Long-range azimuthal correlations for partially coherent pion emission in proton-proton collisions

Long-range multiplicity correlations in proton-proton collisions

The forward-backward long-range multiplicity correlations in proton-proton collisions are investigated in the model with two independent sources of particles: one leftand one right-moving wounded nucleon. A good agreement with the UA5 collaboration proton-antiproton data at the c.m. energy of 200 GeV is observed. For comparison the model with only one source of particles is also discussed. PACS...

Long range forward-backward rapiditiy correlations in proton-proton collisions at LHC

We argue that string percolation is in the origin of i) an approximately flat rapidity distribution and of ii) an approximately constant forward-backward correlation parameter b over a substantial fraction of the available rapidity. Predictions are given for pp collisions at LHC, √ s = 14TeV and √ s = 5.5TeV.

Angular distribution and azimuthal asymmetry for pentaquark production in proton-proton collisions

Angular distributions for production of the Θ pentaquark are calculated for the collisions of polarized protons with polarized target protons. We compare calculations based on different assumptions concerning spin and parity (J = 1/2, 3/2) of the Θ state. For a wide class of interactions the spin correlation parameters describing the asymmetric angular distributions are calculated up to 250 MeV...
