of beauty production closer to the production threshold than previous measurements. The beauty signal was extracted using the charge correlations and angul...

Mean values and differential distributions of event-shape variables have been studied in neutral current deep inelastic scattering using an integrated luminosity of 82.2 pb collected with the ZEUS detector at HERA. The kinematic range was 80 < Q < 20 480GeV and 0.0024 < x < 0.6, where Q is the virtuality of the exchanged boson and x is the Bjorken variable. The data are compared with a model ba...

A search for narrow-width resonances that decay into electron+jet or neutrino+jet has been performed with the ZEUS detector at HERA operating at center-of-mass energies of 300 and 318 GeV. An integrated ep luminosity of 114.8 pb and ep luminosity of 16.7 pb were used. No evidence for any resonance was found. Limits were derived on the Yukawa coupling, λ, as a function of the mass of a hypotheti...

Dijet angular distributions of photoproduction events in which a D meson is produced in association with one of two energetic jets have been measured with the ZEUS detector at HERA, using an integrated luminosity of 120 pb. Differential cross sections as a function of the angle between the charm-jet and the proton-beam direction in the dijet rest frame have been measured for samples enriched in...

Diffractive photoproduction of D(2010) mesons was measured with the ZEUS detector at the ep collider HERA, using an integrated luminosity of 78.6 pb. The D mesons were reconstructed in the kinematic range: transverse momentum pT (D ) > 1.9GeV and pseudorapidity |η(D∗)| < 1.6, using the decay D → Dπ s followed by D → Kπ (+c.c.). Diffractive events were identified by a large gap in pseudorapidity...

Dijet production has been studied in neutral current deep inelastic ep scattering for 470 < Q < 20000 GeV with the ZEUS detector at HERA using an integrated luminosity of 38.4 pb. Dijet differential cross sections are presented in a kinematic region where both theoretical and experimental uncertainties are small. Next-to-leading-order (NLO) QCD calculations describe the measured differential cr...
